An absolutely fine men's ring. Finest of the fine! Best of the best! Can I say more? This ring has a 1.57 carat Shelby Simulated Emerald. 14 kt yellow gold. In comparison to a mined gem, our 'Emerald' is the best of all the gems we make. (We make more varieties of gems in our Shelby MI factory than any other company on Earth.) Genuine emeralds are quite soft and are easily broken. Our Shelby Simulated Emerald is much harder and a whole lot 'tougher' and resistant to cracking. We are the only company in the world that makes this gem.
