Bluish green in daylight and purplish red under incandescent light, the color change is exceptional. Although there are some silky areas, the stone is quite clean and transparent. Slightly silky stones like this one often show a superior color change. The cutting, proportions and finish are good. Some minor windowing is observable but could easily be removed with a repolish. However, with a weight over 2.50cts., the stone may be worth more as it is and we’ve decided to leave it as it is for now. Alexandrites this large and nice are always hard to find and we buy them whenever we can get them at the right price.
