{"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 that ranks 8.5 on the Mohs scale, making it one of the hardest natural gemstones available after diamond, \u003ca href=\"\/en-qa\/collections\/ruby-gemstones-loose-stones-gia-certification\"\u003eruby\u003c\/a\u003e, and \u003ca href=\"\/en-qa\/collections\/all-sapphire-gemstones\"\u003esapphire\u003c\/a\u003e.

Chrysoberyl is durable enough for daily wear, naturally untreated, and far less expensive than sapphire or ruby at comparable quality - making it one of the most compelling value propositions in natural gemstones for collectors and jewellery designers who know what they are looking at.\u003c\/p\u003e\n\n\u003ch2\u003eWhy Our Chrysoberyls\u003c\/h2\u003e\n\n\u003cp\u003eOur chrysoberyls are sourced from Sri Lanka, a leading source for fine natural chrysoberyl alongside Brazil and Myanmar.

The most prized stones show vivid yellow-green saturation with strong brilliance and no brownish modifier. Paler honey-yellow stones are softer and more wearable; deeper golden-greens are more striking. The color of fine chrysoberyl sits in a zone that no other major gemstone occupies - it is distinctly its own, not a substitute for anything else.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eClarity.\u003c\/strong\u003e Fine chrysoberyl is typically eye-clean with high transparency. We do not carry stones with significant visible inclusions. Its natural clarity is one of the reasons chrysoberyl is almost never treated - the rough is already good enough.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eCut.\u003c\/strong\u003e \u003ca href=\"\/en-qa\/collections\/oval-sapphire-engagement-ready-loose-stones\"\u003eOval\u003c\/a\u003e, \u003ca href=\"\/en-qa\/collections\/cushion-sapphires-vintage-style-loose-stones\"\u003ecushion\u003c\/a\u003e, and \u003ca href=\"\/en-qa\/collections\/round-sapphires-calibrated-loose-stones\"\u003eround\u003c\/a\u003e are the most common formats. \u003ca href=\"\/en-qa\/collections\/emerald-cut-sapphires-usa\"\u003eEmerald cuts\u003c\/a\u003e suit chrysoberyl's clarity beautifully - the open step facets reward the stone's natural transparency. Chrysoberyl's high refractive index (1.74-1.75, higher than sapphire at 1.76-1.77) produces strong brilliance in any well-executed cut.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eCarat.\u003c\/strong\u003e Chrysoberyl over 2 carats in fine color is accessible and reasonably priced. Above 5 carats in vivid yellowish-green begins to be genuinely scarce. Unlike sapphire, where price per carat rises sharply at the 1-carat mark, chrysoberyl pricing is more gradual - making larger stones a better value proposition relative to their size.\u003c\/p\u003e\n\n\u003ch2\u003eChrysoberyl vs Yellow Sapphire\u003c\/h2\u003e\n\n\u003cp\u003eBuyers comparing chrysoberyl to \u003ca href=\"\/en-qa\/collections\/yellow-sapphire-gemstones-unheated-ceylon-stones\"\u003eyellow sapphire\u003c\/a\u003e will find both are naturally untreated, both come from Sri Lanka, and both sit in the warm golden-yellow color zone. The key differences: sapphire (Mohs 9) is slightly harder than chrysoberyl (Mohs 8.5), sapphire carries more name recognition and commands higher prices, and the hue is distinctly different at the saturated end - chrysoberyl tends toward a more yellowish-green position while fine \u003ca href=\"\/en-qa\/collections\/unheated-yellow-sapphire-over-1-carat-natural-loose-stones\"\u003eyellow sapphire\u003c\/a\u003e is a purer canary yellow. For Jyotish (Vedic astrology) buyers, only yellow sapphire (Pukhraj) satisfies the Jupiter prescription - chrysoberyl does not qualify as a substitute.

Tsavorite (Mohs 7-7.5) is softer than chrysoberyl but produces more vivid, saturated green. Chrysoberyl tends toward a more muted, golden-green that reads warmer and more neutral. Both are genuinely untreated; both come from East Africa and Sri Lanka. The choice is aesthetic - tsavorite for vivid green, chrysoberyl for warm golden-green.\u003c\/p\u003e\n\n\u003ch2\u003eCat's Eye Chrysoberyl\u003c\/h2\u003e\n\n\u003cp\u003eCat's eye chrysoberyl shows chatoyancy - a sharp, single line of light that moves across the dome of a cabochon-cut stone as it is rotated, exactly like the slit pupil of a cat's eye under a torch. The finest cat's eyes show a strong, well-defined line over a vivid golden-green to honey-yellow body color, with a \"milk and honey\" effect - one side of the stone appearing creamy white as the light catches it. Cat's eye chrysoberyl is the most valuable variety of the species and one of the most collectible phenomenon gemstones in existence.
