How to measure at home
- 1. Wrap a thin strip of paper around the base of the finger you'll wear the ring on.
- 2. Mark where the paper overlaps, then measure the length in mm — that's your circumference.
- 3. Match it to the circumference column above. Measure in the evening — fingers are largest then.

Cabochon: The Oldest Cut, Explained
Before humans learned to facet — before the wheel, arguably — they polished stones into domes. The cabochon (French for the dome-shape, and older than the word by millennia) survives because it does something faceting cannot: it presents a stone's color as one unbroken pool. Light enters the dome, softens, and comes back as depth.
For a birthstone ring, that is the whole argument. You are not buying sparkle; you are wearing your month's color. The smooth dome also wears kindly — nothing to snag, nothing to chip at the corners the way a faceted stone can.
Six Months, Six Moods
March opens with aquamarine's pale sky blue — the calmest statement a ring can make. April answers in diamond white, cool and certain. May goes emerald green, deep enough to read as serious. September's sapphire blue is the formal one — the month that wears a suit. October closes the set with pink opal, the color that makes people ask about your ring rather than compliment it from across the table.
Five colors, five temperaments, one silhouette — the choosing is a small act of self-description.
Built to Be the Ring You Never Take Off
The band is genuine 925 sterling silver — hypoallergenic, nickel-free, sized 5 through 9 with the full chart below the selector. April offers its gold-band twin for warm wardrobes; every other month ships on silver. The cabochon sits low and domed, so the ring works under gloves, at the gym, and on the hand that does the dishes.
Wear it daily, wipe it occasionally, and it ages the way good silver does — a little warmer, a little more yours.

Better than expected
Ordered as a gift, was worried the aquamarine would look washed out. It doesn't - the color is delicate but visible. Stone is well-cut and sparkles.

Beautiful but runs small
The aquamarine is gorgeous - exactly the color I wanted. Sizing runs about a half size small. Exchanged for a larger size and it's perfect now.

Birthstone Cabochon Ring — Choose Your Month FAQ
The most-asked questions about this piece, answered.
Which color should I choose for my birth month?
Match the cabochon color to your month: March is sky blue (aquamarine), April is diamond white (silver or gold band), May is emerald green, September is sapphire blue, and October is pink (pink opal). Not sure of the stone for your month? Our birthstone guide lists all twelve.
What are the stones made of?
Each smooth cabochon is a polished color gemstone chosen to match its month's birthstone color, set on a genuine 925 sterling silver band. The April gold-band version is finished with 18K gold plating over the silver core.
How do I pick the right ring size?
We offer US sizes 5 through 9 — most women wear 6 to 7. The band is slightly wide, so if you are between sizes, choose the larger one. The full size chart with diameter and circumference measurements is right below the size selector.
Can I wear this ring every day?
Yes. Cabochon stones have no facets or prongs to catch — the smooth dome shape is one of the most durable everyday cuts. Wipe with a soft cloth and remove before swimming to keep the silver brightest.
Is this a good birthday gift?
It is one of the most personal birthday gifts you can give: choose the stone color of the recipient's birth month, pick the band finish, and it arrives in gift-ready packaging. Pair it with our matching cabochon styles for a complete set.
What is a cabochon ring?
A cabochon is a stone cut as a smooth polished dome — no facets, no angles — the oldest cut in jewelry, older than faceting by thousands of years. For birthstones it has one clear advantage: a cabochon shows a month’s COLOR pure and deep, where facets break color into sparkle. If you want your month seen clearly, cabochon is the honest cut.
Why does this ring come in six months, not twelve?
Six colors earn the cabochon treatment: March sky-blue aquamarine, April diamond white, May emerald green, September sapphire blue, October pink opal — plus April in a gold-band version. These are the months whose stones read best as smooth color domes; the louder, lighter months suit faceting instead.
What does pink opal mean?
October’s pink opal carries the softest reading in the birthstone calendar — emotional calm, hope, and the gentle kind of love. Pink opal rings are often chosen not by October babies alone but by anyone who wants a stone that whispers rather than announces.
What is the April gold-band version?
April’s diamond-white cabochon comes two ways: on the plain 925 silver band, or on a band finished with 18K gold plating over the silver core — the gold warms the white stone and flatters warm skin tones. Same stone, same cut, two temperaments.
Can I stack birthstone cabochon rings?
Yes — the slim band was drawn for it. Stack your month with a plain silver band, or pair two months (yours and theirs) side by side; sizes 5 through 9 cover most fingers, and the smooth dome never catches on anything a flat band would not.
