Every Gemdrop® gem is individually scientifically verified and permanently recorded within the Gemdrop Verification Database, providing complete transparency and confidence in exactly what you are purchasing.
A REAL SAPPHIRE. CREATED THROUGH SCIENCE.
This gem was grown using the Flame Fusion (Verneuil) process, a well-established technique for producing gem-quality corundum, within one of the world's leading high-technology gem-growing laboratories. Utilising advanced crystal growth systems and carefully controlled production conditions, these facilities produce sapphire crystals with exceptional optical quality, colour consistency, and clarity.
The resulting crystal is genuine sapphire—not a simulant or imitation—with the same physical, chemical, and optical properties as sapphire formed naturally within the Earth.
ELECTRIC COLOUR. UNMISTAKABLE PRESENCE.
Inspired by the vivid tropical blue-green hues associated with the famous Paraíba colour palette, this sapphire displays an exceptionally bright and energetic appearance. Brilliant turquoise, cyan, and subtle green tones combine to create a vibrant colour that stands out in any jewellery design.
The Cushion Cut maximises brilliance through its softly rounded outline and brilliant-style faceting, enhancing both sparkle and colour saturation. At approximately 21 carats, this impressive gem is ideal for statement rings, pendants, collector displays, and bespoke jewellery where exceptional colour takes centre stage.
With a Mohs hardness of 9, sapphire is one of the world's most durable gem materials, providing outstanding resistance to scratching and making it perfectly suited to jewellery intended for generations of enjoyment.
