Aquamarine Jewelry

The blue-to-blue-green variety of the mineral beryl — the same family as emerald and morganite — colored by trace iron in its crystal. It grows unusually clean, takes an excellent polish, and measures 7.5–8 on the Mohs scale, which makes it dependable for daily wear. The deeper history of the stone family is in our history of gemstones guide.

Start with the listing: we name the tier — natural, lab-grown, or simulated — in every product’s opening lines. Visually, genuine aquamarine (natural or lab-grown beryl) shows a glassy luster and a cool pastel blue that shifts slightly toward green at angles; simulated stones tend toward a more electric, uniform blue. If you want certainty on a specific piece, ask us before or after purchase and we will confirm exactly what is set in it.

It spans more price ground than almost any colored stone. That spread is the reason we run a three-tier system — the same design can meet three different budgets without hiding what it is.

It is the trade’s benchmark name for the deepest, most saturated aquamarine blue, after the Santa Maria de Itabira workings in Minas Gerais, Brazil. The historic mine is largely exhausted, so today the name usually describes color grade rather than provenance — stones from Mozambique or Nigeria can earn the description on saturation alone. When we sell a stone with documented origin, the listing states it; otherwise we price on color.

Most of it, yes — and we disclose it plainly. Rough aquamarine often carries a green cast from iron; gentle heating steadies the color toward pure blue. The treatment is permanent, stable in daily wear, and has been the industry standard for generations. Untreated stones of naturally fine color exist and command premiums, but treatment is the norm across the market, not a defect.

A legal standard, not a vague finish: the FTC reserves “vermeil” for a layer of 10K-or-finer gold at least 2.5 microns thick over sterling silver. That is many times thicker than ordinary gold-toned fashion jewelry, over a solid 925 silver base — which is why vermeil is the honest middle tier between sterling and solid 14K gold in our lineup, and why we name the standard rather than just the look.

They are fineness marks. 925 means sterling silver — 92.5% pure silver alloyed for strength, solid metal all the way through — and our sterling pieces carry a rhodium finish for a bright, white surface. 585 marks 14K gold: 58.5% pure gold, the standard for durable fine jewelry. Both stamps are your assurance the metal is what the listing says it is.

Warm water, mild dish soap, and a soft brush cover almost everything; dry with a soft cloth. Store pieces separately from harder stones like sapphire so nothing scratches, and take rings off for heavy impact work. Chains and settings in sterling benefit from the routine in our sterling silver cleaning guide — five minutes a month keeps the blue reading glassy.

Different minerals sharing a color neighborhood. Aquamarine is iron-colored beryl — pastel, glassy, subtly green-shifted at angles; blue topaz reaches a more electric, uniform blue, usually via irradiation, at a much lower price. Topaz is one of the honest materials behind our simulated tier, always named as such. Our blue gemstones guide lines up every blue stone we carry.

Yes — at Mohs 7.5–8 it wears well with basic care, and the stone’s betrothal history runs back to Roman tradition, where it stood for lasting love between partners. The practical questions — settings that protect the stone, tier choices, band pairings — have a dedicated page: see the engagement lane linked in the section above rather than buying blind from a general search.

Yes, by design rather than by box: stud earrings and a matching pendant in the same cut and metal make the classic matched set, and several of our designs exist across both categories precisely so they can be paired. Buy the pieces together or complete the set later — the tier and metal standards are consistent, so a later addition will match the first piece honestly.

The catalog grew outward from aquamarine into a full gemstone house: moonstone for adularescent white-blue, morganite — aquamarine’s pink beryl sibling — for blush bridal work, and emerald for the family’s deep green, alongside sapphire, moss agate, and more. If a design you love exists in another stone, ask — most settings can be commissioned across stones.
