{"title":"GIA Certified Purple Sapphires - Lab-Verified Natural Star Sapphires","description":"\u003cp\u003ePurple sapphire is a rare and striking color in its own right, and every stone in this collection carries an added phenomenon: six-ray asterism, the star effect that appears as a moving light pattern across the dome of a cabochon-cut stone. Every piece here ships with a GIA identification or origin report, confirming the stone is natural corundum with treatment status disclosed plainly.\u003c\/p\u003e\n\n\u003ch2\u003eWhy GIA-certified purple\u003c\/h2\u003e\n\n\u003cp\u003ePurple sapphire is corundum colored by a combination of trace iron, titanium, and chromium, and star sapphire in particular relies on precisely oriented rutile inclusions to produce asterism — a combination rare enough that independent lab confirmation carries real weight. A GIA report confirms the stone is natural corundum, states whether it has been heat-treated, and for many pieces offers an origin opinion.\u003c\/p\u003e\n\n\u003ch2\u003eWhat to expect\u003c\/h2\u003e\n\n\u003cp\u003e\u003cstrong\u003eThe star.\u003c\/strong\u003e Look for a sharp, well-centered six-ray star that moves cleanly across the dome under a single light source — the sharper and more centered the star, the more desirable the stone.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eTreatment.\u003c\/strong\u003e Star sapphires in this collection are predominantly unheated, since heat treatment can affect asterism; treatment status is confirmed on the GIA report and stated plainly on every product page.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eCertification.\u003c\/strong\u003e Every stone here carries a GIA report; the issuing lab and report number are noted on the product page.\u003c\/p\u003e\n\n\u003ch2\u003eShop more phenomenal sapphire\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\u003ca href=\"\/ja\/collections\/natural-star-sapphires-six-ray-asterism-unheated-ceylon\"\u003eStar Sapphire\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"\/ja\/collections\/gia-certified-stones\"\u003eAll GIA Certified Stones\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"\/ja\/collections\/gia-certified-color-change-sapphires\"\u003eGIA Certified Color-Change Sapphires\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"\/ja\/collections\/all-sapphire-gemstones\"\u003eAll Sapphire (every color)\u003c\/a\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eLearn more\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\u003ca href=\"\/ja\/blogs\/information-pages-complete-guide\/what-is-a-gia-sapphire-report-and-how-do-you-read-one\"\u003eHow to Read a GIA Sapphire Report\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"\/ja\/blogs\/information-pages-complete-guide\/sapphire-buying-guide\"\u003eUltimate Sapphire Buying Guide\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"\/ja\/blogs\/information-pages-complete-guide\/what-is-an-unheated-sapphire\"\u003eWhat Is an Unheated Sapphire?\u003c\/a\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003eHave a question about a specific report or want help choosing?
