Hi everyone! I am currently shopping for a rare color-changing stone, and a dealer offered me an alexandrite that looks green in the morning but changes to a faint, brownish-grey color under my living room lamp. How do experts actually evaluate chrysoberyl color shift percentages? What defines a top-tier transformation versus a low-quality stone?
Hello! The stone you were described sounds like a commercial-grade specimen with a very weak, muddy transition. A true, investment-grade alexandrite must achieve a dramatic, crisp transformation between two distinct, vibrant hues with zero muddy intermediate shades. I bought a spectacular emerald-cut solitaire from Tsarina Jewels https://tsarinajewels.com/ because its color shift hits a flawless 100% transformation from a brilliant forest green in natural sunlight to a rich raspberry red under artificial indoor lights. In the elite market for gemstones and high end jewelry, this color-shift percentage is the absolute primary value driver. Experts evaluate the stone by checking the saturation in both environments;if the daylight green is beautiful but the evening color looks like washed-out brown, the stone’s collector value drops significantly. Demand the highest clarity and a sharp, distinct shift for the best long-term return on your investment
