Pick the stone for how often she wears it, then the gold or silver and the setting
Start with how often she will wear it. Sapphire and ruby are hard enough for every day, so begin there for an engagement ring. Opal is soft and wants a gentler hand, yet opals were about half of what sold here, most of them light silver rings. Set in 14K gold, a stone stays tight for years. Few listings say whether the colored stone is natural, so ask us.
Find your ring size in a minute
Size 6: 16.5 mm across, 51.9 mm around. It is the most bought size here: 23 of the 87 women's gemstone rings sold here in the past year with a size recorded. 74 of the 90 rings here list size 6.
Between two sizes? Take the one that passes the knuckle and sits snug below it. A wide band, 8 mm and up, fits tighter, so go up a half size. Measure at the end of the day, at room temperature.

A screen measurement checked with a quarter is a guide, good to about a half size; the desk sizes you right the first time. "Rings here listing it" counts the live listings on October 2, 2026; the sales lines are women's gemstone rings sold here in the year to September 26, 2026, with a size recorded.
Which stone: sapphire, ruby, emerald or opal rings
Choose sapphire or ruby for a ring she never takes off. Both score 9 on the Mohs hardness scale, so desks and door handles barely mark them. Sapphire is the stone found most here, in blue, pink, red and rainbow. Emerald rates about 8, but its inner flaws let a hard knock chip it. Topaz, amethyst, citrine and garnet sit in the middle, fine for most days. Opal and pearl need the gentlest wear. For the stone of her birth month, see women's birthstone rings.
Opal: opal rings in silver and gold
Wear an opal ring for evenings and weekends, not for rough work. It is soft and can crack or scratch, so take it off to swim or lift weights. Keep perfume and ultrasonic cleaners off it. A bezel, a rim of metal around the stone, guards the edge better than prongs. Opals were about half of the rings sold in the year, and the ones bought most are light silver rings of about 2 grams. Opal in gold sits here too, most of it 14K with diamonds.
Engagement: gemstone engagement rings and solitaires
For an engagement ring, take a sapphire or a ruby in 14K gold. Sixteen solitaires here set one gemstone on a light 14K band. Each weighs between 1.8 and 2.5 grams. All of them come in yellow, white or rose gold, and nearly all run from size 4 to 8 with the half sizes. The amethyst and topaz solitaires sold best. Those stones scratch sooner than sapphire, so choose them for a ring she wears now and then. For diamonds beside the color, look at the sapphire and ruby diamond rings, or ask us about a custom piece.
Gold or silver: 14K gold or sterling silver gemstone rings
Take 14K gold for a ring she wears often. About two in three rings here are made in it, and it holds prongs tight. 18K is a richer yellow and a little softer, so it shows marks sooner. Only five rings are silver, most of them opals. Silver darkens in the air, so wipe it and store it in a closed bag. White gold cools a blue sapphire, and yellow gold warms a ruby. For karat and ring size in more depth, read the women's rings guide.
Natural or lab: natural gemstones and emerald cut rings
Ask us whether the colored stone is mined or lab-made before you pay, since few listings say. Where a description does say, it calls the stone natural, apart from one alexandrite solitaire that its title calls synthetic. Many sapphires, rubies and emeralds are heated or oiled to lift their color, which is normal, so ask what a stone has had done. An emerald cut is a step-cut rectangle that any stone can take. Two rings titled emerald hold emerald-cut diamonds and no green stone. The ones titled emerald cut ruby are rubies.
Questions we get in the store
What is the best gemstone for a ring worn every day?
Sapphire or ruby holds up best. Each scores 9 for hardness, a step below diamond, so daily knocks and scratches barely touch it. Topaz, amethyst and garnet are fine most days, while opal, pearl and emerald want gentler wear.
Are the gemstones in these rings natural or lab-created?
Few listings say, so check with us before ordering. Where a description names it, the colored stone is natural, and one alexandrite solitaire is synthetic, as its title states. Many sapphires, rubies and emeralds are heated or oiled for color.
Can I wear an opal ring every day?
You can, with care, but an opal is not a ring for rough work. The stone is soft and can crack, so remove it before a workout or a swim, and keep perfume and ultrasonic cleaners away from it.
More questions we get
What ring sizes do women's gemstone rings come in?
Most run from size 4 or 5 up to 8 or 9, with the half sizes on nearly every ring. A handful come in a single size, and the opal pinky ring runs smaller, for the little finger. Ask us for a missing size.
Is a gemstone ring a good choice for an engagement ring?
It is, when the stone is hard enough for daily wear, so choose sapphire or ruby. The colored solitaires here are light 14K rings. A softer stone such as amethyst or opal suits a ring she will not wear every single day.
Should I choose 14K gold or sterling silver for a gemstone ring?
Choose 14K gold for a ring she wears often, since it holds the stone tight for years. Silver is lighter and suits a fashion ring, like the silver opals bought most here, but it darkens and wears down faster.
Is an emerald cut ring the same as an emerald ring?
No. An emerald cut is a rectangular step-cut shape that any stone can take. Two rings here titled emerald hold emerald-cut diamonds and no green stone, so read the stone on the listing before you order, or ask us.
Can I return a gemstone ring?
Yes, inside fourteen days of arriving, unworn and unaltered. Reach customer service at service@traxnyc.com or 212-391-3832 before sending it, and it ships only on our return label. The refund policy takes out the label's cost and five percent for restocking, and custom-made or resized rings are final.
