This awesome Brazilian smoky quartz gemstone measures 9mm x 9mm and is bezel-set in solid sterling silver that has been plated with rhodium to give it a mirror shine, add durability and to prevent tarnish. The gemstone is a nice shade of brown and is approximately 3.10 ctw. I love the sleek design of the ring, and the highly polished silver next to the brown of the quartz is pleasing to the eye. The band is 4mm in width at the base, which will tend to make it comfortable to wear and it flares to 9.8mm at the top of the ring. There is an ample amount of silver in this ring, as it weighs 7.8 grams on the scale. It was crafted in Thailand and has been sized to a 8.75. The ring is stamped 925 and signed BBJ. The ring is very handsome and at this price, it will make some man very happy!
