Displaying two distinct color zones within a single crystal, this is among the rarest color expressions in the sapphire family, far less common than single-color stones and highly prized by advanced collectors and gem connoisseurs alike.\u003c\/p\u003e\n\u003cp\u003eAt \u003cstrong\u003e66 carats\u003c\/strong\u003e, this crystal is extraordinarily large for a natural bicolor sapphire specimen. To put that in perspective, most fine sapphire crystals offered on the collector market weigh well under 10 carats — a 66-carat example with intact form and clean color zoning is a genuinely rare find that belongs in a serious collection or museum display.\u003c\/p\u003e\n\u003cp\u003eThe crystal structure is remarkable: well-formed hexagonal prismatic habit with clearly defined faces and sharp edges, a hallmark of gem-quality corundum growth under ideal geological conditions. Bicolor specimens of this structural integrity are extraordinarily difficult to source, as the zoning must develop cleanly without obscuring the crystal form.\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eBicolor sapphires develop their dual-tone appearance when shifts in trace element chemistry occur during crystal growth — a rare and precise geological event that cannot be replicated artificially in natural specimens.\u003c\/li\u003e\n\u003cli\u003eMadagascar is one of the world's premier sapphire-producing nations, yielding stones of exceptional clarity and color saturation.\u003c\/li\u003e\n\u003cli\u003eCorundum ranks 9 on the Mohs hardness scale, making this crystal as durable as it is beautiful — ideal for both display and study.\u003c\/li\u003e\n\u003cli\u003eLarge, naturally terminated sapphire crystals with distinct bicolor zoning are museum-caliber finds increasingly absent from the market.\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Juice Barr Gemz","offers":[{"title":"Default Title","offer_id":48821520236763,"sku":null,"price":669.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0827\/7924\/2715\/files\/IMG-2594.heic?v=1780099817","url":"https:\/\/juice-barr-gemz.myshopify.com\/products\/bicolor-sapphire-from-madagascar","provider":"Juice Barr Gemz","version":"1.0","type":"link"}
