What to Know

At 1.5 carats, cut quality remains the most important factor. A well-cut stone will look noticeably larger and brighter than a poorly cut one of the same weight.

This is why every diamond in Ada's inventory is inspected in person, not just evaluated by a grading report. Two 1.5 carat diamonds with identical specs can look entirely different in real life.

Why Ada Diamonds

Ada hand-selects every diamond in person, which matters more at 1.5 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.
