This is an opal from the Hosaka region. Today, we found a play-of-color opal of the highest quality ever! Since the Hosaka opals I listed were not purchased, I broke open 3 accompanying nodules as promised today☆ One of the results is this super play-of-color opal shaped like Mt. Fuji☆ It's such a beautiful Hosaka opal that I almost don't want it to sell (lol). It is said that it cannot be collected now because the mine has closed. It is said to have been miraculously born from the seabed millions of years ago. I took this photo with my phone under a light bulb. This is a precious item that I received previously. I was surprised to see how expensive it was on mineral sales sites. Since this is a personal listing, please take it at a low price. Please check the ruler for the size of the mineral.
