Aquamarine Jewelry

Aquamarine jewelry is any piece set with aquamarine, the blue variety of beryl. Ours sets natural aquamarine in solid 14K white, yellow or rose gold, with platinum on most designs and 18K gold on the engagement rings. The collection covers solitaire, halo and cocktail rings, engagement rings, necklaces, pendants, earrings and a bezel-set cuff.

Yes. Every aquamarine in this collection is natural, mined aquamarine, and each product page states it. Accent stones are listed separately; two rings use laboratory-grown diamond accents, and their titles say so.

Yes. Aquamarine is the March birthstone, and GIA lists it for the 19th wedding anniversary. See the March birthstone for more.

Deeper, more saturated blue is the most valuable, ranging from blue to a slightly greenish blue. Pale stones cost less and look best in larger sizes. Clarity is usually excellent, so color is where to focus.

Often, yes. Many aquamarines are heated to remove a green tint and leave a purer blue. The treatment is routine and stable in normal wear. If you would like to know more about a specific stone, ask our concierge.

Yes. Aquamarine rates 7.5 to 8 on the Mohs scale, durable enough for everyday wear, including rings. Like any gem, it can chip with a hard knock, so a halo or bezel adds protection, and it is wise to remove rings for the gym or heavy work.

They are among the better colored-stone choices. Our aquamarine engagement rings come in halo, three-stone and solitaire designs with round, oval and cushion centers from 1 to 2 carats, in 14K or 18K white, yellow or rose gold. Expect to have the prongs checked occasionally, as with any ring worn daily.

Its name means seawater, and sailors once believed it calmed the waves and kept them safe. It was also thought to bring happiness in marriage, which is part of why it is a favorite anniversary and birthday gift.

Use warm water, mild dish soap and a soft toothbrush, paying attention to the back of the stone. Ultrasonic and steam cleaners are usually safe if the stone has no fractures or liquid inclusions. More in our jewelry cleaning guide.

White gold and platinum keep aquamarine cool and icy, the most popular look. Yellow gold warms it and adds a vintage softness; rose gold gives a gentle contrast. Most pieces come in all three colors of 14K gold, and many also in platinum.

Both are blue and can look alike. Aquamarine is beryl, usually a softer, slightly greenish blue, and its color is natural or gently heated. Most blue topaz starts colorless and is treated to a stronger blue; it is harder at 8 but less tough. Compare in topaz jewelry.

Yes, one: a bezel-set aquamarine cuff in 14K white, yellow or rose gold, shown in this collection. There are no boxed sets, but many earrings and necklaces share stone shapes and settings, so a matching pair and pendant is easy to put together.

Brazil is the classic source, especially the state of Minas Gerais, with fine stones also mined in Nigeria, Mozambique, Madagascar and Pakistan. Each product page states whether a stone is natural or lab-grown and lists any treatment.

Every aquamarine ring is made to order in the size you select, and rings are final sale, so measure first with our sizing guide. Between sizes, choose the larger one for wider bands.
