Silver crystal pendant necklace with lobster clasp. - Brand: 4C - Material: Platinum - Design: Pendant - Clasp Type: Lobster clasp Thank you for viewing. I don't remember when I purchased this. I also don't remember the purchase price. I don't recall ever wearing it, so I've listed it as "Like New." I don't know what kind of stone it is, so I apologize, but I won't be able to answer any questions about it. I would appreciate it if those who understand that this is a used item would consider purchasing it. Please refrain from purchasing if you are overly sensitive to such things.
