Custom Design Collection

Settings   Fit for a Queen: Natural Alexandrite Cocktail Ring in 18k White Gold   This show-stopping cocktail ring has been created to reflect old-world opulence and luxury at its finest, down to the details of the delicate open-work setting. It features a rare 2.36ct pear-shaped natural alexandrite, accented by smaller pear-shaped alexandrite and sixty-five round brilliant cut diamonds.  Breathtaking style, effortless elegance, and noteworthy refinement. This cocktail ring is the perfect choice for those who seek a different style and unique arrangement of natural alexandrites and diamonds.   Stone   The unique feature of this ring is that gorgeous 2.36ct center alexandrite is remarkably clean which makes it very rare because alexandrite belongs to category 2 in the GIA grading system. Type 2 means that natural alexandrite unlike lab-grown alexandrite almost always has many inclusions. Therefore, clean stones are extremely rare and command great premium prices. THE CENTER ALEXANDRITE IS ONE OF THE LARGEST AND MOST VALUABLE GEMSTONES WE HAVE SEEN IN MANY YEARS. Most people will go their whole lives without ever seeing an alexandrite of such size and quality.   The color change can be easily observed not only in candlelight but in any incandescent light like any yellow low-watt electric lamp's light. The stone easily changes color from bluish-green to gorgeous pinkish lavender purple, which makes it a rare collector's gem.
