Buy Polished Stones & Crystals Online — Choose by Room, Budget and Stone

Most people arrive here with a place in mind rather than a species: a desk that needs colour, a shelf that needs an anchor, a gift that should not need instructions. This page is built around that — match the setting first, then the stone. Astro Gallery has bought lapidary work for its Fifth Avenue shelves since 1961, and there are 180 polished pieces in stock today.

Start Here: Which Polished Stone Suits You

A desk that gets handleddaily contact, small footprintGo hard: quartz-family stone and jasper at Mohs 6.5–7 shrug off knocks, pens and coffee rings. Palm stones and small hearts sit under a pound and survive being picked up ten times a day — which they will be.
A shelf that needs an anchorone to three poundsThis is freeform and sphere territory: big enough to read across a room, light enough to lift for dusting. Pattern matters more than species here — ocean jasper’s orbs and labradorite’s flash both hold a room.
A console or mantlestatement scaleMulti-pound freeforms are bought the way small sculpture is bought: for one wall, one light, one room. Today’s 2.6-pound malachite with chrysocolla is that kind of piece — and its Congolese colour does not need a second object beside it.
A gift with no instructionsarrives readyNo batteries, no maintenance, no size to get wrong. A polished stone works as a gift precisely because it asks nothing of the recipient — and because each one is an individual object rather than a product line item.
A room with strong sunlight exposureChoose stable colour: quartz, agate and jasper hold saturation. Keep intensely coloured material — amethyst especially — off a south-facing windowsill, where months of direct light slowly pale it.

Polished Stones & Crystals for Sale — Live Prices

Every stone below was chosen by eye at the gallery, then weighed and photographed as itself. Prices are live and every weight is the actual piece’s; two freeforms of the same stone can differ by a couple of pounds, so shop the individual listing rather than the species.

What the Polish Reveals: Natural Stone, Lapidary Craft

Polishing reveals a stone; it does not create one. Lapidary work — sawing, grinding through finer and finer grits, then finishing — is the craft of letting an interior speak: banding inside an agate, orbs inside an ocean jasper, blue-gold fire inside grey labradorite that no one would guess from the rough. The material stays exactly what the earth made. Only the surface changed.

Depth of stock follows demand: 74 quartz-family listings lead, 50 pieces come from Madagascar, and character stones fill the rest — eleven agates, eleven labradorites, malachite with chrysocolla out of the DRC, lapis lazuli from Afghanistan. Judge any of them on four things: pattern (what you will actually look at for years), finish (even and mirror-bright, no flat spots or drag lines), honest colour (natural, with any treatment disclosed — dye shows strongest at cracks and chips), and weight, stated in every title.

Stone by Stone: What Each Species Actually Looks Like

Quartz familyRose (soft translucent pink), smoky (grey-brown), strawberry (pink with red inclusions), clear. Hardness 7, the workhorse of decorative stone — 74 listings today.
Ocean & polychrome jasperMadagascan, and the most patterned material here: orbs, waves and ribbons in green, cream and rust. Every cut is unrepeatable, which is why jasper sells on photograph.
LabradoriteGrey until it moves — then blue, gold and occasionally violet flash across the surface. Eleven listings today; the one stone that must be seen turning.
Malachite with chrysocollaCongolese, banded in green and cyan. Soft and copper-bearing, so a dry shelf and a light touch; visually the loudest stone in the collection.
Lapis lazuliAfghan, deep ultramarine flecked with pyrite gold — the pigment of Renaissance painting, still mined in the same valleys.
Agate & obsidianAgate for concentric banding and translucency at the edges; obsidian for volcanic glass-black with a mirror finish that reads as sculpture.

Crystal Terms: Freeform, Palm Stone, Chatoyance & Labradorescence

FreeformCut to follow the rough’s own shape rather than a geometric form — keeps the best pattern, wastes the least stone, and no two repeat.
Palm stoneAn oval finished to sit in the hand. The entry point of polished stone, and the most-handled object in most collections.
SphereSymmetry bought at the cost of material — shows a stone’s pattern from every seat in the room, and wants a stand.
ChatoyanceThe moving band of light in tiger’s eye and cat’s-eye selenite: an optical effect of fibrous structure, not a coating.
LabradorescenceLabradorite’s internal blue-gold flash, visible only at angles. Turn the stone to find it — then place it where the light will.
Ocean jasperOrb-patterned Madagascan jasper whose spheres and bands make every cut unrepeatable.

What to Expect When Your Stone Arrives

Photography is honest here, but stone still surprises people in two directions. Weight lands heavier than expected — a two-pound freeform feels like four in the hand — and natural inclusions, veins and the odd healed fracture are part of the material rather than flaws in the finish. Colour shifts with light: labradorite needs a directional source to flash, jasper reads richer under warm light than a phone screen suggests, and translucent stones want something behind them. Give a new piece a week in the room before deciding where it lives, and if it genuinely is not right, the fourteen-day window is there for exactly that.

Living With Polished Stone: Care and Buying Terms

Hard species — quartz, jasper, agate — take dusting and daily handling without complaint. Softer decorative stone such as malachite and selenite prefers a dry shelf and a light touch, and no stone enjoys months of direct sun. That is the whole maintenance schedule.

Change your mind? You have fourteen days to postmark it back in its original packing, with the refund inside two weeks of arrival or store credit straight away; return postage is yours, and anything damaged in transit needs a call the next business day. And if you would rather choose by eye, the Fifth Avenue shelves are open — the same third-generation gallery, trading since 1961, whose collection was profiled in Mineralogical Record Vol. 47 No. 4.1.

Polished Stone FAQs: Natural Stone, Prices & Choosing

Are polished stones natural?
Yes — polishing shapes the surface of a natural stone; it does not manufacture one. Each piece is cut from named rough, listed individually with its own weight and photography, and where any treatment beyond cutting and polishing applies, ask and the gallery states it plainly.
Is every polished stone one of a kind?
Effectively yes — freeforms and patterned stones are listed individually with their own weight and photographs because no two cuts repeat, and when a listing sells it retires. What you order is the piece that was photographed for that listing.
How much do polished stones cost?
The spread is wide because the stones are individual: hand-sized pieces open the range and multi-pound statement freeforms close it, with species, pattern quality and weight setting each price. Every listing shows its live price in your currency.
What is the difference between a freeform and a sphere?
A freeform follows the rough’s own geometry, so the lapidary keeps the best pattern and loses the least material; a sphere sacrifices material for symmetry that shows the pattern from every angle. Freeforms stand alone; spheres want a stand.
Which stone suits a desk or a gift?
Quartz-family pieces are the safe first pick — hard, bright and untroubled by handling. For pattern, Madagascan ocean jasper; for drama, labradorite’s flash. Tell the gallery the setting and it will shortlist with photos.
Which polished stones are safe around water and sunlight?
Quartz, agate and jasper are the durable choices — hard, stable and untroubled by damp hands or a bright room. Selenite dislikes moisture entirely, malachite prefers a dry shelf, and strongly coloured stones such as amethyst fade under months of direct sun.
Will the stone look like the photograph?
Yes — each listing shows the actual piece with its own weight. Expect it to feel heavier than it looks, and expect natural veining and inclusions, which are the material rather than defects. Labradorite in particular needs directional light to show its flash.
What are the return terms?
Return postmarked within 14 days in original condition and packaging with the packing slip; refund within two weeks of receipt or store credit immediately; return shipping on the buyer; arrival damage reported within one business day.
