We warmly welcome purchases 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 through a full custom order, rather than using a pre-made setting. "We only offer gemstones of a grade that we believe will retain their value for a lifetime or be passed down through generations!" ☆ September Birthstone, One of the Five Great Gems Natural Royal Blue Sapphire "The most beautiful, vibrant Royal Blue Sapphire! This is a top-quality Royal Blue Sapphire that we, the gem dealers, are serious about! Of course, it's from the famous Sri Lankan mines. These are rarely seen in the market these days, and even when they are, they often have a dull or milky color. You rarely find high-quality ones. I was truly lucky to find this one, so I got it immediately! The color is beautiful, and the transparency and brilliance are perfect! I've worked in the gem industry for a long time, and this is a genuine piece that I rarely see." ☆ Comes with a reliable gem identification report, so you don't have to worry after your purchase, wondering if it's genuine. 1.087 carats Length 5.95 mm Width 5.25 mm Thickness 9.67 mm ☆ Hello, I'm a gem enthusiast! I studied gems 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 gem trading country. I've been running a factory for wholesalers from Japan and around the world for 30 years. During that time, I've also opened shops and personally collected gemstones (loose stones) that I liked. Here, I'm offering the gemstones I personally enjoy and collect, at Thai local prices. I hope to make high-end gems more accessible to everyone and allow more people to enjoy the appeal of the authentic gem world. Regarding the quality of the gems, I only offer gemstones (loose stones) that I would want to keep for a lifetime.
