***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 piece of jewelry, a full custom order, rather than using a ready-made setting. *** "We only offer gemstones of a grade that we believe will last a lifetime or be passed down through generations!" ☆ November Birthstone: Blue Topaz [Rarely seen in the market these days!

I studied all aspects of 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 distribution center. 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 would like to introduce the gemstones I personally love and collect as a hobby, at Thai local prices. I hope that more people will feel closer to the high-end world of gemstones and 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 support.
