Beautiful vintage designer ring with 5 luminous green tourmaline .The ring weighs 2.6 grams and it is crafted of 10 k yellow gold.The main stone measures 8/6 mm , the others are slightly smaller and have a beautiful light green color.The ring is hallmarked inside the shank. Sanuk was a jewelry manufacturer located in San Diego, California but the seem to have gone out of business in 2001.The ring had white topaz stones, one was missing so I changed all of them.Feel free to contact me if you have questions.2
