① This is something I purchased here. 4 x 4 x 5 cm Approximately 55.0 grams It has a rainbow inside. The hematite also has a unique appearance with circles overlapping circles. There is a small amount of rutile in the small points on the side. I dropped it once, so there are some chips. ② and ③ are items I bought at an Asian雑貨 store. ④ is something I made myself at a Fulleren workshop. It was made of real crystal. Even if I took it apart and made something else, I think it would be a great deal. I don't know much about crystals. I bought it on impulse because it was beautiful. The purchase price of ① was about 2300 yen. I think ② and ③ were a good deal. I was taught how to make ④ by a Fulleren certified instructor. I think it cost 10,000 yen including the material fees. Instant purchase OK No price reduction is currently possible.
