The Origins and Evolution of the Round Brilliant Cut

The round brilliant cut diamond traces its origins back to the 18th century, a time when diamond experts sought to create a stone that would dazzle with unparalleled sparkle. However, the tools and technology available at the time fell short of achieving this ideal cut. It wasn't until the late 20th century, with the invention of the diamond-cutting saw, that a breakthrough occurred.

In the early 1900s, renowned diamond expert Marcel Tolkowski played a crucial role by defining the ideal proportions for a round brilliant cut diamond. His meticulous calculations paved the way for the precise execution of this iconic cut, utilizing advancements in technology such as lasers to reveal its true perfection.

Characterized by its circular shape and multiple precisely angled facets, the round brilliant cut combines elegance with brilliance and enjoys immense popularity. With 57 precisely angled facets, 33 on the crown and 25 on the pavilion, this cut maximizes light reflection and dispersion, creating the diamond's signature sparkle.

The modern round brilliant cut, as defined by Tolkowsky in 1919, has become the standard and most sought-after diamond shape. Advancements in diamond cutting tools, including the bruting machine and lasers, have allowed for the consistent execution of Tolkowsky's ideal proportions.

Today, the round brilliant cut remains the most popular and sought-after diamond shape, renowned for its timeless elegance and unmatched sparkle. With its ideal proportions, exceptional symmetry, and polish, the round brilliant cut diamond continues to captivate hearts and minds, standing as a testament to enduring beauty and craftsmanship.

Characteristics and Advantages

Round brilliant cut diamonds possess distinctive characteristics that set them apart as the epitome of elegance and brilliance in the world of jewelry. With their symmetrical circular shape and precisely arranged facets totaling 57 or 58, these diamonds are engineered to captivate with their exceptional fire, brilliance, and versatility.

The facets of a round brilliant cut diamond are meticulously designed to optimize light performance, reflecting and dispersing light to create a mesmerizing display of brilliance and scintillation. The crown features 33 facets, including the table, bezel facets, star facets, and upper girdle facets, while the pavilion boasts 25 facets, including lower girdle facets, pavilion main facets, and an optional culet. These carefully engineered proportions, including depth percentage, table size, and angles, ensure that the diamond shines with unparalleled radiance.

As the most popular diamond shape, accounting for approximately 75% of all diamonds sold, round brilliant cut diamonds are cherished for their timeless appearance and exceptional optical properties. Their brilliance, fire, and scintillation are unrivaled, creating a dazzling spectacle that captivates the eye.

Brilliance refers to the diamond's ability to reflect and refract light, resulting in a sparkling appearance, while fire is the dispersion of white light into the spectral colors of the rainbow, adding a fiery allure to the diamond's surface. Scintillation, on the other hand, encompasses the flashes of color visible when the diamond is in motion, highlighting its dynamic beauty.

The versatility of the round brilliant cut makes it a favorite choice for a wide range of jewelry styles, from classic solitaire settings to elaborate halo or three-stone designs. Its symmetrical shape and brilliant performance complement any metal color and wedding band, offering endless possibilities for personalization and highlighting the popularity of round cut diamonds.

In essence, the round brilliant cut diamond stands as a testament to exquisite craftsmanship and timeless elegance, embodying the perfect balance of beauty and brilliance that has captivated hearts for centuries.

How to Evaluate Round Brilliant Cut Diamonds

Assessing Cut Quality: The quality of the cut is the single most critical factor when evaluating round brilliant cut diamonds. It directly influences the diamond's brilliance, fire, and overall visual appeal. Here's what to look for:

Proportions: Optimal proportions play a crucial role in maximizing a diamond's light performance. Look for a table diameter of 54-57%, depth of 61-62.5%, and crown angle of 34-35 degrees. These proportions ensure that light entering the diamond is reflected and refracted effectively, resulting in maximum sparkle.

Polish and Symmetry: The polish and symmetry of a diamond determine the precision of its faceting, which directly impacts its light performance. Diamonds with Excellent or Very Good polish and symmetry ratings from reputable labs like GIA or AGS exhibit superior craftsmanship and light reflection.

Brightness, Fire, and Scintillation: These three aspects collectively contribute to a diamond's visual appeal. Brightness refers to the overall white light reflection from the diamond's surface, while fire refers to the dispersion of light into spectral colors. Scintillation refers to the sparkle or flashes of light observed when the diamond moves. An excellently cut diamond will display a perfect balance of brightness, fire, and scintillation under various lighting conditions.

Certification: It's essential to verify the diamond's quality through an independent grading report from a reputable laboratory. Reports from GIA (Gemological Institute of America) or AGS (American Gem Society) provide an objective assessment of the diamond's 4Cs (cut, color, clarity, and carat weight), ensuring transparency and peace of mind for the buyer.

Factors to Consider

Cut: The cut quality significantly influences a diamond's brilliance and fire. Aim for diamonds with an "Excellent" or "Ideal" cut grade, as they are meticulously crafted to maximize light performance and beauty.

Color: Diamond color is graded on a scale from D (colorless) to Z (light yellow or brown). While colorless diamonds (D-F) are highly prized for their purity, near-colorless diamonds (G-J) offer excellent value without compromising beauty. Consider choosing a color grade that complements your preferences and budget.

Clarity: Clarity refers to the presence of internal characteristics (inclusions) and external imperfections (blemishes) within the diamond. Diamonds with higher clarity grades, such as Flawless (FL) or Internally Flawless (IF), are rare and command higher prices. However, diamonds with slightly lower clarity grades, such as VS (Very Slightly Included) or SI (Slightly Included), are often "eye-clean," meaning their imperfections are not visible to the naked eye. This allows you to prioritize visual appeal while maximizing value.

Carat: Carat weight measures a diamond's size, with one carat equivalent to 0.2 grams. While carat weight is a crucial factor in determining a diamond's price, it's essential to balance size with cut quality. A well-cut diamond with slightly lower carat weight can appear larger and more brilliant than a larger diamond with inferior cut quality.

Tips for Selecting Diamonds within Budget

Prioritize Cut Quality: The cut of a diamond has the most significant impact on its sparkle and beauty. Allocate a significant portion of your budget to ensure you get the best cut quality possible.

When buying round cut diamonds, consider Lower Color Grades for a better value without compromising too much on appearance. Near-colorless diamonds (H or I) offer excellent value, as they appear colorless when set in jewelry. You can save significantly by choosing a slightly lower color grade without sacrificing visual appeal.

Opt for Eye-Clean Clarity: Look for diamonds with clarity grades of VS2 or SI1, as they typically have imperfections that are not visible to the naked eye. This allows you to enjoy a beautiful diamond without paying a premium for higher clarity grades.

Be Flexible with Carat Weight: Don't fixate solely on carat weight. Consider diamonds with slightly lower carat weight but excellent cut quality, as they can offer exceptional beauty and value.

Explore Fancy Shapes like pear, emerald, cushion, marquise, and radiant to diversify your jewelry collection beyond the popularity of the traditional round cut. Fancy-shaped diamonds, such as princess or oval cuts, often cost less than round brilliant diamonds of similar quality. Explore these options to maximize your budget without compromising on appearance.

Evaluate Fluorescence: Some diamonds exhibit fluorescence when exposed to ultraviolet light. While strong fluorescence can affect a diamond's appearance, faint to medium fluorescence is often not visible to the naked eye and can offer cost savings without compromising beauty.

Care and Maintenance

Regular Cleaning Routine

Maintaining the brilliance of your round brilliant cut diamond requires a consistent cleaning regimen. Begin by preparing a gentle cleaning solution using warm water and equal parts of dish soap and ammonia-based products such as Windex. This solution effectively removes dirt and grime without harming the diamond's sparkle.

However, it's essential to note that this cleaning solution is suitable for most gemstones but not recommended for porous stones such as Pearls, Coral, Emerald, Opal, Amber, Onyx, and Agate. If you're unsure about the suitability of this solution for your particular gemstone, feel free to reach out to us for guidance.

When cleaning your diamond jewelry, use a child's toothbrush to minimize the risk of potential damage to the stones. Dip the toothbrush into the cleaning solution and gently scrub the diamond and its setting, paying close attention to areas where dirt and oil tend to accumulate, such as around the prongs and underneath the diamond. Use light, circular motions to avoid scratching the metal or diamond surface.

After scrubbing, rinse the jewelry under lukewarm running water to remove any remaining soap residue. Be sure to use a gentle stream of water to prevent splashing and potentially losing the piece down the drain. Once rinsed, pat the jewelry dry with a clean, lint-free cloth, ensuring to remove any excess moisture from both the diamond and the metal setting.

Following these cleaning steps regularly will help maintain the beauty and sparkle of your round brilliant cut diamond jewelry for years to come. If you have any questions or concerns about cleaning your specific piece, don't hesitate to contact us for personalized guidance.

Professional Cleaning and Inspection

While regular at-home cleaning is essential for maintaining the appearance of your round brilliant cut diamond jewelry, periodic professional cleaning and inspection are equally important. Approximately every 6-12 months, consider taking your jewelry to a reputable jeweler for a thorough cleaning and inspection.

During a professional cleaning, jewelers utilize specialized equipment and cleaning solutions to remove stubborn dirt and grime that may be missed during at-home cleanings. Additionally, jewelers can inspect the diamond and its setting for any signs of damage or wear, such as loose stones or weakened prongs. Addressing these issues promptly can prevent more extensive damage and ensure the longevity of your jewelry.

Avoid Harsh Chemicals

When wearing your round brilliant cut diamond jewelry, take care to avoid exposure to harsh chemicals and abrasive substances. Chemicals commonly found in household cleaners, beauty products, and even certain foods can damage the round cut diamond and its setting over time. Additionally, abrasive materials like toothpaste and baking soda can scratch the metal and dull the diamond's brilliance.

To protect your jewelry from chemical damage, remove it before engaging in activities that involve exposure to harsh substances. This includes cleaning, swimming, and applying lotions or perfumes. By taking proactive measures to minimize exposure to harmful chemicals, you can preserve the beauty and integrity of your round brilliant cut diamond jewelry for years to come.

Safe Storage Practices

Proper storage is essential for preventing damage and preserving the longevity of your round brilliant cut diamond jewelry. When not being worn, store your jewelry in a dedicated jewelry box or pouch to protect it from dust, dirt, and other environmental factors. Avoid storing multiple pieces of jewelry together, as this can increase the risk of scratches and damage caused by friction between the pieces.

Use Dedicated Storage: Store your jewelry in a designated ring dish, jewelry box, or pouch to prevent scratching, tangling, or damage from contact with other items. Individual compartments help keep each piece separate and protected.

Avoid Metal-on-Metal Contact: Diamonds are incredibly durable, but they can still scratch other surfaces, including metal. Store your diamond jewelry away from other metal pieces to prevent scratches and maintain its pristine appearance.
Choose a Safe Location: Store your jewelry in a cool, dry place away from direct sunlight and humidity, as exposure to these elements can degrade the metal and affect the diamond's brilliance over time.

    Consider Jewelry Organizers: Invest in jewelry organizers or trays with padded compartments to keep your pieces organized and secure. These organizers can help prevent tangling and make it easier to locate specific items when needed.

    Cleaning Frequency


    To maintain the optimal sparkle and brilliance of your round brilliant cut diamond jewelry, adhere to a regular cleaning schedule. Here's a recommended cleaning frequency:

    Every 2 Weeks: Perform a gentle cleaning using a soft-bristled toothbrush and mild soap solution. This routine removes everyday dirt, oils, and residues that accumulate on the diamond's surface.

    Once a Month: Conduct a more thorough cleaning by soaking the jewelry in a gentle cleaning solution for 20-40 minutes before scrubbing it with a soft brush. This deep cleaning eliminates embedded grime and restores the diamond's luster.

    Twice a Year: Schedule professional cleanings and inspections with a reputable jeweler. Professional cleaning ensures that stubborn dirt and contaminants are effectively removed, while inspections detect any potential issues such as loose stones or damaged settings.

    Recognizing Cleaning Needs

    Understanding when your round brilliant cut diamond jewelry requires cleaning is crucial for maintaining its appearance and longevity. Look out for these signs that indicate it's time for a cleaning:

    Diminished Brilliance: If your diamond appears dull or lacks its usual sparkle, it may be due for a cleaning. Dirt and oils can accumulate on the diamond's surface, hindering its ability to reflect light effectively.

    Visible Residue: Visible dirt, grime, or discoloration on the diamond or its setting are clear indicators that cleaning is necessary. Regular wear exposes jewelry to environmental pollutants that can adhere to its surface over time.

    Oily or Greasy Appearance: If the diamond appears oily or greasy, it suggests a buildup of lotions, oils, or other residues. This buildup not only affects the diamond's aesthetics but also compromises its brilliance.

    Avoiding Common Cleaning Mistakes

    While cleaning your round brilliant cut diamond jewelry, steer clear of these common mistakes to safeguard its integrity:

    Using Harsh Chemicals: Avoid using harsh chemicals such as bleach, lemon juice, or vinegar, as they can damage both the metal setting and the diamond itself. Stick to gentle cleaning solutions formulated specifically for jewelry.

    Abrasive Scrubbing: Refrain from scrubbing the jewelry with abrasive materials like toothpaste or baking soda, as these can scratch the diamond and damage the metal. Opt for soft-bristled brushes and gentle cleaning techniques instead.

    Excessive Heat Exposure: Avoid subjecting your jewelry to extreme heat, such as boiling or prolonged exposure to direct sunlight. Heat can weaken adhesives and cause discoloration or damage to the metal and gemstones.

    Wearing Jewelry in Hazardous Environments: Remove your jewelry before engaging in activities that pose a risk of damage, such as swimming or participating in sports. Chemicals, chlorine, and physical impact can all compromise the integrity of your jewelry.

    Additional Care Tips

    In addition to regular cleaning and proper storage, consider these additional care tips to prolong the lifespan of your round brilliant cut diamond jewelry:

    Regular Inspections: Periodically inspect your jewelry for loose stones, damaged settings, or signs of wear and tear. Promptly address any issues by seeking professional repair services to prevent further damage.

    Avoid Excessive Wear: While round brilliant cut diamonds are incredibly durable, they are not indestructible. Avoid wearing your jewelry during activities that may subject it to excessive force, impact, or abrasion.

    Professional Maintenance: Schedule regular maintenance appointments with a reputable jeweler to assess the condition of your diamond jewelry and perform any necessary repairs or adjustments. Professional cleaning and inspection can help detect issues early and prevent costly damage.


    In conclusion, the round brilliant cut diamond stands as a timeless symbol of elegance and sophistication, capturing hearts for over a century with its unparalleled brilliance and enduring appeal. Renowned for its classic round shape and exceptional sparkle, the round brilliant cut diamond remains the most popular choice in the jewelry market, coveted for its ability to command attention and take center stage in any setting.

With options such as the old European cut and old mine cut also available in the market, the versatility and timelessness of the round brilliant cut diamond are further underscored.
