Oval-cut iolite ring made of sterling silver 925, with round-cut side stones. - Material: Sterling silver 925 (stamped in image 3) - Main stone: Iolite - Main stone color: Purple - Main stone shape: Oval cut - Side stones: Unknown details, likely glass. - Number of side stones: 2 - Side stone shape: Round cut - Ring size: Approximately size 7 (Japanese size) - Note: Regarding the size, I have measured it using a measuring tool and compared it with other personal rings, but please understand that this is a measurement by an amateur. Thank you for viewing. I purchased this a long time ago, but I'm letting it go because the size no longer fits. Since it has been a long time since the purchase, there are signs of aging in the details, but I don't think there are any major problems with the condition of the main stone. I hope that those who can understand the above, based on the images, will welcome it. I hope it reaches someone who will cherish it more than I did.
