The listing, Size 9 blue princess cut stone ring from JewelScent has ended.
Blue princes cut ring 8mm stone (about 3 carats) not sure if it blue topaz. The ring is stamped inside but I can't read the mark.
It's a beautiful blue square cut stone, Size 9, with clear stones down the side.
I have the tag showing the value of the candle on JewelScent. It is valued at $40.00

That is the link you can verify what the ring is worth. I don't wear a size 9.
