Vintage platinum diamond ring

This is a vintage platinum diamond ring there are 7 diamonds I’m sorry to say I don’t know the clarity or the color of the diamonds I know that it was originally $4000.00. And I think the size is a six or seven. Sometime this week I was gonna go and get it appraised so I should have more information then but I know definitely it’s vintage and the diamonds are real and it’s platinum and I know the original price was $4000.00 it’s antique and it’s a beautiful ring the diamonds are very beautiful in person. FYI also I recently found out that inside the ring is engraved 10%IRID 90%PLAT and to a wonderful surprise this means the ring is more valuable then just a platinum ring by itself!
