*******************************************-

Our furnaces have European sertificate of quality CE.

 Sapphire, raised in our furnaces have stable phisic charcteristics : high level of purity and homogeneity, low density of dislocation (lower than ***0 pcs/sm), low inner intensity, mass from *0 up to **0 kgs.

Also we providing teaching, technological support for specialists of growing crystals in our production site.
