Size store 5 14K Gold Diamond and CZ Ring

This is a tangled web.
First the good news. It all tested out as 14K(acid and electronic machine)
There were no markings as it has been sized.
Gave this to Karin to have the stones tested.
All the small stones are diamonds (there are 16 diamonds and pretty nice stones.)
The center (about a 10pt. stone looked perfect.(Tested as a cz)
My guess is it's a replacement for a lost diamond.
So with store all that for disclosure.I am listing it as a bargain.
It's 1.39 dwt. Looks great
