Diamond Cuts

U.S. Coins & Jewelry is committed to making the process of buying and selling diamonds as easy and stress-free as possible.

As Houston’s #1 diamond & jewelry buyer, our family-owned and operated retail center offers you a safe, secure option to sell your diamond and get the best possible price in the city of Houston. Our diamonds experts appraise your diamond and make you a fair offer based on the quality size, shape, and color of your stone. Let’s face it, every diamond is valuable, and they come in a variety of sizes, shapes, and colors, with various internal characteristics. The value of each diamond is based on a combination of factors. Rarity is one of those factors. Diamonds with certain qualities are rarer, therefore more valuable.

A diamond has to go through a lot before it reaches the jeweler’s display case. It forms deep in the earth under extreme heat and pressure. It’s ejected violently upward until it arrives at or near the earth’s surface. It’s forced from its hiding place by nature or by man. Then it’s cleaned, cut, and polished until its natural beauty shines through.

At U.S. Coins and Jewelry, we offer highly competitive prices for both your loose or mounted diamonds. If you want to sell your diamond or trade it in for a larger one, U.S. Coins and Jewelry is the right place. We will meet or beat any fair competitor's price. Our GIA certified experts will be happy to give you a quote on the spot or show you our vast selection in stock. At U.S. Coins and Jewelry, we want you to be happy, and a good deal to us is when both parties are completely satisfied.

The Secret Behind the 4Cs What Every Buyer or Seller Should Know

GIA created the first, and now globally accepted standard for describing diamonds: Color, Clarity, Cut, and Carat Weight. Today, the 4Cs of Diamond Quality has become the universal method for assessing the quality of any diamond, anywhere in the world.

Visit our showroom and allow us to help you understand the basics of diamond grading. By understanding the basics, you can make an informed decision when buying or selling your diamond. At U.S. Coins and Jewelry, we take the time to educate our customers so that they can get the best deal in Houston.
