What is a lab treated emerald?
Answer: A lab-created emerald is a real emerald but not a natural emerald. Synthetic emeralds are some of the most expensive synthetic gems. The methods used to create them in labs require expensive equipment. The process is slow and energy intensive, and the yield of facetable material is low.
Is a simulated emerald real?
For example, synthetic emeralds may be real emeralds but not natural emeralds. Depending on the process used, synthetic gemstones may even have the same inclusions and flaws found in natural gems. Gemstones synthesized in a lab that simply imitate natural stones are called simulated gemstones or simulants.
How can you tell if a emerald is lab created?
A genuine emerald does not sparkle with fire, as do gemstones such as diamonds, moissanite or peridot. If you hold up an emerald to a source of light, it will shine but with a dull fire. There will be no rainbow flashes emitting from the stone. If the stone does sparkle and have intense fire, it is likely a fake.
What is natural emerald?
Emerald is a green variety of the mineral beryllium. Unlike diamonds, which have their own grading system, natural emeralds are considered one of the top precious stones with an ancient pedigree and are valued in a distinctly different way.
Do Lab created emeralds have flaws?
Natural emeralds almost always contain more inclusions, or visual variations due to minerals within the gemstone, than other colored stones. Lab created emeralds or lab grown emeralds differ in color and contain no inclusions. Some view this as preferable, as inclusions can be seen as flaws.
How can I test my emerald stone at home?
Examine the gem under magnification, ideally through a 10x triple-lens jeweler’s loupe. Hold it so light strikes it at an oblique angle, in one narrow beam if possible. If you see tiny flaws or irregular patterns within the stone, it is likely a real gem — although not necessarily an emerald.
Why are gemstones grown in a Chatham lab?
Chatham gemstones are known for their superior quality thanks to the continuous technical refinement over our 80-year history. By duplicating the conditions deep within the Earth, including temperature, pressure and chemical makeup, our laboratory can grow gemstones over a year’s time.
Is there a diffusion treatment for Star Sapphire?
Diffusion treatment is a popular method for treating star sapphire, since the treatment will increase the asterism (the star effect in sapphire and ruby). The diffusion process may reach a depth of half a millimeter into the gemstone.
What does diffusion treatment do to a stone?
Diffusion Treatment. Diffusion treatment consists of exposing the surface of a stone to certain chemicals combined with high heat in a furnace. Generally, only the surface color changes, so if you sliced the gem in half, the inside of the stone would be a different color, usually a paler, less valuable color.
