I have a cat. Please refrain from purchasing if you are concerned about cat hair or allergies. I check the condition before listing, but there may be oversights. I have not color-corrected the images, but please note that the color may vary depending on your device. For price negotiations, please make your offers within a reasonable range via comments. This was a gift, but I have no use for it, so I am listing it. I was told the stone is a natural stone, but I don't know the details. I don't think it's a diamond. I don't know the material either. There is no color fading. Please check the size in the images. There may be chips or cracks if you look closely, but I couldn't see them with the naked eye.
