The heart mixed cut is a romantic and distinctive choice, and at 9.12 × 8.31 mm, this stone offers exceptional face-up coverage that commands attention from across a room.\u003c\/p\u003e\n\n\u003cp\u003eThis stone has not undergone any heat treatment, preserving its natural colour as formed in the earth. Unheated Ceylon yellow sapphires over 3 carats are scarce. Fewer than 10% of yellow sapphires reach the market without treatment, and the percentage shrinks dramatically above 2 carats.\u003c\/p\u003e\n\n\u003ch2\u003eOrigin \u0026amp; Certification\u003c\/h2\u003e\n\n\u003cp\u003eThis sapphire originates from Ceylon (Sri Lanka), the island renowned for producing the world's finest yellow sapphires. Ceylon's alluvial deposits yield yellow sapphires with distinctive colour purity. Clean, saturated yellows free of the greenish or brownish modifiers common in other origins.\u003c\/p\u003e\n\n\u003cp\u003eThe Ceylon Gem Lab (CGL) has examined this sapphire and confirmed its natural origin, unheated status, and intense yellow colour on the accompanying certificate. CGL's unheated certification provides authoritative assurance that this stone's colour is entirely natural.\u003c\/p\u003e\n\n\u003ch2\u003eWhy This Heart-Cut Yellow Sapphire\u003c\/h2\u003e\n\n\u003cp\u003eThe heart cut sets this stone apart from the rectangular and cushion shapes that dominate the yellow sapphire market. Heart-cut sapphires are rarely offered in unheated material above 3 carats, making this stone a genuine rarity. The shape carries inherent romantic symbolism, which makes it an extraordinary choice for an engagement ring or anniversary gift with deeply personal meaning.\u003c\/p\u003e\n\n\u003cp\u003eAt $3,500 AUD, this 3.17ct unheated yellow sapphire represents rare natural colour at a compelling value. Most large unheated yellows are cut as ovals or cushions to maximise weight retention, a heart cut at this size is a deliberate investment in beauty. The generous 9.12 × 8.31 mm dimensions suit a bold solitaire ring or statement pendant, and sapphire's 9\/10 Mohs hardness ensures it will withstand daily wear for generations.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eRelated:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\u003ca href=\"\/collections\/yellow-sapphire\"\u003eBrowse our full Ceylon Yellow Sapphire collection\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"\/products\/ceylon-yellow-sapphire-3-03ct-radiant-unheated\"\u003eCompare: 3.03ct Unheated Yellow Sapphire Radiant\u003c\/a\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cdetails\u003e\n\u003csummary\u003eIs this yellow sapphire heated?\u003c\/summary\u003e\n\u003cp\u003eNo. This sapphire is completely unheated and untreated.
