A grading report or diamond certificate is an independent, expert opinion on the quality of the diamond. Gemologists from the world's leading grading labs use special equipment to measure the weight and dimensions of the diamond and assess quality characteristics such as cut, color, and clarity. Grown Brilliance only utilizes the most distinguished grading labs.Please contact us to request the grading report.

L:W Ratio
L:W Ratio - Length to Width Ratio

The length-to-width ratio compares the length of a diamond to its width to show how elongated a fancy-shaped diamond appears when viewed from the top. Length-to-width ratio is a matter of personal preference with some individuals preferring a more elongated shape and others a more equal or square shape. It is calculated as length divided by width.


Fluorescence refers to a diamond's tendency to emit a soft colored glow when subjected to ultraviolet light (such as a "black light"). Overall, diamond fluorescence should not be a major factor in the purchase of a diamond since its effects are negligible. Fluorescence grades include Very Strong, Strong, Medium, Faint, None.


Polish describes the finish of the facets of the diamond. Polish is graded as Poor, Fair, Good, Very Good, Excellent, or Ideal. Polish grades of Good or higher have the least effect on the brilliance of the diamond and are suitable for the finest quality jewelry.


Diamond Symmetry refers to how well aligned the facets of a diamond are. Symmetry impacts how well a diamond interacts with light and how brilliant a diamond is. Symmetry grades are measured as Excellent, Very Good, Good, Fair and Poor.

Table %

The table is the largest facet of a gemstone, and is located at the top. Table % is the table width as a percentage of the girdle diameter.

Diamond Anatomy
Depth %

Diamond depth is a factor of a diamond's cut. The depth of diamond is its height measured from the culet (bottom tip) to the table (flat, top surface). The diamond depth percentage is calculated by dividing total depth by the average diameter, then multiplying by 100.

Regular care can keep your diamonds clean and sparkly. Simply clean them with warm water and a soft toothbrush. You can also get your jewelry professionally cleaned once a year. When traveling, be sure to store your diamonds and/or rings in a box or container to prevent them from getting damaged.

If you wear a diamond ring, consider taking it off before going to bed, applying lotion, using cleaning products, and spraying perfume. This can help ensure the piece lasts for many years.

Similar to mined diamonds, lab created diamonds have a resale value and sell for a portion of the original sale price. You can receive a higher value based on several factors, such as if the diamond is in good condition and has excellent quality. Be sure to also keep your diamond’s certification because this is important if you decide to sell.
