Aquamarine Necklaces

Aquamarine is the blue to blue-green member of the beryl family, the same mineral group as emerald. Its name points to seawater, and the color here ranges from a pale sky blue to a medium blue-green. The stones set in these necklaces are genuine natural aquamarine. Like most aquamarine sold today, they are heat-treated to even out the color and bring the blue forward. That process is permanent and stable, it is standard practice across the fine-jewelry trade, and it does not make the stone any less real. Each product page lists the exact stone size for that design, so you know what you are getting before you order. If you have a question about a particular stone or want something outside the listed options, our concierge can help you choose or customize a piece to your preference.

Yes. Aquamarine sits between 7.5 and 8 on the Mohs hardness scale, which is hard enough for regular necklace wear. A necklace also has an easier life than a ring, since it does not take the daily knocks your hands do. That said, treat it with sense. Take it off before the gym, gardening, or anything that might bang the stone against a hard surface, and store it separately so harder gems do not scratch it. Put your necklace on after makeup, perfume, and hairspray, and take it off before you sleep to spare the chain. The settings are solid 14K gold or platinum, never plated, so the metal holds up over years of wear. With basic care, an aquamarine necklace is well suited to everyday use, and a quick clean now and then keeps the blue looking bright.

Both. Aquamarine is the birthstone for March, so a necklace makes a natural birthday gift for anyone born that month. It is also the traditional gem for a 19th wedding anniversary, which makes it a thoughtful marker for that milestone. The soft blue color reads as calm and easy to wear, and it flatters a wide range of skin tones and wardrobes. Because the collection runs from plain solitaires to diamond-accented designs, you can match the piece to the person, a quiet everyday pendant for one recipient, a halo style with more sparkle for another. If you are shopping across birth months for family or friends, the wider birthstone necklaces edit is worth a look. Every necklace ships with free insured shipping and easy returns if the recipient would prefer a different style.

The collection has 24 active styles, so there is real range. Stone shapes include pear, round, oval, emerald-cut, square, marquise, and hexagon. On the design side, you will find diamond halos, a starburst halo, round and square solitaires, an emerald-cut diamond halo, and an oval deco halo for people who want sparkle around the blue. There are also cross styles, including an upright aquamarine cross, a sideways cross, and a marquise cross. For a cleaner, modern look, browse the bar designs, a diamond bar, a three-stone bar, a bezel-set bar, and an accent bar, plus drops like a pear diamond drop and a bezel drop bar. Disc and open shapes round things out, with a polished disc, a diamond disc, an open circle, and an open square. Each product page shows the exact metal, stone size, and any diamond detail for that piece.

It comes down to the look you want and how the color plays against your skin. White gold and platinum are both cool and bright, and they let the blue of the aquamarine stay center stage, which is why a lot of people pick them for this stone. Yellow gold gives you warm contrast, so the blue looks cooler and a little more vivid next to it. Rose gold is softer and pinker, a gentle pairing with pale blue. Platinum is the densest and most durable of the four and holds a bright white without any color change over time, though it costs more than gold. All of the metals here are solid 14K gold or platinum, never plated, so none of them will wear through to a base metal. If you are torn, our concierge can talk you through it.

Aquamarine necklaces in this collection come on a 16 inch or an 18 inch chain. A 16 inch chain sits high, close to the base of the neck, and works well above a higher neckline or as the top layer in a stack. An 18 inch chain drops a little lower, usually landing right around the collarbone, which is the most popular everyday length and easy to pair with most tops. If you like to layer, mixing a 16 inch and an 18 inch gives you a clean gap between pieces. The right length also depends on your neck and frame, so if you are between sizes, the shorter chain reads more delicate and the longer one a touch more relaxed. Should you need a length that is not listed, our concierge can arrange a custom chain to fit.

Many of them do. A good number of the aquamarine designs pair the blue center stone with small natural diamonds, used as a halo around the stone, as a starburst, in a bezel, or set along a bar. These are genuine natural diamonds, not simulants, and each product page states exactly where and how they appear on that piece. Other styles are plain aquamarine with no diamonds at all, which keeps the focus on the color and usually comes in at a lower price. So you have a choice, more sparkle and detail with the diamond-accented designs, or a cleaner, quieter look with a solitaire or a plain disc. If you want the specifics for a style you are considering, check the product page or ask our concierge, who can confirm the diamond details and help you compare options side by side.

It makes a strong gift for a few reasons. Aquamarine is the March birthstone, so it is an easy, meaningful pick for a March birthday, and it is the traditional 19th-anniversary gem for couples marking that year. The soft blue is easy to wear and does not compete with someone's existing jewelry, which helps if you are not sure of their taste. You can also match the style to the person, a simple solitaire for someone who keeps things low-key, or a diamond halo for someone who likes a bit of shine. Since the price on the page is the finished necklace with its chain and stones, there are no surprise add-ons at checkout. Free insured shipping, easy returns, and a lifetime warranty take some of the risk out of buying jewelry as a gift, and each piece arrives ready to give.

Prices in this collection start around $609 and run up to about $3,229, depending on the stone size, the metal, and whether the design includes diamond accents. The number you see on each product page is the price of the finished necklace, with its stones and chain included, and nothing is added at checkout. Plain aquamarine solitaires sit toward the lower end, while larger stones, platinum settings, and diamond-heavy designs cost more. Every piece is made and set to order in solid 14K gold or platinum, never plated. Your order also comes with free insured shipping, easy returns, and a lifetime warranty on the piece. If you have a budget in mind and want help finding the best style within it, our concierge can point you to the designs that fit, or customize a piece so it works for you.

Cleaning is simple. Use warm water with a drop of mild dish soap and a soft brush, gently work around the stone and setting, then rinse and dry with a soft cloth. That handles the everyday film from skin, lotion, and dust. Keep the necklace away from hard knocks and from prolonged strong heat or direct sunlight, since long, intense exposure is not ideal for the color. Ultrasonic cleaning is generally fine for a clean aquamarine, but skip it if the stone is heavily included, as the vibration can stress internal flaws. Store the piece on its own, in a pouch or a lined box, so harder gems do not scratch it and the chain does not tangle. Put it on last when you dress, after perfume and hairspray, and take it off before you sleep or shower. With this routine, the blue stays bright for years.
