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.

Kwiat X Charity: Water


Clean water means economic and social development, healthier populations, and brighter futures for families in rural communities. Charity: water funds water projects in areas of greatest need and works with local partners to implement and sustain them.


Every cuff sold will provide clean water for one person in Tanzania. Your purchase can change lives.

Currently, 771 million people across the globe live without access to clean water. Charity: water is a non-profit whose mission is to change that by bringing clean and safe drinking water to people in developing countries. To date, charity: water has funded 120,784 water projects around the world to help over 16.8 million people get access to clean water, hygiene, and improved sanitation.


“Charity: water is an organization we’ve respected and admired for a long time,” says Kwiat CEO Greg Kwiat. “We’ve collaborated in the past as our core values align so well, and we couldn’t be more excited to partner with them again.”

The newly released Kwiat x charity: water cuff celebrates our fundamental life source. Its fluid, organic shape is inspired by a water droplet and highlighted by a round brilliant diamond. 100% of profits from the sale of this cuff will help change the lives of women and girls in Tanzania, who often bear the burden of water collection and are disproportionately affected by the global water crisis.


“It is a privilege to collaborate with a distinguished family-owned company renowned for their craftsmanship and superior quality,” adds Scott Harrison, founder and CEO of charity: water. “I am honored to introduce this exclusive limited-edition cuff to the public, and I look forward to witnessing the impact charity: water and Kwiat will make together. Through our joint efforts, we will spark meaningful change and make a transformative impact in some of the world’s most vulnerable communities.”

Every cuff sold will provide clean water for one person in the Dodoma and Kigoma Regions in Tanzania. Our goal is for the sale of these cuffs to bring clean and safe drinking water to an estimated 429 people in Tanzania for the very first time. “As a diamond producing region, it’s very near to our hearts,” Greg explains. “We feel it’s important to give back to the local community and make sure they have access to the most important resource of all: clean water.”
