{"title":"Natural Chrysoberyl - Loose Stones from Sri Lanka","description":"\u003cp\u003eChrysoberyl is one of the most underappreciated gem species in fine jewelry - a beryllium aluminum oxide, and a species entirely separate from beryl. Its color range runs from honey-yellow and golden-green through yellowish-green hues, and the species also includes the \u003ca href=\"\/en-jp\/collections\/alexandrite-gemstones-the-color-change-chrysoberyl\"\u003ealexandrite (color-change)\u003c\/a\u003e and cat's eye varieties.

Read more about our sourcing on our \u003ca href=\"\/en-jp\/about_us\"\u003eAbout page\u003c\/a\u003e.\u003c\/p\u003e\n\n\u003cp\u003ePremium pieces ship with \u003cstrong\u003eGIA reports\u003c\/strong\u003e. Each stone is photographed under standardized lighting against a neutral background, so the color you see online is as close as we can get it to the stone in your hand. On request we will send you a personal video of any individual stone.\u003c\/p\u003e\n\n\u003ch2\u003eWhat the GIA Reports on These Stones Do and Do Not Say\u003c\/h2\u003e\n\n\u003cp\u003eThe reports our chrysoberyls carry are a \u003cem\u003eCat's Eye Chrysoberyl Report\u003c\/em\u003e or an \u003cem\u003eIdentification Report\u003c\/em\u003e. Between them these documents print the item description, the weight, the measurements, the shape, the color, the transparency, the cutting style and - on the cat's eye stones - the phenomenon, together with a results box giving species and variety. On the cat's eye stones the phenomenon field reads \u003cstrong\u003eDisplaying Chatoyancy\u003c\/strong\u003e, which is GIA stating that the stone shows the effect; it is not a judgement of how sharp, how straight or how well centred the eye is, and GIA does not grade or quality-analyse coloured stones at all.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eNeither report type carries a treatment field, a geographic origin field, or a characteristics panel.\u003c\/strong\u003e So any statement about treatment, origin, hardness, refractive index or clarity on these pages is \u003cstrong\u003eours, not the laboratory's\u003c\/strong\u003e. We do not buy treated chrysoberyl, and where a stone's own listing says anything about treatment it says so as our statement. If that distinction matters to your purchase, ask us and we will tell you exactly what each document contains.\u003c\/p\u003e\n\n\u003ch2\u003eHow to Choose a Chrysoberyl\u003c\/h2\u003e\n\n\u003cp\u003e\u003cstrong\u003eHue.\u003c\/strong\u003e Faceted chrysoberyl typically appears in the golden-yellow through yellowish-green range. Paler honey-yellow stones read softer and wear easily; stones further toward green read warmer. The color of chrysoberyl sits in a zone that no other major gemstone occupies - it is distinctly its own, not a substitute for anything else. Which end of that range suits you is a matter of taste, and we do not rank them.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eClarity.\u003c\/strong\u003e We do not carry stones with inclusions that are obvious to the unaided eye. That is our own selection standard and our own description of what we sell - GIA issues no clarity grade for chrysoberyl, so there is no laboratory grade behind it.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eCut.\u003c\/strong\u003e \u003ca href=\"\/en-jp\/collections\/oval-sapphire-engagement-ready-loose-stones\"\u003eOval\u003c\/a\u003e, \u003ca href=\"\/en-jp\/collections\/cushion-sapphires-vintage-style-loose-stones\"\u003ecushion\u003c\/a\u003e and \u003ca href=\"\/en-jp\/collections\/round-sapphires-calibrated-loose-stones\"\u003eround\u003c\/a\u003e are the most common formats, and cat's eye material is cut as a cabochon so the effect can be seen. \u003ca href=\"\/en-jp\/collections\/emerald-cut-sapphires-usa\"\u003eEmerald cuts\u003c\/a\u003e suit chrysoberyl well - the open step facets give the stone's transparency somewhere to go.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eCarat.\u003c\/strong\u003e Larger stones in good color are available in this species. We quote no size threshold and no price multiple: each stone is priced individually, and its own listing carries its weight exactly as the report prints it.\u003c\/p\u003e\n\n\u003ch2\u003eChrysoberyl and Yellow Sapphire\u003c\/h2\u003e\n\n\u003cp\u003eBuyers comparing chrysoberyl to \u003ca href=\"\/en-jp\/collections\/yellow-sapphire-gemstones-ceylon-stones\"\u003eyellow sapphire\u003c\/a\u003e will find both in our Sri Lankan material, and both in the warm golden-yellow color zone. They are different species: the hue parts company in the deeper tones, where chrysoberyl runs more yellowish-green while \u003ca href=\"\/en-jp\/collections\/unheated-yellow-sapphire-over-1-carat-natural-loose-stones\"\u003eyellow sapphire\u003c\/a\u003e runs a purer yellow, and sapphire carries far more name recognition. Each stone's own listing states what its report says about treatment. If you are buying a yellow stone to meet a specific external specification - a jeweller's, a family tradition's, or an astrologer's - check that specification before choosing: it will usually name yellow sapphire, and chrysoberyl is a different species and will not satisfy it.\u003c\/p\u003e\n\n\u003ch2\u003eChrysoberyl and Tsavorite Garnet\u003c\/h2\u003e\n\n\u003cp\u003eFor buyers drawn to green-yellow gemstones, \u003ca href=\"\/en-jp\/collections\/tsavorite-garnet-gemstones-emerald-alternative\"\u003etsavorite garnet\u003c\/a\u003e is the other option in this color family. Tsavorite is a softer species and runs a cleaner green; chrysoberyl runs to a golden-green that reads warmer and more neutral. Both reach us from East Africa and Sri Lanka. The choice is aesthetic.\u003c\/p\u003e\n\n\u003ch2\u003eCat's Eye Chrysoberyl\u003c\/h2\u003e\n\n\u003cp\u003eCat's eye chrysoberyl shows chatoyancy: a band of light that moves across the dome of a cabochon as the stone is turned, like the slit pupil of a cat's eye under a torch. The mechanism is the stone's own structure - fine needle-like inclusions lying oriented parallel to the cabochon base reflect light back as a single band at right angles to themselves, which is why the cut has to follow the inclusions rather than the other way round. On the stones here that carry it, GIA's phenomenon field prints \u003cstrong\u003eDisplaying Chatoyancy\u003c\/strong\u003e; everything we then say about the band's appearance is our own description, because no laboratory publishes a quality scale for it. See our dedicated \u003ca href=\"\/en-jp\/collections\/natural-cats-eye-chrysoberyl-chatoyancy-stones\"\u003ecat's eye chrysoberyl collection\u003c\/a\u003e for available stones.\u003c\/p\u003e\n\n\u003ch2\u003eFor Collectors\u003c\/h2\u003e\n\n\u003cp\u003eChrysoberyl is a species that rewards looking at directly rather than reading about. If you already collect natural Sri Lankan gemstones alongside sapphire and ruby, it is a straightforward way into another species, and the stones here are individually photographed so you can judge them yourself. We make no claim about what any stone will be worth later, and we do not sell gemstones as a financial product.
