Vintage 14K Yellow Gold Amethyst Diamond Ring

Pretty and feminine vintage marquise amethyst with two small diamonds ring. Probably from 60’s to 80’s. The pear shaped amethyst is a strong purple and the two small diamonds sparkly. Not dull and flat. It weighs 2.42 grams and a size 6. The band could be made larger. Stamped on the interior JK on one side and 14k on the opposite side of the band. I cannot get clear pictures of either. Simple and unfussy ring, prong set stones. No problems given its age.
