Buying a loose gemstone gives you independence, you get the freedom to make your own choice, your own jewelry design.
1.05 carat rectangle cushion-cut pink sapphire, heat-treated, measuring 6.60 × 4.43 × 4.04 mm. Pink sapphire is natural corundum colored by chromium — the same element responsible for red in ruby, present in lower concentrations that produce pink rather than red. Accompanied by AGCL Report #M256725 confirming weight, color, shape, cut, dimensions, and treatment.
Expert Opinion
Ahmed Shareek's Assessment
"This 1.05 ct pink sapphire shows the warm, even color that heat treatment reliably brings out in corundum — heating is standard practice across the vast majority of sapphires on the market and is fully disclosed here on the AGCL report. At just over a carat in a clean rectangular cushion cut, it's a practical, wearable center-stone size without stepping into rare, high-premium territory. What's stated on the lab report is exactly what you're getting — no surprises."
Rarity Analysis
Rarity in colored gemstones comes down to a combination of factors working together, not any single trait alone. Here's how this pink sapphire's characteristics stack up:
-
Color: Pink sapphire owes its hue to trace chromium in the corundum structure — the same element behind ruby's red — making it a distinct, sought-after member of the sapphire family rather than a byproduct color.
-
Size: At 1.05 carats, this stone sits just above the 1-carat mark, a size threshold that carries a meaningful price step-up over smaller melee-range pink sapphires while remaining accessible.
-
Treatment: heated — standard, disclosed. The vast majority of sapphires on the market today are heat-treated to improve color and clarity, and this is confirmed on the AGCL report.
-
Clarity: Slightly Included — note honestly: minor inclusions are visible under magnification and may be visible to the unaided eye depending on lighting and angle; this is typical for the grade and not indicative of a lesser stone.
-
Documentation: AGCL Report #M256725; note origin is not addressed or stated for this stone.
-
Combined effect: A documented, disclosed-treatment pink sapphire at a practical center-stone size represents a solid, honestly-presented value rather than a rare outlier — the kind of stone well-suited to everyday fine jewelry.
Buying Guidance
A few practical points to consider before purchasing this pink sapphire:
-
Setting Choice: A rectangular cushion cut pairs well with classic four-prong or bezel settings that protect the corners, which are more vulnerable to chipping than rounded shapes.
-
Color in Different Light: Pink sapphire can shift subtly in tone between daylight and indoor lighting; viewing the stone (or its video) under multiple light sources before committing is recommended.
-
Documentation Review: Request and review the AGCL Report #M256725 directly to confirm the treatment and grading details match what's described here.
-
Budget Fit: At $840, this stone offers a documented, heat-treated pink sapphire at a reasonable price point for a center stone just over 1 carat.
-
Try Before You Buy: Crescent Gems offers a try-on option so you can see the stone in hand and in your own lighting before finalizing a purchase.
