5.38 Ct. Greenish Blue Spinel from Ceylon (Sri Lanka)

This transparent 5.38 carat cushion shape greenish blue spinel from Ceylon Sri Lanka measures 9.64 x 8.79 x 7.12 mm, and exhibits a mixed brilliant cut that combines a brilliant style crown with step influenced pavilion facets, producing a controlled balance of scintillation and broad flash. The dark color intensity yields a deep, saturated greenish blue that reads lively under daylight and rich under incandescent light, while the excellent polish and crisp facet junctions maximize return of light through the table. Clarity is evaluated as very slightly included at eye level, with only minor pinpoint inclusions and faint veil structures that do not interfere with transparency or brilliance, these inclusions add to natural character without compromising durability. No enhancement has been applied, so the stone presents its natural color and internal features, and it benefits from spinel properties such as a refractive index typically near 1.718 and a specific gravity around 3.6, which contribute to pleasing heft and a brilliant, lively appearance when well set. The cushion outline and the mixed brilliant scheme make this gem particularly responsive to precision cutting, the pavilion depth and crown angles in this specimen have been executed to favor both depth of color and light performance, resulting in harmonious balance between sparkle and color saturation, The Natural Gemstone Company offers this stone to connoisseurs who value provenance and uncompromised natural material.

For a custom piece the greenish blue tone pairs exceptionally well with both cool and warm palettes, depending on the desired visual effect. For maximum brilliance and contrast consider a classic white diamond halo and tapered baguette diamond shoulders in an F to G color, VS clarity grade, set in platinum or 18 karat white gold, this approach lifts the apparent tone and accentuates the gem s sparkle while preserving the spinel s rich hue. For a contrasting, modern composition use warm yellow sapphires or small two to three millimeter cognac diamonds set in 18 karat yellow gold which will introduce complementary warmth and make the greenish blue read more vibrant. For a tonal, nature inspired design select paired mint green tourmalines or tsavorite garnets as accent stones, set in a low profile four prong or rounded claw mounting that protects the cushion corners and exposes the table for optimal light entry. In bespoke settings consider mixed cut side stones to echo the center stone s mixed brilliant cut, and request tight bezel polish and secure prong shoulders for durability, The Natural Gemstone Company can advise on exact millimeter tolerances and compatibility with standard mounting gauges for a finished piece that balances technical execution with aesthetic impact.
