What to Know

2.25 carats is a size people land on intentionally. It offers meaningful presence without the premium of a round number, and looks especially striking in elongated shapes.

No matter what size diamond you're considering, curation matters. You should never choose a diamond based on a grading report alone. While two diamonds may share identical 4Cs, they can look very different in person. Every diamond at Ada is hand-selected in person by our expert team. We curate only the rare few lab grown diamonds that meet our standards for cut precision, light performance, and beauty in real life.

Why Ada Diamonds

We know that a purchase this important deserves an exceptional experience. Whether you purchase online, or enjoy complimentary design support with a Diamond Concierge, each piece is made to order and crafted in house from start to finish. Our master jewelers create each setting one at a time, built specifically for its stone. Nothing is mass-produced. Every detail is considered, refined, and made to last for a lifetime.

Color

Color

Diamond color measures the subtle tint present in a diamond. Learn how the D–Z color scale works, what color grades look white to the eye, and how Ada Diamonds evaluates lab diamonds for brightness and undesirable color undertones.

Clarity

Clarity

Clarity is a measurement of how many or how large of blemishes or inclusions are present in the diamond. The lower the clarity of a diamond, the more imperfections in the diamond. Lab diamonds vary in clarity, just like mined diamonds.

Carat

Carat

Carat weight measures how much a diamond weighs, not how large it appears. Learn how carat weight influences a diamond’s size, rarity, and price, and how Ada Diamonds helps clients find the right balance of beauty, proportions, and value.
