***We warmly welcome your purchase of gemstone loose stones!*** However, if you'd like us to create jewelry for you, please feel free to ask. We've received many inquiries from those who have purchased gemstones as loose stones but are unsure where to have them made into jewelry. Therefore, we are now offering jewelry creation services on Mercari. If you purchase items from us, we will create a unique, comfortable-to-wear, one-of-a-kind piece of jewelry through full custom order, rather than using pre-made settings. *** "Today, I'd like to introduce a special gemstone!" ☆ October's Birthstone: Tourmaline "Beautiful and clear! Tourmaline is known for its inclusions, but this one has no noticeable inclusions even when viewed with a 10x jeweler's loupe. It's so clear, it's like one in several thousand. I couldn't hide my surprise at how high-quality this tourmaline is... (^^) When I purchased it, I was even a bit skeptical during the negotiation, wondering if it was really natural. I borrowed it from the tourmaline dealer and took it to a gemological laboratory for appraisal! The appraisal confirmed it was natural tourmaline, so I immediately called the dealer and expressed my intention to buy it!" ☆ Origin: Minas Gerais, Brazil ☆ Comes with a reliable gemological certificate. 1. 438 carats Length: 8.00 mm Width: 6.10 mm Thickness: 4.34 mm ☆ Hello, I'm a gemstone enthusiast! I studied gemstones for two years at Hiko Mizuno Jewelry College in Shibuya. My wife is also a graduate of the same school, and we are currently enjoying raising our three daughters and one son. My main business is in Thailand, the world's largest gemstone trading hub. I've been running a factory there for 30 years, catering to businesses in Japan and around the world. During that time, I've also opened shops and personally collected gemstones (loose stones) that I've come to love. Here, I'm offering the gemstones I personally collect and enjoy as a hobby at Thai local prices. I hope to make high-end gemstones more accessible to everyone and allow more people to enjoy the allure of the gemstone's home. The quality of the gemstones I offer is something I myself would want to keep for a lifetime – clear, transparent, and special loose stones.
