Czochralski Gems

Discover Gemdrop® Czochralski-grown gems: premium lab crystals created using the Czochralski method, in which a carefully controlled single crystal is pulled from molten material to maximize atomic structure and ordering, creating highly pure, optically beautiful gem material. Our collection includes Czochralski ruby, sapphire and other premium gems, selected for their premium colour, clarity and crystal quality and precision cut to maximise their optical performance. The advanced technology growth process produces just that extra bit of light diffraction and transmittance of light through the crystal lattive resulting in the maximum sparkle. Every gem is individually scientifically verified in the UK, permanently recorded in the Gemdrop® Verification Database, and protected by the Gemdrop® Lifetime Authenticity Guarantee.
