SIAMITE
Siamite® Gemstone Reflections is a premium brand for precision-cut gemstone imitations manufactured in a spectacular range of transparent, translucent and opaque colors, special effects, shapes and sizes to use for jewelry and fashion accessories.
​
Formerly known as Nanogem® and Nanocrystal®, the material has been rebranded as Siamite®, the name that is composed of its three main chemical components: Si, Al and Mg.
​
SIAMITE® made by Formica is in line with security standards for toys, safe landfill and safe textile products and with all of the regulations of REACH (EC) No 1907/2006 and in compliance with EU RoHS. All of the potentially toxic elements measured are within permissible limits.
Siamite® Gemstone Reflections is currently offered in 500 color options and wide ranges of saturation and shades, which allows to achieve consistent color within the product size range from 0.8mm to 30.00mm.
Siamite® is recognized for its unique physical and optical properties, such as close to zero thermal expansion and homogeneous composition which allows for even distribution of color throughout the material. One of key features of Siamite is its ability to withstand high temperatures. Siamite® only begins to melt or decompose at temperatures above 1,500°C, offering exceptional stability, when being set in jewelry using lost-wax casting.
​
And with it’s hardness approximating that of a topaz or emerald, and optical properties close to that of a tourmaline, Siamite® is an ideal gemstone imitation material eliminating common drawbacks of synthetic crystal, lead or zirconium glass, such as color zoning, excessively high refractive index and high cost.
