Buying a loose gemstone gives you independence, you get the freedom to make your own choice, your own jewelry design.
A natural 5.39 carat blue sapphire in a round shape with Mixed Cut faceting (Modified Brilliant crown, Step Cut pavilion), from Sri Lanka (Ceylon), completely unheated and certified by GIA, Report #5231646038. At 5.39 carats, this is an exceptional size for any sapphire; combined with unheated status and GIA documentation, it represents a genuinely rare specification — unheated Ceylon sapphires above 5 carats rarely appear at market.
Why Choose this 5.39 ct Unheated Ceylon Blue Sapphire?
The rarity of this stone comes from three combined factors: 5+ carats (size), unheated status (natural color), and GIA documentation (confirmed quality). At the 5+ carat level in unheated blue sapphire from Ceylon, each of these factors individually already narrows the available pool; together they represent a stone that will rarely appear at market again.

This 5.39 ct unheated Ceylon blue sapphire has been hand-selected as an exceptional specimen — the intersection of large size, natural treatment status, and independent documentation is the combination that defines the finest collector-grade sapphires.
One of a Kind
This is a single natural gemstone, not a manufactured or lab-created replica — no two sapphires form with identical color, clarity, and internal character. Once this stone sells, it's gone; there is no duplicate. What you see documented on the GIA report is the exact, individual stone you receive.
Care
Sapphire is exceptionally durable (Mohs 9), but a few habits keep it looking its best. Clean with warm water, mild soap, and a soft brush; avoid ultrasonic or steam cleaners if the stone is set alongside softer or treatment-sensitive materials. Store separately from other jewelry to prevent surface scratches to softer pieces, and remove the stone before swimming, exercising, or household chemical exposure. As an unheated stone, no thermal treatment stabilizes the color — normal wear is fine, but avoid sudden extreme temperature changes.
