These are refreshing blue and green colored beads. I received them from my grandmother around May of last year and have been storing them in a dark place. Personally, I think they are probably natural stones, but as I am an amateur, I cannot determine the material. Therefore, I will list them as material unknown (*_*; Sorry. For your reference on the material ↓ Water sinking test → They sink to the bottom of the water with a "thud." Loupe test → Many fine white cloudiness and black inclusions can be seen. Touch test → They feel cool to the touch and the sensation lasts for a certain amount of time. Mineral app test → Amazonite, aventurine, and jiamonseki (likely a misspelling of "jasper") were indicated. ※ They have weight. They are definitely not acrylic. (Amateur judgment (⁠*⁠﹏⁠*⁠;⁠)) I hope you can use them as parts for handmade creations♪ They are multi-faceted like a soccer ball and sparkle when light hits them, and all the colors are very beautiful. Each bead has its own individuality, and I think there are no two alike (*^^*) They have a very luxurious feel♪ There are some color unevenness and white cloudiness or black parts that look like inclusions in places. Please check the actual condition in the photos. They are loosely tied with fishing line to prevent them from scattering. They can be untied easily. Please use them as individual beads. 【Size】 Bead size: A.E Approximately 12mm B.C.D.E Approximately 10mm Hole size Approximately 1mm Total 212 pieces 321g ※ Please note that there may be some errors due to amateur measurements. 【Notes】 ● No certificate of authenticity is included. ● Some beads have irregular shapes, stains, or chips.
