Timeless Diamond Jewelry for All Occasions

Gusterman’s in Denver, Colorado, offers diamond jewelry in a range of styles, shapes, and quality levels. Diamonds are used in jewelry in a variety of ways to add distinct allure to the wearer. When choosing a diamond for a wedding set, as a gift for a loved one, or for yourself it is important to understand that the “best diamond” is the diamond that is best for you.

A stone with perfect cut, clarity, and color is expensive. A diamond of good color and cut with eye-clean inclusions will give you a fine stone representing excellent quality and for the same expenditure you will be able to purchase a larger stone. Before you purchase a stone, please read the following information and look through the stones that are available by special order. We are available to help you with your purchase and to ensure that you always get the stone that is best for you. Please call for more information.


Cut: The most popular cut is a modern American brilliant. Other common cuts include princess, radiant, emerald, oval, pear-shape, marquise, trillion and heart-shaped.

Clarity: Although a flawless stone is valuable many stones that fall within the VS2-SI1 range are eye-clean, meaning that the inclusions are not visible with the naked eye. A microscopic inclusion will always serve as an identifying characteristic of the stone. Since inclusions affect the overall look of a stone as much as color and cut, an eye-clean diamond with excellent color that well-proportioned will have a dazzling appearance.

Color: Most diamonds that appear colorless actually have slight tones of yellow, brown, or grey. As these tones become more apparent they are graded lower on the GIA scale (ranging from D to Z). D stones are considered colorless. A good stone often falls within the F to H range.

Carat: The word carat is derived from carob, a small bean remarkable for its uniformity of size, which was once used in weighing gemstones. A carat is divided into 100 points. A half carat stone would be 50 points and a one point diamond is 1/100th of a carat. Purchasing a diamond with an accompanying grading report or diamond certification is strongly encouraged. The two most common reports originate from the GIA (Gemological Institute of America) and the EGL (European Gemology Laboratory).



Stone Setting

With more than 50 years of experience, Gusterman’s has used many creative methods to set stones. We help you choose the setting style that is secure, follows the style of the band, and best showcases the stones. In addition to popular setting styles such as pave, channel, bezel, and prong settings, we create custom stone settings per your description. For example carved hands, twigs, and other unusual shapes can be used to set stones.

Broad Design

Whether we start with a diamond or setting preference, we often sketch design options with clients to provide a visualization of their engagement ring. Wedding bands can be subtle and plain to allow the diamond to get attention or be intricate and detailed showing rare design aspects.
