925 Silver Blue Cat’s Eye Stone Ring

I bought this beautiful 925 ring when I was in 2004. I resized it to fit my finger. Because the gem cannot stand heat, the jeweller left it open. The gem is a deep blue with that cat eye effect. Please check pictures for more details. The ring should not be forced a size down or up as it is not a resizable ring. It fits well a 4.5-5US.
