~3.5ct London Blue Spinel | Heart Cut | 10 × 10 mm | Gemdrop® Verified

Experience the captivating beauty of this ~3.5 carat (10 × 10 mm) Heart Cut lab-grown London Blue spinel. Displaying a deep, sophisticated blue inspired by the finest London Blue topaz, this precision-cut gem combines exceptional brilliance with the durability and outstanding optical performance of genuine spinel.

Lab-grown spinels are real spinels. They possess the same chemical composition (MgAl₂O₄), crystal structure, hardness, and optical properties as natural spinel. The only difference is their origin.

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 SPINEL. CREATED THROUGH SCIENCE.

This gem was grown using the Flame Fusion (Verneuil) process, a well-established technique for producing gem-quality spinel 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 spinel crystals with exceptional optical quality, colour consistency, and clarity.

The resulting crystal is genuine spinel—not a simulant or imitation—with the same physical, chemical, and optical properties as spinel formed naturally within the Earth.

LONDON BLUE. TIMELESS ELEGANCE.

London Blue spinel displays a rich, velvety blue with subtle teal undertones, creating a refined and contemporary appearance. The Heart Cut maximises brilliance and fire while highlighting the gem's elegant colour, making it an exceptional choice for rings, pendants, earrings and bespoke jewellery.

With a Mohs hardness of 8, spinel offers excellent durability for everyday jewellery while maintaining exceptional brilliance and polish.
