This is a stunning and substantial statement ring featuring a beautiful 3.70-carat smoky quartz gemstone. The stone is securely set in a prong setting that's made from a combination of sterling silver (925) and 14k yellow gold, giving it a two-tone look. The band and setting have an 'antique finish,' which means it has a slightly darkened, vintage-style patina in the crevices to highlight the details, contrasted with polished highlights. Smoky quartz is known for its translucent gray to brownish-gray color. This ring is available in women's sizes 6, 7, and 8. As with many gemstones, some smoky quartz is treated (often by irradiation) to enhance its color. Care is easy: avoid harsh chemicals and ultrasonic cleaners; just use warm soapy water and a soft cloth. It comes presented in a nice jewelry gift box, making it ready for a special occasion like a birthday, anniversary, or as a treat for yourself. A bold and elegant piece of jewelry.
