The internet is an incredible resource, but also one filled with many pitfalls, and is quite the maze when it comes to natural, untreated, therapeutic gemstones. If you are looking to work with any gemstone or crystal for therapeutic or spiritual use, quality is the most important factor, and there are very few companies out there I would recommend.
Many people find Gemaceuticals or other gemstone companies through referral, which is the best source of information as it comes directly from a friend or loved one. Social media is a wonderful place to find local gemstone companies and small businesses, however, many are just starting out and I have personally seen dozens of errors from other companies selling therapeutic gemstones regarding the gemstone not showing treatment disclosures or selling the wrong gemstone entirely. I recall looking at a new crystal healing company I found on Instagram, offering Rhodonite and calling it Rhodochrosite. This might seem like a small mistake because they sound similar, but their entire crystal structure, where they are mined, mineral makeup, and energetic frequency is very different. Many gemstones sometimes share similar mineral inclusions of color, such as Manganese in Rhodonite and Rhodochrosite, however, this company is doing a disservice to anyone seeking authentic, untreated, therapeutic gemstones. There are simply too many mistakes and errors currently out there from companies selling gemstones which are named incorrectly, have imitation gemstones still expressing the same claims of therapeutic effects and so forth.
