100% Color Change Natural Alexandrite Diamond Platinum Ring

  • Availability: In Stock
  • SKU: B19-112PT




The unique feature of this alexandrite is a 100% color change which is the main factor defining the value of this gemstone.

The stone is easily changing color from dark bluish green to gorgeous reddish purple, which makes it a rare collector's gem.

The color change is so STRONG that it can be easily observed not only in a candle light, but any incandescent light like any yellow low watt electric lamp's light. The alexandrite has a tiny inclusion coming to surface. It is certainly does not affect the durablility and overall beauty of the gemstone. Gemologists consider such mineral inclusions to be the proof of the natural origin of alexandrite.

Below are the quotes from GIA expert:
"Alexandrite is a Type II (GIA Clarity Grading System) stone and even the best natural alexandrite unlike lab grown alexandrite  is expected to contain many inclusions."
"An alexandrite of good clarity may display a less prominent color change because the silky inclusions of rutile often enhance the change. Some people prefer a weaker color change in favor of better clarity, but the color change should be the most important factor in determining the value of the stone."

GIA (Gemological Institute of America) is the highest world authority in diamonds and gemstones. Unlike other sellers, we never certify our jewelry because it is not ethical. We do not offer phony certificates. GIA certificate contains security features such as a hologram, security screen and microprint lines that prevent them from being forged or duplicated.
GIA certificate includes the colored picture of the item and the number of the certificate which can be verified online on GIA site. It is like a passport for the stone and will make it easier to sell it in the future (although we would advise against it because high-end alexandrites are becoming scarce and increase in price every year) and it can be used for insurance purposes as well.
