Signet ring for men 14k yellow gold

A signet ring for a man, this is a very special ring made of 14k yellow gold, set with an onyx stone with gold stripes and engravings of letters on the sides.
 
What is special about this piece is that the stone is very unique, it is a black natural onyx stone with gold stripes, the stone is authentic vintage from the 60's and I only have 3 more such stones in stock, this is only 3 more units.
 
This model is best complimented by yellow gold because of the gold stripes in the stone, it is very contemporary and elegant, yet with a touch of the past.
