After researching where to buy authentic moldavite, I found a few reliable sources that delivered genuine pieces. I have personally bought from czechmoldavite.com multiple times and can confirm their stones are real. The same person also runs moldavitstore.com, which is equally trustworthy. Another good option is the eBay seller czechminerals, who is based in the Czech Republic like the others. These sellers are risk-free and I recommend sticking to them. Be careful with other sellers, especially those located in Asia, as there is a high chance of receiving fake stones. Moldavite set in jewelry or sold as cut gems also has a greater risk of being counterfeit. Shipping from the Czech Republic to the U.S. can take one to two weeks, since they use budget shipping methods, so plan for that. Prices for moldavite are increasing, so if you are considering a purchase, it is best not to wait too long.
