Appearance & Cutting

Broad step facets create structured reflections, while the two differently faceted faces give the stone a distinct presentation from either side. Depending on the light, background, viewing angle and selected face, its IGI-stated greenish-yellow color may appear more olive yellow or warmer golden yellow.

Clarity & Setting

We assess the sapphire as very slightly included; IGI records a natural inclusion pattern but does not assign a clarity grade. In a conventional setting, the jeweler selects one face to remain upward; a truly reversible finished jewel requires a purpose-designed setting. The stone's pointed ends and shallow 2.80 mm depth should be considered during setting design.

Photos & Videos

All product photographs, the IGI report photograph and both videos show this exact sapphire. The gallery shows both broad faces, angles and scale in natural daylight. Color and reflections can vary with lighting, viewing side, angle, surroundings and display settings; please review the complete gallery and IGI report before ordering.

Faceting, Treatment & Origin

IGI records indications of heating. Madagascar is based on our sourcing information and is not stated as geographic origin on the IGI report. The sapphire was faceted at our colored-gemstone cutting facility in Bangkok, Thailand.
