Preciosa Nanogems, The Alpha Round Brilliant, 1mm, Tanzanite

Description

Preciosa Cubic Zirconia & Gems are cut exclusively from synthetic crystals of the highest quality.

Virtually indistinguishable from their natural counterparts, Preciosa Nanogems are more uniform in colour and nothing is closer in hardness, refractive index, and lustre.

They completely imitate their gemstone counterparts in colour, brightness, hardness and density.

Unlike glass and many other synthetic stones, Preciosa Nanogems are stable and practically indestructible. They will never fade, change colour, or be damaged during secondary processing, such as casting.

Nanogems high thermal shock resistance makes these tiny stones ideal for the lost wax casting process. They are also resistant to acids, bases and humidity.

These Nanogems are in the ‘Alpha Round Brilliant’ cut, a re-imagined round cut, which achieves the most ideal ratio of brilliance, scintillation and fire ever exemplified by round-cut cubic zirconia.

The ‘Alpha’ cut includes a microscopic laser engraved Preciosa logo as proof of origin and authenticity.

In the colour ‘Tanzanite’, these stones display a dazzling royal blue sparkle, that will never change or fade.

These gems measure 1mm in size and are sold individually.

Preciosa Nanogems have a hardness of 7-7.5 on the Mohs scale and heat resistance of up to 1,100 °C/2,012 °F.

Preciosa fine jewelry stones, both synthetic and genuine, are responsibly sourced, fully produced in the Czech Republic and individually cut and polished to stunning perfection.
