SYTHETIC TREATMENT OF STAR BLUE SAPPHIRE

Blue sapphire are made by adding 0.1 to 0.3 percent TiO2 to the feed powder, the boule is grown in the normal way and then reheated to about 1300 degree Celsius

This causes the previously disseminated rutile to take up needle like forms in six at right angles to the vertical axis of the boule. Stones are cut with the cabochon top coinciding with the top of the boule. Stars in synthetic corundum are notably perfect with bright, even rays reaching the edge of the stone and backs are flat and smooth.

GLASS FILLED BLUE SAPPHIRE

Glass filling in blue sapphire was first observed in Thailand in 2007. In 2007 we found Cobalt colored sapphire in Chantaburi market.

The process of glass filling is the low grade blue sapphire and a high lead glass that induces blue coloration and enhances clarity. The result is a medium saturated blue color of sapphire.

These sapphires can easily identified by a Gemologist. These types of glass filled sapphires costs less than 10$ for 1 gm/5ct piece but almost 70% of jewellers are selling these types of sapphires with certification at high prices. Customers should demand a reputed lab (IGI, GIA, GRS etc) certification before buying blue sapphire.
