Comment: Here is a 'hunted' alexandrite just over one carat with a strong color change between a fresh apple green at day and an orange-reddish purple at night. As always with alexandrite, a complete 100% color-separation is not possible to capture in 'un-faked' images. Since this is in principal also true for the gem viewed in person, images like ours, that have not been photo-shopped into two colors, won't set-up the novice-buyer for a disappointing first date. Radically controlled artificial light-situations excluded, any natural light contains components of other wavelengths and hence any alexandrite mixes green-red-purple at the same time. Observing and separating these color-effects in person takes some time and patience but NO particular gem-know-how or even willingness. Wearing an alexandrite for some time in jewelry (which they take well, being tough and durable) guarantees AHA-effects when under new light-settings a new color glitters from your hand including the desired magic blue in the day-green. BTW: you won't see this if it glitters from your earrings and you look only into few mirrors but other will still be dazzleled. This 1.05 was hand-cut with respect to weight, managing to stay over the value-lifting one-carat-boundary without any flaws. My first lens-search brought up NO inclusions at all but then I picked up some disturbance in the sideimage (as so often, it was only in our images that I discover really tiny details). Another, then locally focused, search under the lens revealed an ever-so-delicate, thinner-than-thin, veil in the outer edge, meaning the gem is pratically 'free of inclusions'. A strong color-change, noted in a new lab-report from the 'Sri Lankan Gem Authority' (an incorruptible and highly qualified government institution), an almost lens-clean crystal, no treatments, good luster, shape and the magic one-plus carat, make the owner of this hunt a lucky buyer (as you can see from the relative low price, compared to other in this section, or on the market in general).
P.S. Start you own hunt here.
P.P.S. After almost two months of working with David Jerome's jewelry, it is a pleasure to grade a loose gem again; David's jewelry is stunning, but also terribly distracting for the gemologist.
