DOMINIQUE DINOUART MEXICO DDD 925 THIS IS A BEAUTIFUL SILVER RING MARKED INSIDE AS SHOWN IN PHOTO #4 IT HAS A RETICULATED STYLE WITH A LOVELY GREEN/BLUE STONE GENTLY USED MAKES A WONDERFUL GIFT SIZE 7 RING WEIGHS 7. 33 GRAMS I am no expert when it comes to listing jewelry. I'm uncertain of the type of stones and their quality. But I can tell you what looks nice and describe the merchandise to the best of my ability. So I can tell you now " let buyer beware" and purchase with that information in mind. If I undersell something because I'm not totally aware of it's true value, that's my bad and you end up with a great deal. Just selling these inherited rings and other jewelry to help a friend settle an estate.
