CLAIRONNE JEWELS

IGI Certified Diamonds

All CLAIRONNE JEWELS lab-grown diamonds are independently certified by the International Gemological Institute (IGI), one of the world's most trusted gemological laboratories. Every lab-grown diamond comes with an official IGI grading report and a unique laser-inscribed report number for easy verification and complete confidence in your purchase.

Natural diamonds are accompanied by an IGI grading report only for products where the listing specifically states "IGI Certified." If a natural diamond listing does not indicate IGI certification, it is not sold with an IGI grading report.

Our lab-grown diamonds are chemically, physically, and optically identical to mined diamonds, offering the same brilliance and durability at exceptional value.

The 4 Cs of Diamond Quality

  • CUT

    Quality of the diamond's proportions, symmetry, and polish. Excellent cut creates the most brilliance and fire.

  • COLOR

    Absence of color in diamond, graded from D (colorless) to Z (light yellow). Less color means higher value.

  • CLARITY

    Clarity refers to the absence of inclusions and blemishes. Higher clarity means greater rarity and value.

  • CARAT WEIGHT

    A measure of a diamond's weight, with one carat equal to 0.2 grams. A larger carat weight means a larger diamond.
