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.

“I can’t stop smiling at the sparkle”

Lisa purchased East-West Kwiat Cushion™ Diamond Engagement Ring with Pavé

Megan the concierge and her team were so helpful throughout our engagement ring selection process. They explained what made each cut so special and eventually we landed on a Kwiat cushion cut. Not only is it a little bit different from the usual shapes I see, but I can’t stop smiling at the sparkle. It’s just perfect and I couldn’t be happier.…more


“production team did a wonderful job”

Helen purchased {product name}

When searching for engagement rings, we narrowed it down to a handful of stores. Having spoken to someone at each, we felt that Megan and her team at Kwiat really understood what we were looking for. I guess when you’ve been in business for 115 years, you have a good customer sense. Even at our first appointment, we felt like Megan derived as much pleasure helping us as we did picking out the perfect ring. She made us feel like she had all the time in the world for us and once we’d made our selection, she was in touch with us to confirm timing and kept us up to date on progress. Better still it was being made in the store. So excited for my next trip there to take advantage of Kwiat’s bridal borrow program while selecting a wedding band too.…more
