Alexandrite (BeAl2O4:Cr3+ ) is first-class precious stone, one of the hardest and longliving jewels (only diamond, sapphire and ruby stay before).

The most marvellous property of this gem is its ability to change color in accordance with source of lightening. Alexandrite becomes green like emerald in daylight, artificial lightening makes this magic stone purple-red. We possess the perfectly developed technology of Alexandrite obtaining.

Our Alexandrite is the complete analog of naturally occurring one. We can manage purposefully not only the color but subtle shades and color nuances. More than 20 years we have been delivering high quality Alexandrite crystals to USA, South-Eastern Asia and other international markets.
