Alexandrite Ring Guide
Alexandrite changes from green in daylight to red-purple under warm light. This rare gemstone makes a unique engagement ring. Learn quality factors, lab created alternatives and custom options.
The Magic of Color Change in Alexandrite
Alexandrite is famous for its color change: green or teal in daylight, then raspberry red or purple under incandescent light. This phenomenon comes from chromium traces in the crystal. Natural alexandrite is extremely rare, so most buyers choose lab created alexandrite, which shows the same dramatic color change at a fraction of the price.
Alexandrite Quality Factors
When buying alexandrite, the color change is everything. The most valuable stones shift from a strong green to a vivid red-purple with high saturation in both lighting conditions. Size, clarity and cut also matter, but a dramatic color change outweighs minor inclusions.
| Factor | Best Choice | Notes |
|---|---|---|
| Color Change | Strong green to red-purple | Dominant price driver |
| Cut | Round, oval, cushion | Brilliant cuts show color best |
| Clarity | Eye-clean or minor inclusions | Lab created stones are clean |
| Carat | 1-2 carat popular | Natural above 3 ct is rare |
