Gems and Jewelry

Emerald, ruby, sapphire and tourmaline mounted in 14k gold, alongside meteorite and fossil agate set in sterling silver.

Gemstone Jewelry Priced by the Stone: Rings, Pendants, Earrings and Necklaces in 14k Gold and Sterling Silver

Gemstone jewelry is a finished wearable piece whose value is carried mainly by the mounted stone rather than by the metal holding it, which is why a 1.96 carat emerald in 14k white gold outruns a heavier band carrying nothing. Astro Gallery of Gems buys loose gem material at the cutting centres, commissions the mounting, weighs and records every centre stone in carats, and photographs each finished piece on its own, so all 121 rings, pendants, earrings and necklaces here carry a stated carat weight, metal mark and setting rather than a category average.

Why Two 14k Rings Carry Different Prices

Metal accounts for a small share of what a gem set piece costs and the centre stone accounts for most of it. Species, carat weight, colour saturation and the diamond accent work move the figure far more than whether a shank weighs three grams or five.

Price driverHow it moves the figure
Mineral speciesCorundum, the family covering both ruby and sapphire, carries the highest rate per carat here, followed by beryl as emerald, then elbaite tourmaline, with the quartz varieties at the accessible end.
Carat weightRate per carat climbs steeply with size because large clean rough is scarce, so one 2.98 carat pear cut emerald costs considerably more than three separate one carat stones.
Colour and claritySaturated colour commands the premium, while visible inclusions, known in emerald as the jardin, pull the figure down without making the stone any less natural.
Metal, diamonds and bench labourGold at 585 parts per thousand, micropave accents counted separately in points, and the hours a halo or leverback demands sit on top of the centre stone rather than setting the price.

Carat Weight to Ticket Price, Piece by Piece

Each row below is one finished piece rather than a style repeated across a size run, and the figure comes straight from the catalogue. Astro Gallery prices at gallery rate and holds that price through checkout, so a piece that sells drops out of this table instead of sitting in it unavailable.

Which Gem Species Set the Price Bands

Four mineral families cover almost everything mounted in this collection, and each behaves differently on the finger, at the bench and in a cleaning bowl. Astro Gallery buys these species as loose cut goods and then matches each stone to a mounting that suits its hardness and its habits.

Corundum: ruby and sapphireAluminium oxide at Mohs 9, harder than anything except diamond, which is why ruby studs at 1.01 to 1.75 carats and sapphire bands survive daily wear. Heat treatment is standard across the trade for both colours and is stated on the listing.
Beryl: emeraldBeryllium aluminium silicate at Mohs 7.5 to 8, hard but brittle because of the internal fissures the trade calls the jardin. Emerald is routinely oiled to soften the look of those fissures, which is accepted practice and the reason ultrasonic cleaning is never used on it.
Elbaite tourmalineA complex boron silicate at Mohs 7 to 7.5, cut here in pink and green at weights reaching 13.2 carats. Minas Gerais in Brazil supplies most of the world's gem elbaite, and large clean stones of that size come out of that pipeline rather than from any other.
Quartz varieties and iron meteoriteAmethyst, citrine and smoky quartz are all silicon dioxide at Mohs 7, worked here from 4mm beads up to 6.7 carat centres. Sterling silver pieces also carry Muonionalusta and Seymchan iron, etched to bring up the Widmanstatten pattern.

The Four Failure Points in a Gem Set Mounting

Trouble in gem set jewelry shows up in four predictable places, and every one of them is visible in a listing photograph or answerable by email before any money changes hands.

The metal markConfirm the listing states 14k gold or sterling silver 925 rather than gold tone or gold filled. Astro Gallery records the karat mark on every piece and photographs the hallmark itself whenever a buyer asks for it.
Stone weight against stone sizeA stated carat figure should agree with the millimetre dimension given for the stone or the pendant. A 6.7 carat amethyst in a 16mm pendant is consistent, and any mismatch between those two numbers deserves a question before payment.
How the girdle is heldProngs, bezel and micropave grains each grip a stone differently. Prongs should sit flush and evenly spaced in the photograph, because a lifted prong is the commonest single cause of a lost centre stone in a mounted piece.
Treatment disclosureHeat in corundum and oil in emerald are normal and stable enough for ordinary wear. Astro Gallery states any treatment it knows of in the description rather than leaving a buyer to work it out from the price.

Ring Sizing, Resizing and Chain Length

Rings arrive at a stated size, currently 6.5, 7 and 7.5 across the gold pieces and 6 3/4 in sterling silver, and that number appears in the listing before you buy. A plain gold or silver shank takes resizing at a bench jeweller within roughly two sizes in either direction.

A band set with micropave diamonds running the full circumference resists resizing, because cutting the shank distorts the grain work holding those small stones. Pendants ship on an 18 inch chain unless the listing gives another length, and Astro Gallery will measure the inside diameter in millimetres so you can check it against a ring you already wear.

Wear It Every Day or Buy It for the Stone

Two buyers reach these listings from opposite directions, and the same piece can satisfy either one, so the deciding question is whether hardness and setting security matter more to you than carat weight and colour.

The daily wear pieceCorundum studs and sapphire bands at Mohs 9 shrug off contact with door handles, desks and keyboards, and a bezel or micropave mount keeps the stone low against the finger. Anyone buying jewelry they intend never to take off should choose ruby, sapphire or a quartz variety in a protective setting.
The stone led purchaseA 13.2 carat pink tourmaline pendant or a 2.98 carat pear cut emerald ring is bought for the crystal first and worn on chosen occasions. These pieces suit a collector who already buys loose gem material, and their carat value holds independently of fashion in mountings.

Micropave, Bail and Jardin Explained

Karat and 58514k gold contains 585 parts gold per thousand, giving a harder and more scratch resistant alloy than 18k while holding a warm colour.
MicropaveA setting in which small diamonds are held by raised beads of metal worked under a microscope, producing a continuous line of light around a centre stone.
BailThe loop at the top of a pendant through which the chain passes. Several pendants here carry diamond accents set into the bail itself.
JardinThe network of internal fissures inside emerald, treated by the trade as a characteristic of the species rather than as damage, and the reason emerald is oiled.
LeverbackAn earring fitting that closes on a hinged lever behind the lobe, holding more securely than a butterfly back and preferred on drop earrings carrying weight.
Widmanstatten patternThe interlocking crystal figure inside an iron meteorite, revealed by cutting, polishing and acid etching, and the reason meteorite slices are set into pendants and rings.

Cleaning Gem Set Gold and Silver at Home

Warm water, a drop of dish soap and a soft toothbrush clean 14k gold set with corundum or quartz, and drying on a lint free cloth brings the polish back. Emerald is the exception here: keep it out of ultrasonic tanks and steamers, both of which strip oil from the jardin and leave a clear stone looking hazy. Sterling silver darkens as copper in the alloy reacts with sulphur in the air, so store it closed away and lift tarnish with a silver cloth rather than a dip, which attacks porous stones.

Gifting, Inheritance and the Stone Lore Buyers Bring

Gem set jewelry moves for engagements, anniversaries, graduations and birthdays, and the birthstone calendar drives a large share of that demand: garnet, amethyst, emerald, ruby, peridot and sapphire each own a month. Buyers also arrive using the vocabulary of the crystal trade, choosing amethyst for calm, rose quartz for the heart chakra and citrine for abundance. Astro Gallery documents species, carat weight, metal and treatment on every listing and makes no health or energetic claim.

Sizing, Metal and Shipping Answered Before Checkout

How much does a gemstone ring cost here?
Sterling silver pieces set with peridot or citrine open the range, gold mounted amethyst and tourmaline pendants occupy the middle, and diamond accented emerald and ruby pieces in 14k white gold sit at the top. The table above carries live figures for everything currently in stock, and each one refers to that individual piece.
Are the gemstones natural or laboratory grown?
Every stone mounted in this collection is natural gem material cut from mined rough. Astro Gallery names the species in the title, states heat or oil treatment in the description, and photographs each piece individually, so the stone you see is the stone that ships.
What ring size do these come in, and can they be resized?
Ring sizes appear in the listing, currently 6.5, 7 and 7.5 in gold and 6 3/4 in sterling silver. A plain shank resizes at a bench jeweller within about two sizes either way, while a band carrying micropave diamonds all the way round should be bought at the size stated.
Is the gold real, and what karat is it?
The gold pieces are 14k, meaning 585 parts gold per thousand, and the silver pieces are sterling at 925. Astro Gallery records the karat mark on every listing and will photograph the hallmark on the piece itself before you commit to it.
Do pendants come with a chain?
Yes, gold pendants ship on an 18 inch 14k gold chain, and the meteorite and fossil agate pendants ship on an 18 inch sterling silver necklace, with the length stated in each listing. Beaded necklaces are strung at 18 or 22 inches on elastic cord.
How do I clean an emerald ring safely?
Use warm water, a drop of dish soap and a soft brush, then dry it on a lint free cloth. Keep emerald away from ultrasonic cleaners and steam, because both remove the oil filling the jardin and leave the stone looking cloudy.
Do you ship jewelry internationally?
Yes, every order travels tracked and fully insured worldwide, packed in a fitted box inside an outer carton, with customs paperwork completed before dispatch and the declared value matching the invoice.
What happens if the ring does not fit?
Return it under the terms published on our returns page. Asking us for the inside diameter in millimetres beforehand settles the question for most buyers, because that measurement can be checked against a ring already in the drawer.

Where Gem Set Jewelry Meets the Rest of the Catalogue

Buyers who came for a species usually want to see it loose as well as mounted, while buyers who came for a format move sideways into silver, meteorite and gift pieces. These groups cover both routes out of this page.
