This 1ct natural purple sapphire presents a rich, saturated purple hue that sets it apart from the more common pink and blue sapphire varieties. Cut into an elegant heart shape with generous 7.17 x 5.77 mm proportions, it delivers strong visual presence well beyond what its carat weight suggests.
What makes this stone exceptional is its unheated status. This sapphire has not undergone any heat treatment, preserving its natural colour exactly as formed deep within the earth. Unheated Ceylon sapphires command a premium for their rarity. Fewer than 5% of sapphires reach the market without treatment.
Origin & Certification
This sapphire originates from Ceylon (Sri Lanka), the island that has produced some of the world's most celebrated coloured gemstones for millennia. Ceylon is particularly renowned for its purple and violet sapphires, which owe their colour to trace amounts of vanadium and chromium in the crystal structure.
The Colored Stone Laboratory (CSL) has examined this sapphire and confirmed its natural origin, unheated status, and purple colour on the accompanying certificate. CSL is a respected independent gemological laboratory, and their report provides buyers with confidence in the stone's authenticity and treatment disclosure.
Why This Purple Sapphire
Purple sapphires occupy a rare middle ground in the sapphire family. Less common than blue, more unusual than pink, and increasingly sought after by collectors who value distinctive colour. This stone's heart shape adds romantic appeal, making it a compelling choice for an engagement ring, anniversary pendant, or statement piece.
At $650 AUD for a 1ct unheated Ceylon sapphire, this stone represents genuine collector-grade value. Comparable unheated purple sapphires from Ceylon routinely sell for significantly more at auction, particularly in heart and cushion cuts. The generous face-up dimensions (7.17 x 5.77 mm) mean this stone will look substantial in any setting.

Is this purple sapphire heated?
No. This sapphire is completely unheated and untreated. Its purple colour is entirely natural, as confirmed by the CSL certificate. Unheated sapphires are rare. Fewer than 5% of sapphires reach the market without heat treatment.
What is the difference between purple and pink sapphire?
Purple sapphires contain a higher concentration of vanadium, giving them a violet-to-purple hue rather than the pink tones caused primarily by chromium. Both are varieties of corundum, but purple sapphires are considerably rarer in unheated form.
Can a heart-shaped sapphire be set in a ring?
Yes. Heart-shaped sapphires make stunning solitaire rings and are popular for engagement rings. The 7.17 x 5.77 mm dimensions of this stone suit standard prong or bezel settings. Sapphires rate 9 on the Mohs hardness scale, making them ideal for daily wear.
