Carat is the unit of measurement for the physical weight of diamonds, and is one of the most objective measurements of the “Four Cs” for determining the value of a diamond. One carat is equal to 200 milligrams, or 1/5 gram, and is subdivided into 100 “points”. This allows very precise measurements to the hundredth decimal place.

Cut refers to a diamond’s proportions, symmetry, and polish of the facets by the expert cutter. Cut does not refer to the shape of a diamond, such as cushion or princess. Cut determines a diamond’s ability to reflect and refract light, which directly affects a diamond’s beauty. With a better cut, the diamond will exhibit more fire, brilliance, and scintillation. Cut is graded by experts as Fair, Good, Very Good, Excellent, and Ideal.

A diamond’s clarity refers to the presence of impurities on and within the stone. Even when grown in a lab, tiny imperfections might be visible. These are called flaws or inclusions. They form during the growing process and are unique to each stone. The term "eye clean" refers to diamonds whose inclusions generally cannot be seen without magnification, and are typically graded SI or higher on the clarity scale.

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.
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.

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.
