Shop Gemstone Rings by Stone Hardness, Setting and Finger Size

A gemstone ring is a cut stone mounted on a band and worn on the hand, so stone hardness and setting security decide how long it survives. Astro Gallery of Gems states the species, carat weight, metal and finger size on every ring listing. Sterling silver rings set with amethyst, turquoise and lapis lazuli open the range, iron meteorite bands sit above them, and 14k white gold rings holding ruby, emerald, sapphire and pink tourmaline top it. Buy on hardness, then on fit.

Four Things That Decide Whether a Gemstone Ring Survives Daily Wear

Fit is printed in every listing title here. Hardness is the harder question, because a ring absorbs more abuse than any other piece in the jewellery range. Four checks separate a daily ring from an occasion ring.

Mohs hardness of the stoneRuby and sapphire are corundum at Mohs 9 and shrug off airborne dust, which is quartz at Mohs 7. Turquoise at Mohs 5 to 6 abrades against that dust, so it suits lighter wear.
Setting type and prong securityA prong setting grips a gemstone with four or six claws, while a bezel wraps the girdle in a rim of metal. Prongs show more stone and snag more on fabric, so read the side photograph before you buy.
Toughness against hardnessEmerald rates 7.5 to 8 on Mohs and still chips, because the jardin of internal fractures gives an impact somewhere to travel. Hardness resists scratching, toughness resists breaking, and a ring needs both.
Band metal and printed sizeSterling silver runs 925 parts per thousand and sits softer than 14k gold, so a silver band deforms sooner. Check the printed ring size against a band you already wear, because a loose ring knocks harder.

Stone Hardness Against the Knocks a Hand Takes

Occasion or daily is settled first by the Mohs scale, which ranks scratch resistance from talc at one to diamond at ten. The working threshold for a ring worn every day sits at seven.

Stone in the ringSpecies, chemistry and MohsWhat it means for wear
Ruby and sapphireCorundum, aluminium oxide, Mohs 9.The hardest gems mounted here and the safest centre stone for daily wear. More in ruby.
Pink tourmalineComplex borosilicate, Mohs 7 to 7.5.Takes regular wear, though a 9.2 carat centre stone rides high and catches on cuffs. Compare tourmaline.
EmeraldBeryl, beryllium aluminium silicate, Mohs 7.5 to 8.Hard but brittle, so a pear cut emerald ring earns occasion status. More in emerald.
AmethystQuartz, silicon dioxide, Mohs 7.Wearable daily in a silver mount, with a purple that pales under long sun exposure. See amethyst.
Turquoise and lapis lazuliHydrated copper aluminium phosphate, Mohs 5 to 6, and lazurite rock, Mohs 5 to 5.5.Both scratch and both stain, so these rings suit a hand that stays dry.
Iron meteoriteKamacite and taenite, an iron nickel alloy.Metal rather than gem, so a meteorite ring dents and rusts rather than chipping. Origin material sits in meteorites.

Everyday Ring or Occasion Ring?

A ring worn every dayPick corundum at Mohs 9 in a bezel or a low halo, sized snug so the band does not spin. Ruby and sapphire rings in 14k white gold answer this, and they stack against a bracelet on the same wrist.
A ring kept for occasionsEmerald, turquoise and lapis lazuli reward a raised setting and a larger stone, because an occasion ring comes off between wearings. Match one to a necklace in the same stone.

Metals, Settings and Stones Stocked Here

Metal under the stone decides the other half of a ring. Alloy and setting are fixed by the maker long before a ring reaches a counter, and both print on the listing. Astro Gallery buys finished rings and prices each one individually.

14k white gold with diamond accents14k gold runs 58.5 percent fine gold, alloyed harder than 18k and finished white with rhodium. The halo rings here frame a centre gem with round brilliant diamonds, and the two carat weights print separately.
Sterling silver bandsSterling silver is 925 parts silver to 75 parts copper, softer than gold and quick to tarnish against skin oils. It carries the turquoise, lapis lazuli and amethyst rings. Compare the silver jewellery range.
Iron meteorite bandsSeymchan iron from the Hekandue river bed in the Magadan district of Russia and Campo del Cielo iron from the Chaco border in Argentina both carry the Widmanstätten pattern, stated on each ring listing.
What a ring listing statesStone species, carat weight, metal, ring size and country of origin, on one physical ring with its own photographs. Everything Astro Gallery sells is authentic. The gallery does not sell replicas or casts.
Every ring here is a single pieceThe stone, the carat weight and the finger size in the photograph are the ones that arrive, because no ring is stocked as a run of sizes.

Shop Rings by Stone, Carat Weight and Price

Price on a gemstone ring tracks the centre stone first and the metal second, so a silver amethyst ring and a 14k white gold ruby ring land at opposite ends. Shop online and the table below reads live from the catalogue.

Terms Printed on a Ring Listing

Ring sizeThe US numeric scale for the internal diameter of a band. A size 7 ring measures about 17.3 millimetres inside, and each full size adds roughly 0.8 millimetres.
Carat weightThe mass of a gemstone, one carat being 0.2 grams. A ring listing states the centre stone and the diamond accents as separate figures.
HaloA circle of small diamonds set around a larger centre gem. The halo lifts apparent size and shields the girdle of the centre stone from side knocks.
Mohs hardnessA ten point scratch resistance scale used across the gem trade. Anything under seven abrades against airborne quartz dust, which is why turquoise rings suit lighter wear.
Widmanstätten patternThe crossed band structure inside an iron meteorite, formed as kamacite and taenite unmixed across millions of years. The pattern shows on the Seymchan and Campo del Cielo ring faces.
BirthstoneA gem assigned to a calendar month by trade convention. Amethyst, emerald, ruby and sapphire each carry one, and the birthstones collection groups rings by month.

Ring Sizes, Resizing and Everyday Care

Ring size is fixed on each piece and printed in the title, with the range running from 6.5 through 10.5. Measure a finger by wrapping a paper strip around it, marking the overlap and dividing the millimetre length by 3.14 for the diameter. A jeweller opens or closes a plain silver band by about a size, though a halo mounting resists resizing.

Resizing aside, care follows the softest component in a ring rather than the hardest. Take a turquoise or lapis lazuli ring off before washing, since both are porous and soap film dulls the polish. Clean a corundum or quartz ring in warm water with a soft brush worked behind the setting, where grease collects. Keep ultrasonic cleaners away from emerald and dry an iron meteorite band completely.

Ring Questions Buyers Ask Before Checkout

How much does a gemstone ring cost?
Sterling silver rings set with amethyst open the range, and 14k white gold rings with ruby or emerald centres cost many times that. Live prices for every ring in stock sit in the table above.
Which gemstone suits an everyday ring?
Ruby and sapphire, because both are corundum at Mohs 9 and resist the quartz dust that scratches softer stones. Amethyst at Mohs 7 also holds up, while turquoise at Mohs 5 to 6 belongs on an occasion ring.
Can these rings be resized?
A plain sterling silver band opens or closes at a jeweller by about one size. Halo mountings resist resizing because the small diamonds shift, so buy the printed size and ask the gallery for the internal diameter first.
Are the gemstones in these rings real?
Astro Gallery states that everything it sells is authentic and that it does not sell replicas or casts. Stone species, carat weight and metal appear on each ring listing, and the gallery answers treatment questions on a named piece.
What ring sizes are in stock?
Sizes print in each listing title and run from 6.5 through 10.5, with the sterling silver men's rings at the larger end. Each ring is a single piece in a single size.
Do prongs loosen over time?
Prong tips thin against fabric across years of daily wear, which is why a bezel or a low halo suits a ring worn constantly. Ask for a side photograph of the setting before you order.
What is a meteorite ring made of?
Iron nickel alloy, specifically kamacite and taenite, cut from Seymchan material found in the Magadan district of Russia or Campo del Cielo material from northern Argentina. Both carry the Widmanstätten pattern on the face.
What if the ring does not fit?
Website purchases are refunded in full on safe return in original condition, postmarked within 14 days of purchase. Full terms sit on the returns page.
