Mexican Hyalite Opal Round Bead Bracelet Power Stone Natural Stone ★ Bead Size: Approximately 7.0mm - 7.3mm ★ Inner Diameter: Approximately 15cm ※ Please refer to the grid pattern photo for the size of the stones. The grid background photo is a 1cm graph paper pattern. Rare Mexican Hyalite Opal. It looks clear, but it has a different luster than the clear feeling of crystal. Although small, the through holes are also clear, and four strands of Ope-lon rubber can pass through. Due to containing trace amounts of uranium, it exhibits fluorescence under ultraviolet light. This bracelet strongly fluoresces and changes color significantly when exposed to a UV light. You can wear it as is, or it would look great as a focal point in a design bracelet or combined with a Tenju bead. It can also be used as a handmade material for pendant tops, keychains, straps, earrings, etc. There may be natural stone-related marks, original color unevenness, chips, dents, flat areas, and rough spots from polishing. The through-hole areas may not be perfectly clean. Please understand that this item has been wrapped in cushioning material and stored since purchase, so the dirt and scratches are not recent. Please note that the color may appear different depending on your monitor. ※ Please check the condition in the photos, as the item in the photos will be sent. #HyaliteOpal #Opal #FireOpal #WaterOpal #Colored #LooseStone #BlackOpal #BoulderOpal #MatrixOpal #EthiopianOpal #WhiteOpal #PreciousOpal
