Diamond Size

Diamond Carat

Carat is often the first thing to come to mind when thinking about a diamond’s size. Size and carat weight are closely related but there are other factors in a diamond’s appearance. Cut and shape also play a role in whether the diamond appears visually larger or smaller than its actual carat weight.

Kwiat Standards

A properly cut diamond will not have too much weight in hidden areas. The added weight increases the cost without giving the diamond a larger appearance. At Kwiat, we cut our diamonds to keep the carat weight in the right places. Each gem has the widest possible diameter to appear larger than other diamonds of comparable carat weight. And because of their superior cut, our diamonds will appear whiter than their GIA color grade. We call this the Kwiat Tiara® Cut.

Diamond Color and Clarity

Diamond Color

Diamonds are rated on a color scale developed by the GIA, the world’s premier diamond grading nonprofit. The color grading system is based on the alphabet, beginning with the letter D and running all the way through Z. A grade of D is the best possible grade a diamond can receive, which translates to an absence of color. Diamonds with this grade tend to be the most rare and valuable.

Diamond Clarity

Clarity refers to the presence of imperfections, known as inclusions, in the crystal structure of the diamond. Nearly all diamonds contain some sort of inclusion, as they are part of a diamond’s characteristics and structure. An inclusion within a diamond is natural, and on the higher end of the clarity scale, does not take away from its beauty.

My name is Greg Kwiat, and I want to help you learn everything you need to know to buy a diamond.

I’d like to introduce you to the Kwiat Round, the most exceptional round diamond in the world.

Let’s explore what makes the Kwiat Round extraordinary and how we have perfected the art of cutting this classic shape.

Round diamonds are circular in outline and are the most classic and popular of all the diamond shapes. They’re faceted with the brilliant cut pattern, which gives it all of the brilliance, fire, and sparkle that we expect to see in a diamond.

Consistent round diamond shapes first became possible with technology developed in the late 1800s. And as the art and science of diamond cutting evolved over the 20th century, the modern round brilliant became the global standard for diamond brilliance. For generations, they have held their place as the most popular diamond shape for jewelry lovers around the world.

With over 100 years of diamond cutting skill and experience, we have created the Kwiat Round. Perfectly cut, extraordinarily bright, and larger looking for its carat weight. At Kwiat, we have the strictest standards in the world for diamond cut, even stricter than the GIA.

The Kwiat Round is perfectly cut and faceted with excellent polish and excellent symmetry. With our proprietary standards and proportions, Kwiat rounds are simply brilliant, with the optimal balance of fire, brightness, and scintillation. And because of the exceptional cut quality, our rounds will appear bigger in size for a same carat weight. They will appear whiter than their GIA color grade.

To truly understand why the Kwiat round is so exceptional, it helps to compare it to lesser quality rounds that other jewelers cut and sell. All Kwiat round diamonds are excellent cut with excellent polish and excellent symmetry, referred to in the diamond market as triple excellent. Any diamond that falls short of this minimum standard is immediately inferior.

At Kwiat, our standards are even stricter than the GIA’s triple excellent grade. Only a subset of the GIA’s Excellent grading range meets our standards to achieve the Tiara logo. When diamonds fall outside Kwiat’s range, the diamond is either too deep or too shallow or loses brilliance. Diamons that are too deep will look dark, dull, and small for their weight. Diamonds that are too shallow will lose brilliance and have an unattractive, fish eye effect. By comparison, Kwiat round diamonds are always cut to the most exacting proportions and dimensions, and the result is an exceptional diamond that looks bigger and brighter.

At Kwiat, all of our diamonds are cut to our rigorous, technical, and quality standards. With more than 100 years of diamond cutting experience, we make certain that every diamond in every shape is cut to be the most beautiful that it can be. The Kwiat Round is the most beautiful and perfectly cut round diamond in the world.

THE MARK OF PERFECTION

We laser-inscribe the diamond’s girdle with our Tiara logo, a hallmark of four generations of expertise, craftsmanship, and trust. And today, it means even more: an assurance that our diamonds are natural, conflict-free, and ethically sourced from known origins.

GIVING BACK

When you choose a Kwiat engagement ring, you are also supporting our contributions to charity: water, an organization that provides clean water to people around the world. Every diamond ring sold provides water for an entire family.

BUILDING A
BRILLIANT LEGACY

Kwiat is a family business with a heritage of service, quality, and integrity. Guided by these values, Kwiat has flourished, blossoming like the family name, which means “flower” in Polish.

In 1907, Sam Kwiat opened a diamond shop in New York City; he was joined by his son, David, in 1933. Today, Kwiat has grown to become a renowned brand led by David’s son, Lowell, and his grandsons, Greg, Cory, and Russell. Like their forebears, they have perfected the science and art of cutting diamonds. And they continue the tradition of trust and authority that Sam Kwiat established more than a century ago.

CUSTOMERS ARE FAMILY

As we welcome you into the Kwiat family, we’ll share our knowledge and expertise. We will gladly provide advice that suits your situation and budget, with personal recommendations for the perfect diamond jewelry for any special occasion. We take pride in our name and what it has come to stand for. And we are grateful that customers and their families return to us again and again, generation after generation.
