***We warmly welcome your purchase of loose gemstones! However, if you'd like us to create jewelry for you, please feel free to ask. We've received many inquiries from customers who purchased gemstones as loose stones but were unsure where to have them made into jewelry. Therefore, we are now offering jewelry creation services on Mercari. If you purchase an item from us, we will create a unique, comfortable-to-wear, custom-made piece of jewelry, rather than using a pre-made setting.*** "We only offer gemstones of a grade that we believe will last a lifetime or be passed down through generations!" ☆ November's Birthstone: Blue Topaz 【Rare and Authentic!

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 now enjoying raising our three daughters and one son. My main business is in Thailand, the world's largest gemstone trading country. I have been running a factory for 30 years, catering to businesses around the world, mainly in Japan. During that time, I have also opened shops and personally collected gemstones (loose stones) that I liked. Here, I am offering the gemstones I personally love and collect as a hobby at Thai local prices. I hope that this will make high-end gemstones more accessible to more people, and that you will enjoy the charm of the gemstone's home. I am confident in the quality of the gemstones, as they are all gemstones (loose stones) that I would want to keep for a lifetime. Please feel free to browse with confidence. Thank you for your interest.
