The Sultan Ring is so clean and smooth and sexy, damn! I love how it just flows right up through the stone. What a beautiful way to showcase the stone's natural allure. Cast in solid sterling silver or reclaimed brass plated in 14 carat gold and features an exquisite cabochon turquoise stone in the cavity. No nickel ever. Please specify ring size and cabochon when ordering. Choices are between turquoise, black onyx and antique coral.
