Kay- Authentic natural diamond pendant necklace set in 14K white gold with chain

Beautiful natural solitaire diamond pendant necklace set in 14K white gold on matching 14k white gold chain. This was a gift so I don’t know much about the quality of the diamond. I think it’s around a 1/3 of a carat in size round cut when I compare it to some of my other diamond jewelry but il not sure. Chain has clasp closure. Some very minor signs on wear on the metal but overall in beautiful used condition and would make a great gift. No original box or paperwork but will send in a small gift box.
