Appearance & Cutting

The faceted cushion cut presents a broad rectangular outline with rounded corners. Its blue appearance varies across the stone and with the viewing angle, while the prominent visible inclusions create a distinctive internal pattern. Rich blue is a merchant visual description, not a laboratory color grade.

Clarity & Setting

This sapphire is semi-translucent with prominent inclusions visible without magnification. Those inclusions may affect suitability for a particular setting or process. A qualified jeweler should inspect the exact stone before setting, drilling, recutting, applying heat or using ultrasonic cleaning, and should use the stated measurements when planning the design.

Photos & Videos

All 13 product photographs and the video show this exact sapphire and were made in natural daylight. Color and apparent transparency can vary with lighting, viewing angle, surroundings and display settings; please review the complete gallery.

Report, Treatment & Origin

The sapphire is disclosed as heated only based on merchant records and examination. Its identification as natural sapphire, color, clarity and treatment disclosure are merchant assessments, not independent laboratory determinations. It was faceted at our gemstone-cutting facility in Bangkok, Thailand; this is the manufacturing and customs origin, not a mining-origin statement. Its geological origin has not been established.

No independent laboratory report is included. Identification as Natural sapphire, together with the color, clarity and treatment statements, is a qualified merchant assessment based on our records and examination, not a laboratory determination. An IGI report, or a report from another agreed local gemological laboratory, may be arranged before dispatch subject to service availability. Contact us before ordering to confirm the available laboratory, testing scope, current cost and turnaround time; this service will extend the dispatch time, and the laboratory may reach a different conclusion.
