(SOLD) 10KP ruby and diamond ring

this is a very nice looking Ruby or Garnet and diamond ring size is about a 6 to a 6 1/2 --> (2.67)grams. this ring says 10KP with initials GTR inside The KP stands for "Karat Plumb". ... Furthermore, even though the USA only allows jewellery to be sold as gold with a minimum of 10 carats purity, the 0.5 carat leeway still applies and 9.5 carat is the actual minimum. So, as a consumer you'd be better off purchasing a ring stamped 10KP than a ring stamped 10K.
