AJM gold ring teal blue gemstone size 7

Great preowned condition Small flaw Very pretty gold ring. There are some stamps inside. AJM and a few others I cannot make it out. I do not know if it is Sterling or gold filled but I believe it is just a very nice costume wearing. The stone color is gorgeous like a deep teal blue. See photos for details and measurements. See my reviews for buying confidence. Smoke free home. Fast shipping!
