Natural Alexandrite by Multicolour.com |
The ideal alexandrite is one with a medium tone and intense or near vivid color, blue-green in daylight to rich ruby red or purple red under incandescent light or candlelight. Alexandrites that bleed, or those in which one can see the two colors at the same time may be less desirable but since light sources are often mixed anyway, the phenomena is quite common. Grayish and brownish tones are common in many alexandrites and these stones are considered to be less valuable. A fine stone displays a distinct and dramatic color change where both colors are bright and attractive.
