Colored stone professionals assess fine alexandrites by the extent of the color change they display and by the quality of the red and green hues they show under different lighting conditions.

What To Look For
Alexandrites tend to contain few inclusions. There’s a dramatic rise in value for clean material with good color change and strong hues. Rarely parallel needle-like inclusions create a cat’s-eye phenomenon, increasing the alexandrite’s value.
Alexandrite Quality Factors: The Comprehensive Guide
Tips & Advice
1. If it seems too good to be true, it probably is.
Natural alexandrite is rare and valuable. An inexpensive gem with a strong red-green color change is likely to be a synthetic or simulant.
2. Work with a jeweler you trust.
Judging the quality of alexandrite requires expertise. Look for gemological credentials. A jeweler who knows and loves alexandrite will welcome the challenge to find one that’s right for you.
3. When in doubt, get a lab report.
For a significant purchase an independent laboratory report can confirm that the alexandrite you are buying is natural.
4. Don’t expect to be able to match alexandrites easily.
Creating pairs or suites of alexandrite for earrings, a three stone ring, or a necklace is very challenging. Matching size, shape, color, and color change is particularly difficult.
