***We warmly welcome your purchase of loose gemstones!*** However, please feel free to contact us if you would like us to create jewelry for you. We have received many inquiries from customers 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 an item 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's featured special gemstone!"

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 have been running a factory there 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, offering them at Thai local prices. I hope to make high-end gemstones more accessible to everyone and allow you to enjoy the charm of the gemstone's home. I only offer gemstones (loose stones) that I myself would want to keep for a lifetime, so please feel free to browse with confidence. Thank you for your interest.
