When it comes to selecting a diamond ring, people can find some stores that offer custom made pieces. The custom diamond rings Brentwood stores offer will usually allow the shopper to select the type of diamond they want set within a particular band. A diamond can be selected according to the different features it possesses. The clarity is defined by how clear the interior spaces are. The color can also be selected according to what the customer wants to have. While white diamonds are the most popular colors used, there are also diamonds in shades of blue and yellow. Customers can also choose the shape of their gemstone.
