This collection gathers every blue stone we set in one place — sapphire, aquamarine, London blue topaz, tanzanite, turquoise, lapis lazuli, and the starlit shimmer of blue sandstone — across 925 sterling silver, 14K gold vermeil, and solid 14K gold. Rings, wedding bands, couples sets, and necklaces, handcrafted and hand-finished since 2016.
The Many Blues of the Gem World
Blue gemstones run from the palest sky to the depths of the midnight ocean, and the difference is written into the stone itself — iron and titanium lend sapphire its royal saturation, iron gives aquamarine its sea-clear cool. Blue is consistently the most requested color in fine jewelry, and the reason is less fashion than feeling: it reads as calm, as constancy, as something that holds. That emotional steadiness is why it has anchored engagement rings and heirloom pieces for centuries.
The Most Popular Blue Gemstones
When people picture a blue gemstone, they are usually picturing a sapphire. Corundum in its blue form sits at a formidable Mohs 9, second only to diamond, which is precisely why it has become the quiet standard for a ring meant to be worn every day for a lifetime. Its color spans cornflower to deep royal, and that range is what makes a sapphire engagement ring feel personal rather than generic.
Where sapphire is depth, aquamarine is light. A beryl of Mohs 7.5–8, it carries the literal color of seawater — the stone our studio took its name from — and brings an airiness the deeper blues cannot. For those drawn to the luminous rather than the saturated, an aquamarine engagement ring is the natural home of that preference. Nearby sit the bright, lively blues of topaz and, at the blue-green border, the teal and Montana sapphires that have become the signature of modern alternative bridal. Not every blue is mined, either — blue sandstone, sometimes sold as goldstone, is a copper-crystal artisan material prized for the starlit shimmer inside it, and we name it honestly as exactly that in our blue sandstone jewelry.
The Best Blue Gemstones for Rings
For a ring worn daily, blue sapphire's Mohs 9 hardness makes it the safest and most enduring choice, with teal and Montana sapphires offering the same toughness in a more modern blue-green. Aquamarine suits a softer, sea-blue aesthetic but asks for a little more care at Mohs 7.5–8. The decision is really one of mood — depth versus light — more than durability alone.
Below sapphire and topaz the blues get softer and ask for more thought. Tanzanite sits at Mohs 6–7, and turquoise and lapis lazuli at 5–6, so all three do best in protective settings — bezels and halos rather than high, exposed solitaires. If you would rather start from the setting than the stone, browse every colored stone we set.
Setting Blue Gemstone Jewelry in Metal
Cool metals are blue's natural companions — white gold and sterling silver let a sapphire or aquamarine read true, while a warm yellow gold vermeil throws the blue into vivid relief for those who want contrast rather than harmony. Our precious metal guide walks through the trade-off in more detail.
The metals themselves are straightforward. 925 sterling silver is a solid alloy — 92.5% silver with 7.5% copper — so it is the same metal all the way through. 14K gold vermeil bonds a 2.5 micron layer of 10K or finer gold to that same sterling core, the minimum thickness the FTC requires for the vermeil name, and solid 14K gold is 58.5% pure and stamped 585. Solid gold and platinum pieces are made to order in three to six weeks.
