In today's market, where the vast majority of sapphires are routinely heat-treated to enhance color and clarity, an unheated Ceylon sapphire of this size is a genuine rarity.

Their legendary status comes from the low-iron geology of Sri Lanka's alluvial deposits, which produces a characteristic cornflower-to-velvety-blue saturation with extraordinary transparency — that coveted \"lit from within\" luminosity. Unheated stones of this caliber command significant premiums at auction, and fine examples increasingly appear in major estate and collector sales. Some of the world's most celebrated sapphires — including the stone in Princess Diana's engagement ring — are Sri Lankan.\u003c\/p\u003e\n\u003cp class=\"p1\"\u003e\u003cb\u003eMetal:\u003c\/b\u003e 18k black rhodium white gold \u0026amp; 18k yellow gold\u003cbr\u003e\u003cb\u003eFinger Size:\u003c\/b\u003e 5.75\u003cbr\u003e\u003cb\u003eGemstone: \u003c\/b\u003eEarth mined\u003cbr\u003e\u003cb\u003eCut: \u003c\/b\u003eAntique cushion cut formerly Ceylon origin\u003cbr\u003e\u003cb\u003eWeight:\u003c\/b\u003e 3.70 ct\u003cbr\u003e\u003cb\u003eColor:\u003c\/b\u003e Violetish Blue \/ GemGuide Grading: 7.5PB 3\/10 #7\u003cbr\u003e\u003cb\u003eClarity:\u003c\/b\u003e Eye clean\u003cbr\u003e\u003cb\u003eMeasurements:\u003c\/b\u003e 8.58 x 7.28 x 6.16 mm\u003cbr\u003eGIA Laboratory No. \u003ca rel=\"noopener\" title=\"GIA Lab Report 6234347881\" href=\"https:\/\/www.gia.edu\/report-check?locale=en_US\u0026amp;reportno=6234347881\" target=\"_blank\"\u003e6234347881\u003c\/a\u003e\u003cbr\u003e\u003cb\u003eDiamonds:\u003c\/b\u003e 2 = J\/K SI1-3\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003eThis is not a ring you encounter often.
