Experience the captivating beauty of this ~1.65 ct (6 × 8 mm) Oval Cut lab-grown colour-change corundum Alexandrite, displaying a striking purple-to-green colour change under different lighting conditions. This precision-cut gem combines outstanding brilliance with one of the most fascinating optical effects available in laboratory-grown gems.

This gem belongs to the corundum family (Al₂O₃), the same mineral species as ruby and sapphire. Although it displays an alexandrite-like colour change, it is not chrysoberyl alexandrite. At Gemdrop®, we distinguish the underlying mineral from its optical appearance, ensuring every gem is described accurately and transparently.

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 CORUNDUM. CREATED THROUGH SCIENCE.

This gem was grown using the Czochralski crystal growth process, producing a high-quality single crystal with exceptional clarity, colour consistency and optical performance. Through carefully controlled chemistry, trace elements within the crystal produce a dramatic colour change reminiscent of natural alexandrite while remaining a genuine member of the corundum family.

The resulting crystal is genuine laboratory-grown corundum—not glass or cubic zirconia—and possesses the same physical, chemical and optical properties expected of synthetic sapphire.

ALEXANDRITE-LIKE COLOUR CHANGE. EXCEPTIONAL BRILLIANCE.

Under cool daylight, this gem displays vibrant green tones. Under warm indoor or incandescent lighting, it transforms to beautiful purple hues, creating an eye-catching colour-changing effect that makes every viewing experience unique.

The Oval Cut is one of the most timeless and versatile gem cuts, combining elegant proportions with exceptional brilliance while beautifully showcasing the gem's remarkable colour-changing effect. It is an outstanding choice for rings, pendants, earrings and bespoke jewellery.

With a Mohs hardness of 9, corundum is one of the world's most durable gem materials, making it exceptionally well suited to jewellery intended for everyday wear.
