This is a 10 k smoky topaz that is a 1974. On one side one prong moved because my fingers were very warm from dancing in my 20s...I looked down and saw it ..I never had a jeweler fix it .otherwise it has Been sitting around for 50 years in a box . the topaz is perfect except for one prong leaning to the left. I will take a picture and add it please give it a look it is very well made...thank you for looking
