The main distinction is natural gems typically have inclusions from the crystallization process — gases and other minerals mixing during the molten stage of stone creation. Because lab-created stones rely on a steady, controlled process of applying minerals, heat and pressure, they usually have fewer inclusions.
How do you tell if a stone is lab created?
Lab-created gemstones are crystal-like; you can see ‘into’ and sometimes ‘through’ the gemstone. Lab-created gemstones have very vivid colors. Natural gemstones have opaque or diluted colors. Only the most expensive and rare natural gemstones exhibit the vivid colors of a lab-created gemstone.
How can you tell if a gemstone is natural or synthetic?
A natural gem is any gemstone that is entirely the product of nature. It’s unaltered by humans in any way, except for ordinary cutting and polishing. A synthetic gem is the same as a natural gem (in terms of physical, chemical and optical properties), EXCEPT that it has been made by humans.
Are lab created gemstones considered real?
Also referred to as “synthetic,” lab-created gemstones are in fact real and genuine; just man-made instead of mined from the earth. Believe it or not, lab gemstones are chemically, physically and optically identical to their natural counterparts!
How can you tell the difference between a lab created and natural sapphire?
For example, lab blue sapphire will always be a pure blue, without tint. On the other hand, natural sapphire can also be greenish blue or violet blue. And lab created sapphires are often flawless, whereas natural sapphires often have microscopic flaws (“inclusions”).
How can you tell the difference between a natural and synthetic ruby?
Chemical traces are left in the stone of a lab-created ruby and this is not seen in natural rubies. Minimal internal flaws, higher quality at a lower price and a larger ruby for the same price as a smaller one will tell you that it is synthetic.
How can you tell if a stone is real or fake?
While transparent and flawless gemstones are hard to find, look for any cracks, scratches, and black spots inside the gemstone before you zero in on your purchase. You can also consult a qualified gemologist to find out if the gem is natural or not.
How can I check my gemstone certificates?
Enter your gem testing certificate number on certificate issued gem testing laboratory’s website. If you found same certificate details on laboratory’s website, means this is original certificate and issued by that particular laboratory. It is very rare to match SAME WEIGHT any of two gemstones in the world.
Do lab created emeralds have value?
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. Nevertheless, a lab-created emerald isn’t nearly as valuable as a natural emerald.
Can tanzanite be lab created?
Firstly, whilst Tanzanite has never been successfully synthesized (a synthetic is a lab created, manmade version of the natural which has the same chemical and physical properties as a natural), a synthetic Forsterite has been produced in the last decade in Russia which produces an imitation which closely resembles …
Are all white sapphires lab created?
Natural white sapphire is very rare, so it’s safe to assume that all white sapphire jewelry seen in stores and online will be lab-created by gemologists. Sapphires and rubies were actually some of the first gemstones to by synthesized, or lab-grown. Sapphires have two ways of being synthesized: melting and solution.
How are lab created gems made?
There are two types of methods for artificially creating sapphires: melt processes, which involve melting aluminum oxide into a sapphire droplet, and solution processes, which grow sapphire crystals in a solution.
