Round Blue Sapphire

Round blue sapphire engagement rings are among the most beautiful engagement rings in history. They also have a royal pedigree! In fact, Princess Diana’s stunning blue sapphire halo ring is one of the most well known and loved engagement rings of all time. So, choosing a blue sapphire engagement ring means you’re picking a classic. It also means you’re getting a great value! That’s because our top grade AAA round blue sapphires are over than 50% less expensive than a round diamond of the same size!

All of our natural blue sapphires are cut to maximize sparkle and bring out this dazzling blue color! They are also eye clean (so, they have no visible imperfections) for max beauty. Once you select your size (choose from a classy .50ct (5mm) up to a whopping 2.20ct (8.5mm)!), our gemologist will hand pick the best stone from at least 5 AAA round blue sapphires. We’re picky, so the blue sapphires we sell are among the most stunning in the world. And, we will email you a photo of your hand selected top AAA blue sapphire approximately 24 hours after your purchase upon request! Have questions? Send our gemologist a note here, or email us at [email protected]!

Did You Know: Because sapphire is denser than diamond, your sapphire will have a larger carat weight than a diamond with the same measurements. So, to make your choice easier, we have listed millimeter sizes below. Also, we have listed what an equivalent sized diamond would weigh! For example, a 5.0 mm round blue sapphire would weigh .65 carat (whereas a 5.0mm diamond would weight only .50 carat).
