~2.46ct Purple–Green Colour Change Corundum Alexandrite | Heart Cut | 8 × 8 mm | Gemdrop® Verified
Experience the captivating beauty of this ~2.46 ct (8 × 8 mm) Heart 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 Heart Cut combines exceptional brilliance with a timeless symbol of love and affection, beautifully showcasing the gem's remarkable colour-changing effect. Its elegant proportions make it a stunning choice for rings, pendants, earrings and meaningful 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.
