turn of a finger 50,5

The punch "Dog's Head" is present and well stamped on the ring -
READ VERY VERY CAREFULLY BEFORE MAKING ANY SUFFICIENT COMMENTS - NOT APPROPRIATE AND UNUSABLE: The "Dog Head" punch is simple, is that of the small guarantee. (...) This punch that has been around since 1994 guarantees the platinum to 850 ‰ minimum. Because it is also found on works whose title is superior. It must also be known that until 1994, there was a "dog's head" hallmark that had been in effect since 1919 and who guaranteed the title to 950 ‰ only
She is in a very good condition and the diamonds are all very bright.
The ring is sold with the invoice of this one ( Expertized by a professional: auctioneer )
