Birthstone Rings

Each of our birthstone rings starts as a design, and you finish it with three choices: the stone, the center size, and the metal. There are twelve stones to choose from, including garnet, amethyst, aquamarine, emerald, alexandrite, ruby, peridot, blue sapphire, pink tourmaline, citrine, blue topaz, and white sapphire. Metals are 14K yellow gold, 14K white gold, and 14K rose gold. The price updates as you choose, and the stone is included in the price you see.

The modern list runs garnet for January, amethyst for February, aquamarine for March, and diamond for April, where white sapphire is the usual colorless alternative. May is emerald, June is alexandrite, July is ruby, and August is peridot. September is blue sapphire, October is pink tourmaline, November is citrine, and December is blue topaz.

Plenty of people ignore the calendar entirely and choose the color they love. That is a perfectly good reason.

Blue sapphire, white sapphire, and ruby are the toughest at 9 on the Mohs scale, followed by alexandrite at 8.5 and blue topaz at 8. Aquamarine and emerald sit at 7.5 to 8, pink tourmaline at 7 to 7.5, and amethyst and citrine at 7. Garnet ranges from 6.5 to 7.5, and peridot from 6.5 to 7, so those two show wear sooner on a hand that works.

Hardness is not the whole story. Emerald almost always carries natural inclusions that make it more prone to chipping than its number suggests, so it rewards a protective setting and a little care.

A bezel. The Round Bezel-Set Solitaire and the Round Milgrain Bezel-Set Solitaire wrap the stone in a continuous rim of gold, which guards the edges that usually chip first. If you are choosing peridot, garnet, or emerald for a ring that will be worn daily, those two are the honest recommendation.

Prong and halo designs, like the Oval Halo-Style or the Trillion Halo-Style, show more of the stone and let in more light. They suit the harder stones, or anyone who takes rings off for chores and the gym.

Center sizes depend on the design and run from a delicate 2.5 mm up to 8×8 mm, with ovals offered in sizes such as 6×4 mm, 7×5 mm, and 8×6 mm. For a slim finger or a ring meant to stack, a smaller round like the Petite Round Solitaire keeps things understated. A larger oval in the Oval Classic Three-Stone or the Oval Accented Split Shank gives the color room to show its depth. Each product page lists the sizes available for that ring.

Each product page states whether the stone is natural or laboratory-grown, so you always know exactly what you are buying. Some colored stones are routinely treated to improve color or clarity, and any treatment is disclosed on the product page. If you have a preference for one or the other, check that line before you order.

Let the stone guide you. Cool stones like aquamarine, blue topaz, and blue sapphire look crisp and icy in 14K white gold. Warm stones such as citrine, garnet, and peridot glow against 14K yellow gold. 14K rose gold is a lovely, softer match for pink tourmaline and amethyst, and it gives vintage-leaning designs like the Oval Vintage-Inspired a gentle, old-world warmth.

Measure carefully, because birthstone rings are made to the ring size you choose and are final sale. Our sizing guide walks you through measuring at home, and the most reliable method is to have the finger sized by a local jeweler. Measure at the end of the day when fingers are slightly larger, and choose a half size up for wider designs like the Round Criss-Cross Accented or the split shank.

You can, with a little detective work. Borrow a ring she already wears on the same finger and have it measured, or ask a close friend or family member who might know her size. Since the ring is final sale, a guess is a real risk. If you are unsure, a birthstone necklace or earrings may be a safer surprise, and we can help you choose.

Clean it with warm water, mild dish soap, and a soft brush, then dry it with a lint-free cloth. Take it off for heavy lifting, gardening, and cleaning with household chemicals. Have the prongs or bezel checked once a year, especially on designs with small accent stones like the Round Leaf or the Oval Accented Vintage-Inspired.

Many of these rings are made to order, and each product page shows that ring's ship time. Every US order ships free with fully insured UPS Ground, and orders of $500 or more ship free by UPS Express with a signature required. Every ring also carries a lifetime warranty against manufacturing defects.
