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.

Ashoka Engagement Rings

ASHOKA® ENGAGEMENT RINGS

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 ASHOKA, the Diamond of Legend. Let’s learn about what makes the ASHOKA so unique and extraordinary. ASHOKA diamonds are defined by their gorgeous shape and distinctive faceting pattern. Beautifully elongated with straight edges and gracefully rounded corners, they are perfectly cut with 62 facets that create a dazzling prismatic effect. ASHOKA diamonds have exceptional polish and symmetry, and they appeal to those who want something truly different and rare. Fewer than 1% of the world’s rough diamonds meet the exacting criteria to become an ASHOKA diamond. The ASHOKA shape combines the elegant elongation of the emerald cut with the soft corners of the cushion shape. The proprietary faceting pattern gives it a unique and elegant sparkle unlike any other diamond in the world. Because of their cut, Ashoka diamonds will appear 30 to 50% larger than other diamond shapes of the same carat weight, also appear wider than their GIA color grade, and when worn in a ring, the ASHOKA shape can seem to elongate the finger. The legendary Ashoka diamond is rare and highly desired, only available with Kwiat in the United States.

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.

RESPONSIBLE AND TRANSPARENT

Every Kwiat Tiara diamond is cut from the rough stone by Kwiat and can be traced to its country of origin. This guarantees that the diamond is conflict free and sustainably and ethically mined.

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.

THE WORLD’S MOST PERSONAL DIAMOND

We’ll help you select a natural, conflict-free, and ethically mined rough diamond and invite you to follow along as its cut and set in a handcrafted ring designed to your specifications. Or, you may choose a diamond that’s already been cut or a completed ring.

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.
