After searching the internet the other day and noticing how much fake Moldavite is flooding the market, I have decided to write up a small guide to Moldavite. I was thoroughly disturbed at how much fake Moldavite is being sold to unsuspecting buyers as the genuine real thing. After collecting and selling Moldavite now for a very long time, I am seeing so much fake Moldavite for the past couple years showing up at wholesale shows plus offered for sell on the internet and a great amount of it is from China or Thailand. Hopefully by writing this guide, it will help you distinguish the characteristics of spotting a real Moldavite from a fake.
Genuine Moldavite is a member of the tektite group, a glassy mixture of silicone dioxide, aluminum oxide and other metal oxides, with a hardness of 5.5 to 6. Moldavite's formation coincides with the crash of a large meteorite in what is now the Bohemian plateau of the Czech Republic, approximately 14.8 million years ago. It is only found in what is now called the Moldau River valley in the Czech Republic. The color of most specimens is a deep forest green, though some pieces are pale green and others, especially those from Moravia, are greenish brown.In rough form, it has a distinct rippled surface. It can be polished and faceted in jewelry, but unless it's of extremely rare gem quality, it will have inclusions of gas bubbles and other inclusions within the stone, which adds to the enchantment of the Moldavite.
As true genuine Moldavite is getting more rare and the price is going up, the counterfeiters are getting better at their craft. Some fakes are very convincing, especially when mounted in jewelry where the signs of seams are hidden. Some counterfeiters are even now creating a mold from an actual genuine piece of Moldavite and replicating the color and texture to almost close to perfection. The best way to catch this is by noticing the stone is flawless and the price asked, which is a very low price usually. If the price is too good to be true, most the time it is a sign of a possible fake. There are sellers demanding higher prices for these fakes also. If the Moldavite you are examining is bright vibrant green in color, you are most likely looking at a fake Moldavite that was produced by melting green glass bottles. Also, be aware that the larger the Moldavite, the higher the price, as most genuine Moldavite is sold by the gram. If the seller claims the stone was mined anywhere but the Moldau River valley in the Czech Republic, it is most definitively a fake. If the Moldavite looks really wet or shiny, like melted glass, you are more than likely looking at a fake Moldavite. Now, there are some sellers that state up front that their Moldavite is lab-created, created or synthetic, which is just green glass made and formed to look like Moldavite. Just be aware that if it states lab-created, created or synthetic, you are getting green glass or maybe worse. Some fake Moldavite on the market isn't even green, which is a true sign that it is definitely fake. Below I will include some pictures of real and fake Moldavite so that you may see the difference for yourself.
