This 2.55ct unheated Ceylon pink sapphire is a striking stone that radiates a vivid, saturated pink from every angle. The radiant mixed cut. With its cropped corners and brilliant-style faceting. Maximises light return across the near-square 8.20 x 7.26 mm face, producing exceptional brilliance and scintillation that few pink gemstones can rival.
This stone has not undergone any heat treatment, preserving its vivid pink colour exactly as formed in the earth. Unheated Ceylon pink sapphires command a significant premium. Fewer than 5% of sapphires reach the market without treatment, and vivid specimens in this size range are particularly scarce.
Origin & Certification
This sapphire originates from Ceylon (Sri Lanka), the world’s most celebrated source of fine pink sapphires. The island’s unique geological conditions. Gem-bearing alluvial gravels formed over hundreds of millions of years. Produce pink sapphires with a warmth and saturation that distinguishes them from stones sourced elsewhere. Ceylon pink sapphires owe their colour to trace amounts of chromium in the corundum crystal, and the best examples display the vivid, evenly distributed pink seen in this stone.
The Ceylon Gem Lab (CGL) has examined this sapphire and issued a comprehensive certificate confirming its natural origin, unheated status, vivid pink colour, and 2.55-carat weight. CGL is one of Sri Lanka’s premier gemological laboratories, and their certification carries significant weight in the international coloured gemstone market.
The unheated status of this stone is particularly noteworthy. Heat treatment is the most common enhancement applied to sapphires and can improve colour and clarity. But it also means the final colour is partly artificial. An unheated sapphire with this level of vivid pink saturation demonstrates exceptional natural crystal quality. CGL has independently verified that no treatment of any kind has been applied.
Why This Pink Sapphire
At $5,000 AUD, this 2.55ct unheated Ceylon pink sapphire sits at the intersection of collector appeal and investment-grade rarity. Pink sapphires have seen sustained demand growth over the past decade, driven by their popularity as engagement ring centre stones and their increasing recognition as a serious alternative to pink diamonds. At a fraction of the price.
The radiant cut is an inspired choice for this stone. Unlike ovals or cushions, the radiant’s geometric facet pattern creates bold flashes of light that amplify the vivid pink colour. The near-square proportions (8.20 x 7.26 mm) provide excellent finger coverage in a ring setting, while the cropped corners add architectural interest and reduce the risk of chipping, a practical advantage for a stone destined for daily wear.
For buyers considering a pink sapphire engagement ring, this stone offers a rare combination: over 2.5 carats, vivid natural colour, unheated certification from a respected lab, and the prestige of Ceylon origin. These attributes together place it in a category that appreciates in value over time. Comparable unheated vivid pink sapphires from Ceylon regularly achieve strong results at international gemstone auctions.
Stones over 2 carats are significantly rarer than sub-carat specimens, and the jump in per-carat pricing at the 2-carat threshold reflects genuine scarcity. This is a stone that will hold its place in any serious gemstone portfolio.

Is this pink sapphire heated or unheated?
This sapphire is completely unheated. No heat treatment or any other enhancement has been applied. The vivid pink colour is entirely natural, as independently verified by the Ceylon Gem Lab (CGL) certificate. Unheated pink sapphires of this size and colour intensity are rare. Fewer than 5% of sapphires reach the market without treatment.
Why are unheated pink sapphires more valuable?
Unheated sapphires are valued because their colour and clarity are entirely the product of nature. Heat treatment can improve a stone’s appearance, but collectors and investors prize the rarity of a sapphire that achieves vivid colour without any human intervention. Unheated certification from a recognised lab like CGL adds transparency and supports long-term value retention.
Is a radiant cut sapphire good for an engagement ring?
Radiant cut sapphires are excellent for engagement rings. The brilliant-style faceting creates strong light return and sparkle, while the cropped corners reduce the risk of chipping during daily wear. The 8.20 x 7.26 mm dimensions of this stone make it a substantial centre stone suitable for solitaire, halo, and three-stone settings. Sapphires rate 9 on the Mohs hardness scale, second only to diamond.
