When you think of diamonds, it is typically the classic diamond that comes to mind, and for good reason. The colorless diamond has been a staple in fine jewelry for decades because of its unrivaled style and grace.

However, diamonds come in so many different shapes and sizes that it is often overwhelming when it comes time to choose the ideal diamond for you.

At Alex and Company, we offer the finest diamond jewelry in Boston with an array of brilliant diamonds for every taste and budget with a knowledgeable staff to guide you. Whether you are familiar with diamond jewelry shopping or are new to diamonds altogether, we guarantee that your search for the perfect diamond end at Alex and Company.

We specialize in exceptionally brilliant diamonds certified by the Gemological Institute of America (GIA) which adhere to a strict quality evaluation established by the “4Cs” – diamond color, clarity, cut, and carat weight. These 4Cs of diamond quality are rules to live by for every jeweler, and the master jewelers and gemologists at Alex and Company are no different.

Oftentimes, a higher carat diamond is thought to be a higher quality diamond and, therefore, worth more. However, the true quality of a diamond is defined by a combination of the 4Cs.

Each of the fine diamonds in our jewelry collection meets the GIA guidelines and adheres to the 4Cs to offer you the most brilliant, quality diamonds for your piece of jewelry.

As a fine Massachusetts diamond jewelry dealer, we offer ideal cut GIA certified diamonds and beautifully cut fancy diamond shapes to guarantee quality and brilliance. Learn more about the 4Cs and the various diamond shapes here, or visit our store today to browse our full collection of magnificently cut diamonds.
