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.

Lab created diamonds are real diamonds. Lab grown diamonds are chemically, physically and optically identical to natural diamonds. The key difference lies in their origin – while natural diamonds are formed in the Earth’s mantle over billions of years, lab created diamonds are grown in controlled environments using advanced technological processes. This makes them a more ethical choice without compromising quality or brilliance.

Yes. Lab grown diamonds are simple to appraise and insure. Depending on the policy, this may protect them against loss, theft or damage.  Your Grown Brilliance receipt or invoice will typically suffice in order to obtain insurance for your lab grown diamond jewelry from your insurer.

Similar to mined diamonds, lab created diamonds value is determined by many factors, including the costs to produce them, market demand, and the quality of the diamond. Most diamonds, both mined and lab created, 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. Keep your diamond’s certification because this is important if you decide to sell.
