A solitaire is a single center diamond on a band, with no side or accent stones. It's the most classic engagement ring style, putting all the focus on the diamond itself. The simplicity also means the center stone's cut and quality really stand out. ### Why choose a solitaire setting? A solitaire is timeless, easy to pair with almost any wedding band, and lets the center diamond be the focal point. Because nothing competes with the stone, the quality of the diamond matters most, which is why every Ada stone is inspected in person before it enters our inventory. ### What diamond shapes work best in a solitaire? Every shape works in a solitaire, which is part of the appeal. Round brilliants give maximum sparkle, while elongated shapes like oval, pear, and emerald look larger for their carat weight and flatter the finger. The setting can be tailored to hold any shape securely. ### What if I don't know my ring size? No problem! Book a consultation, and your Diamond Concierge will be happy to assist you with finding your ring size at home. ### How long will my order take to ship? Most engagement rings on our website ship in 2-3 weeks, as every Ada Diamonds engagement ring is made to order in our New York Flagship. We do not use pre-made settings or components when crafting your engagement ring. --- Canonical URL:
