Rainbow Green Moissanite Cushion Cut Gemstone with GRA Certificate
$46.61
Descripción
Moissanite was first discovered in a meteorite crater. The material that occurs naturally is vanishingly rare — which is why the finest moissanite today is grown in controlled laboratory conditions that replicate and often surpass the optical properties of the original. This Rainbow Green Cushion Cut is one of the more unusual expressions of the material: a colour variant that shifts through green and spectral tones under different light conditions, producing a display that a white or near-colourless stone simply cannot replicate. The cushion cut — a rounded-corner square profile with large, open facets — is specifically chosen for coloured moissanite because it allows maximum light return through the body of the stone, which is where a coloured gem's character lives.
Each stone is GRA certified, with documentation confirming the stone's specifications, origin as a lab-created moissanite, and quality parameters. Available in eight sizes from 0.5ct (4.5x4.5mm) through 5.0ct (10x10mm), supplied as a loose stone ready for setting in a ring, pendant, earring, or any custom jewelry application. Moissanite rates 9.25 on the Mohs hardness scale — second only to diamond — which means it is appropriate for daily-wear jewelry without concern for surface scratching under normal conditions.
A coloured stone for those who understand that brilliance is not only a property of white gems.
Why This Gemstone
- Rainbow green colour — genuinely uncommon: Intrinsic to the crystal as grown, not a coating. Reads differently under daylight vs incandescent light.
- Cushion cut — chosen for coloured stones: Large open facets allow light through the body where a coloured gem's character lives.
- Lab created — consistent, traceable: No mining, no geographic variability, repeatable quality.
- GRA certificate included: Confirms carat weight, dimensions, quality grade. Required for custom jewelry sales.
- Mohs 9.25 — daily-wear appropriate: Second only to diamond. Will not scratch under normal conditions.
- Eight sizes — 0.5ct to 5.0ct: 4.5x4.5mm accent through 10x10mm statement centrepiece. Variant-level selection.
- Loose stone — any setting: Ring, pendant, earring, or custom application.
Who This Is For & How It Helps
Primary Buyer Profiles: Jewelry designers sourcing for custom commissions; buyers having a stone set locally; collectors; individuals seeking a coloured centrepiece for engagement, right-hand ring, or pendant.
Why Moissanite Over Other Coloured Stones: Higher refractive index (2.65 vs sapphire's 1.77) means more spectral colour in the flash — particularly effective in a stone that already carries body colour.
Size Selection Guidance: 0.5ct–1.0ct for accents and earrings. 1.5ct–2.0ct for ring and pendant centrepieces. 2.5ct–5.0ct for cocktail rings and large pendants. Always confirm millimetre dimensions against your setting's stone seat.
Working with the GRA Certificate: Present to your client as documentation of identity, origin, and specifications. Sufficient for most retail and custom jewelry applications.
