Purchased from KIWA Seisakusho. It's a Swarovski crystal. The second photo shows a triangular marking, like an eye. Please check the fourth photo for a slight chip. Please purchase only if you understand. There's a hole across the top, so you can thread your favorite string through it to make a suncatcher. The way it catches and reflects light is very beautiful. I was planning to make a suncatcher, but I never used it and just kept it in storage. I hope someone will use it. #handmade suncatcher #Swarovski #handmade parts #crystal #suncatcher #fengshui #goodluck
