What is NANOCRYSTAL® or NANOGEMS?
It is a Hybrid of Glass and Synthetic Minerals. We took the best properties from both materials and combine them together. From Glass: Even, Homogeneous Color in every stone. From Synthetic Minerals - Relatively Higher Hardness Index 7-7.5 MO'S, Density and not fragile properties in compare to regular Glass.
Can it be set in WAX Casting?
High thermal shock resistance makes Nanocrystal® ideally compatible with wax casting technology.
Yes, Absolutely all colors of Nanogems can be set in Wax Casting without any problem. If STANDARD procedures that usually followed in this process are considered.
What would be the Lab report, if I send it to Testing Laboratory?
Only 2-3 World known Laboratories in the World has the equipment to trace nanosized 10⁻⁹ crystals of created Spinel, Sapphirine and other synthetic minerals inside of this material. These crystals are the ones that give this material special specific properties. Regular Laboratory will simply identify it as Regular Artificial Glass. Which is not exactly correct. Because we can provide Laboratory Research Report conducted by GIA (USA) published in Gems & Gemology Magazine in 2010.
There are many alternatives in the Market - Glass, Synthetic Quartz, Cubic Zirconia (CZ), Synthetic Corundum, Created Emerald...etc Why should I use Nanogems for big sizes and Fancy shapes, while I don't use Wax Casting?
Glass looks fake and is of low hardness, color also can fade away with time
Cubic Zirconia (CZ) has too high brilliance i.e. RI, which is why it's still the best affordable imitation of Natural Diamond. But it's not perfect for imitating Natural Color Stones... besides color is fading over time.
Synthetic Corundum and Created Materials - are too expensive... And it's not possible to cut really big sizes..due to limitation of rough size.
Nanocrystal® on the contrary completely imitates brightness and colors, as well as relatively close in hardness and density of many gemstones: Emerald, Sapphire, Topaz, Aquamarine, Citrine, Peridot, Garnet, Kunzite, Morganite, Grey and Smoky Quartz; Ivory (beige-cream), Turquoise, Aqua blue opal, Black and many others - totally more than 155 different colors and shades ...
Most of the Nanocrystals® are offered in different variations of color saturation: Very Dark, Dark, Medium and Light. The darker varieties are used for producing smaller sized stones, while the lighter selections are used for larger ones; this enables a manufacturer to maintain the same hue of color saturation throughout variations in sizes and shapes.
Does this material contain any hazardous elements?
Nanocrystal® - is 100% LEAD free material. It also complies with all EUROPEAN/USA Standards
All colors are compliant with these limitation:
We can provide Intertek or SGS Lab results if necessary to prove that Nanocrystal® is safe material to use
Nickel Release < 500 ppm
Cadmium < 75 ppm
Lead < 200 ppm
Arsenic < 25 ppm
Antimony < 60 ppm
Barium < 1,000 ppm
Chromium < 60 ppm
Mercury < 60 ppm
Selenium < 500 ppm
Radioactive - none
Benzedrine - none
Certain precautions must be taken, such as:
- Even though it's Wax Castable, better not over exposing this material to a Torch for a long time. Which is not regular Wax Casting Process.
- not over heating in the oven for too long (meaning 10th of hours and more).
Can you give more deep explanation and scientific information about Nanocrystal®
Nanogem or Nanocrystal®, which is another patented name of the same material, refers to a class of transparent glass-ceramics. Nanogems chemically are the high-temperature alumosilicates (the chemical composition is a mixture of oxides: SiO2, Al2O3, MgO, Li2O,…). This so-called hybrid material is composed of nanosized (about 10ˉ⁹ mm in dimensions) crystals of spinel, sapphirine, cordierite, garnet, quartz and other crystals that are homogeneously distributed in the amorphous matrix. These crystals also occur in nature and can therefore be called created nanosized crystals of naturally existing gemstones – Nanocrystals®, Nanogems or Nanogemstones. The analogue of the glass-ceramics in nature is obsidian, an effusive volcanic rock composed mainly of natural volcanic glass with abundant nucleation crystals (crystallites) and microlites.
