14k diamond ring.

14k diamond ring. Got this as a pre-engagement about 30 years ago, no sentimental value to me and I'm not sure how much it's worth or size of diamond. Just thought it's time for someone else to love. 14KP: plumb In the context of gold jewelry, "plumb" is an old-fashioned term that means that the fineness or purity level of the gold content is precisely what is stamped on the item. The word "Plumb" or the letter P still sometimes follows the metal stamp (e.g., "14k Plumb," "14KP").
