SCIENTIFIC EXPERTISE

4. Shine bright like a diamond
YAG is a material that has long established
uses in the gemstone industry. Its versatility
as a diamond simulator with excellent
optical qualities makes it a key material in
the production of precision laser equipment
and jewelry.
Eksitonit YAG has a crystal lattice structure
similar to that of Garnet, measuring 8.5 on
the Mohs hardness scale, it offers high
durability similar to Sapphires and Rubies.
Its excellent optical qualities and high
durability make Eksitonit YAG ideal for
engineering the highest quality luxury
lighting.
Our innovative Eksitonit YAG gemstone guarantees your chandeliers will shine bright
like a diamond!

5. Less dust means brighter lights
Our scientists have found that chandeliers
are getting dimmer due to the effects of the
hard silicon oxide mineral particles found in
dust. These particles scratch the surface of
crystals and glass causing small cuts that
over time dulls the surface leaving a once
beautiful chandelier muted and difficult to
clean.
The hardness of Eksitonit is one of the main
advantages for its use in luxury lighting
products. At almost 1.5 points harder than
other crystals or glass, Eksitonit is highly
scratch resistant and less susceptible to
the effects of dust particles.
Eksitonit’s scratch resistant surface makes your chandeliers less susceptible to dust
particles
