Buying a loose gemstone gives you independence, you get the freedom to make your own choice, your own jewelry design.
A natural 0.86 carat pink sapphire in a rectangular cushion shape with Mixed Cut faceting, from Sri Lanka (Ceylon), heat-treated and certified by GIC (Gemmological Institute of Colombo), Report #CrG0005-M. This vivid purplish pink hue combined with the elongated rectangular cushion outline gives the stone a distinctive, elegant profile that sets it apart from standard round or square cushion pink sapphires.
Expert Opinion
Ahmed Shareek's Assessment
"This 0.86 ct rectangular cushion sapphire shows exactly the kind of vivid, saturated purplish pink that makes fine Ceylon pink sapphires stand out from the more common, lighter pink material on the market. The heat treatment here is disclosed and standard practice in the trade, and the GIC report — issued by Sri Lanka's own gemological institute, working with material sourced right where it's mined — gives buyers clear, independent documentation of the stone's color and treatment status."
Rarity Analysis
A handful of factors combine on this stone to put it above the average pink sapphire you'll find at this size and price point.
-
Color: purplish pink is a distinct, more saturated variant of pink sapphire
-
Size: 0.86 ct is a practical, wearable size — large enough to read clearly as a center stone in a ring or pendant, without the steep price jump that comes with crossing the one-carat mark
-
Treatment: heated — standard, disclosed
-
Clarity: Eye Clean, with no visible inclusions under normal viewing — a meaningful mark of quality for a heated sapphire in this size range
-
Documentation: GIC Report #CrG0005-M — GIC (Gemmological Institute of Colombo) is a Sri Lanka-based gemological laboratory. The GIC report documents this stone's color, treatment, and dimensions; the Sri Lanka (Ceylon) origin stated for this stone reflects the seller's sourcing information rather than a formal origin determination on the report itself
-
Combined effect: a saturated purplish pink hue, an elongated rectangular cushion silhouette that few cutters attempt, and independent GIC documentation together make this a stone that reads as distinctive rather than standard-issue
Buying Guidance
A few things are worth keeping in mind if you're weighing this 0.86 ct purplish pink sapphire against other options.
-
Judge the color in person if you can: purplish pink sapphire photographs differently under different lighting, so cross-reference photos against the GIC report's color description before deciding
-
Treatment is not a concern here: heat treatment is stable, permanent, and disclosed — it is the industry-standard enhancement for the vast majority of fine sapphires sold today
-
Keep the GIC report with the stone: Report #CrG0005-M is the stone's permanent record of identity, color, and treatment, and should stay with it through any resetting or resale
-
Think about the setting early: the elongated rectangular cushion outline suits both prong and bezel settings differently than a standard square cushion, so it's worth discussing with a jeweler before committing to a design
-
Try Before You Buy: if you're deciding between this stone and other loose sapphires, compare them side by side in natural daylight as well as indoor lighting — saturated purplish pink hues like this one can shift noticeably between light sources

Why Choose this 0.86 ct Heated Rectangular Cushion Pink Sapphire?
Ceylon pink sapphire in this saturated purplish pink tone is prized for its vibrancy and warmth. The rectangular cushion cut elongates the face-up profile, giving the stone a more dramatic presence than a standard cushion shape of the same weight, while the Mixed Cut faceting maximizes brightness and fire. Heat treatment — disclosed transparently and confirmed by GIC Report #CrG0005-M — is a widely accepted, permanent enhancement in the sapphire trade that improves clarity and color consistency.

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 GIC 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. Heat treatment is stable and permanent under normal wear conditions.
