Thirty-three years after he sat down at a jewelry bench with a dream and a vision, Henry Grossbard created the first Original Radiant Cut diamond. Grossbard realized his dream of combining an emerald-cut diamond’s elegant shape with a round stone’s fiery brilliance. Original Radiant Cut diamonds make squares hip again and allow those who love to be different to wear square or rectangular diamonds without compromising magnificence.

Diamonds FAQ

Diamonds are forever, and we’re here to answer your questions so you can make an educated decision. Below are frequently asked questions our St. Louis diamond ring store receives:

Should I insure my diamond?

Insuring your diamond protects you financially should it fall out, get lost or stolen, or be significantly damaged. If any of those scenarios occurred without proper insurance coverage, you would have to replace it out of pocket. Although insuring your diamond is optional, we highly recommend doing so.

What are lab diamonds?

Lab diamonds, also known as laboratory-grown or synthetic, are dazzling gems cultivated through advanced technological processes that mimic the natural conditions under which diamonds are formed within the Earth’s mantle. These innovative methods involve exposing carbon atoms to high pressures and temperatures, allowing them to crystallize and create genuine diamond structures over a period of weeks to months. The resulting lab diamonds possess the same optical, chemical, and physical properties as their naturally occurring counterparts, making them visually indistinguishable from the naked eye. As ethically and environmentally conscious alternatives to mined diamonds, lab diamonds offer a sustainable and traceable option for those seeking exquisite and responsibly sourced gemstones.

How important is the diamond’s setting?

The term “setting” relates to how the diamond affixes to the rest of the ring. Matching your diamond size and cut with the appropriate setting is vital to giving your ring the ultimate “wow” factor. However, it also comes down to personal preference – for instance, you may want a simpler look or something more elaborate.

Which is more important: Diamond size or quality?

They are equally important since size and quality are essential factors when determining a diamond’s value. For example, a small, high-quality diamond can cost the same as a large, low-quality diamond.

What’s the difference between “carat” and “karat”?

“Carat” refers to a diamond’s weight, while “karat” describes the ratio. “Carat” is a unit of weight, and “karat” indicates the proportion of gold in an alloy out of 24 parts. For instance, 15-karat gold is 15/24 parts gold.

How is a diamond priced?

A diamond’s price depends on its four C’s – carat, color, clarity, and cut. Appraisers utilize these four notable characteristics to estimate the value of a diamond. When assessing a diamond ring’s value, appraisers consider the four C’s and band quality.
