What to Know

The 2-3 carat diamond is our most popular size range at Ada. A round brilliant at 2 carats typically measures about 8.1 to 8.2mm face-up, which on most finger sizes, is eye-catching and dramatic without feeling too large.

Like all diamond sizes, there can be significant variations in quality and how a diamond looks in real life within the same size range and same 4C grades. Two 2 carat diamonds with identical specs can look entirely different in real life.

This is why every diamond in Ada's inventory is inspected in person, not just evaluated by a grading report. We pre-select the most exceptional lab diamonds at every size range, so you can choose with confidence.

Why Ada Diamonds

Ada hand-selects every diamond in person, which matters more at 2 carats than many buyers expect. At this size, small differences in cut quality, light performance, and color consistency show up clearly in real life.

Our team reviews each stone up close, in multiple light environments, before it ever becomes part of our inventory. A grading report is a starting point, not the whole story.

From your first conversation to the moment your ring arrives, you'll work directly with a Diamond Concierge who knows your preferences and stays with you through every decision. Every ring is made to order in our NYC flagship, built around the exact stone you choose.
