Obelisks and Pyramids

Malachite, labradorite, tiger's eye and Madagascan jasper, ground square at the base and tapered to a point.

Buy Agate Obelisks and Polished Stone Towers, Priced by Height, Weight and Cut

An obelisk is a four sided stone tower that a cutter grinds square at the base and tapers to an apex, so whatever the stone does best, banding, flash or orbs, climbs all four faces and concentrates as the form narrows. Astro Gallery of Gems buys this material at the block stage in Katanga, Madagascar and Minas Gerais, commissions the cutting, and photographs every finished tower, point and pyramid individually, so each of the 15 towers, points and pyramids on this page carries its own weight, height and grain rather than repeating a production line.

How a Block Becomes a Tower You Can Buy

A tower is made twice: once by geology and once by a cutter who decides where the pattern will land. Astro Gallery buys rough where the banding or schiller is already visible on a sawn face, then has the block oriented so that figure climbs the finished piece instead of running out halfway up. That decision, made months before a tower reaches this page, is what separates a stone that holds a room from one that merely stands in it.

Katanga malachiteCopper carbonate from the Kolwezi belt in the Democratic Republic of Congo, banded in concentric green eyes that tighten as the taper climbs. It measures Mohs 3.5 to 4 and carries real density, which is why these towers pass sixteen pounds and command the highest prices here.
Madagascan labradoritePlagioclase feldspar from the Tulear region, oriented on the wheel so the blue and gold schiller ignites across one face and disappears from the next. At Mohs 6 to 6.5 it takes daily handling, and because the flash is directional it rewards a position people walk past.
Tiger's eye and Brazilian rose quartzChatoyant crocidolite fibres throw a moving band of gold across tiger's eye, while Minas Gerais rose quartz clouds softly with microscopic rutile. Both are quartz at Mohs 7, both finish under cerium oxide to a mirror, and both warm noticeably against oak and walnut.
Madagascan jasperOrbicular ocean jasper from the Marovato coast and polychrome jasper in reds, golds and greens. This chalcedony sits at Mohs 6.5 to 7 and carries the busiest patterning in the collection, so every pyramid resolves differently and the photograph becomes the specification.

Height Decides the Room Before the Stone Does

Most buyers arrive knowing where a piece will stand before they know what it should be made of. Weight and height settle whether a tower reads as a desk object, a shelf object or a floor object, and the material follows from that. These four tiers cover everything currently cut.

TierWhat sits in it and who buys it
Mini pyramid, 10 to 20 gramsPyrite, green aventurine and amazonite measuring roughly an inch across the base, which collectors group in threes on a desk and which carry most of the gift buying here.
Desk point or pyramid, 100 grams to 1.5 lbsBrazilian chevron amethyst points and Madagascan ocean jasper pyramids that hold paper down, survive a working desk and still fit a crowded shelf.
Shelf obelisk, 1 to 5 lbsRose quartz from Brazil and labradorite from Madagascar, the tier that carries most first tower purchases and the easiest to place in a finished room.
Statement tower, 16 lbs and upKatanga malachite obelisks and a tiger's eye tower measured in feet, which anchor a console or a floor position and need a cleared sight line to work.

Obelisk, Tower, Generator or Point: One Form, Four Names

Buyers reach this form through different vocabularies, and the words matter more for searching than for cutting. Lapidary and interior sellers call a four sided tapered piece an obelisk or a tower, while metaphysical sellers describe the same object as a generator or a standing point. Astro Gallery states material, weight and cut on every listing so the terminology never decides what arrives at your door.

The tower or obeliskA tall narrow form whose four faces meet at one apex, which draws the eye upward and holds a shelf on its own. Labradorite and malachite earn this treatment because height gives their flash and banding room to develop. It asks for clearance above and a surface that will not flex beneath it.
The pyramid or pointA low, wide, stable form that resists knocking over and photographs well in odd numbered groups. Because pyramids begin at gram weights and travel safely, they carry the entry pricing and most of the gifting, while points sit between the two on both height and cost.

Four Things Worth Checking Before You Commit

Lapidary shortcuts surface in the same four places on every tower, and each one shows clearly in the listing photographs rather than needing the piece in hand.

Base squarenessA tower that rocks was ground off square. Astro Gallery flattens and stands every base on a level surface before listing it and photographs the underside, so you can confirm the grind rather than trusting a description.
Taper symmetrySight down onto the apex from directly above and the four faces should converge on a single point rather than a short ridge. That ridge is the commonest shortcut in inexpensive cutting because it saves grinding time on the last few millimetres.
Polish depthStudy a reflected light travelling across a face at a shallow angle. A cerium oxide finish returns that line unbroken, whereas a rushed polish reveals orange peel texture and dulls noticeably where the face meets the edge.
Pattern placement and honestyBanding, schiller and orbs should climb the face rather than pool in one corner, and natural colour should run right through a chip or an edge. Dyed material concentrates at the surface and pales the moment you look at a broken edge.

Reading a Tower Listing

ApexThe point where the four tapered faces converge, and the clearest single marker of cutting quality on any tower.
TaperThe rate at which the form narrows. A steep taper visually shortens a piece, while a slow taper makes the same height read considerably taller.
SchillerThe metallic flash inside labradorite, produced when light rebounds off microscopic layers within the feldspar rather than off the polished surface.
ChatoyancyThe moving band of light crossing tiger's eye, generated by parallel crocidolite fibres and shifting as either you or the light source moves.
OrbicularThe circular patterning that defines ocean jasper, formed by radiating mineral growth and graded on the roundness and contrast of the orbs.
UndercutA slight bevel ground into the bottom edge so a tower seats flush against a shelf and resists chipping on a hard surface.

Placing a Tower: Interiors, Gifting and the Metaphysical Trade

Two distinct audiences buy these pieces and both are served by the same documentation. Interior buyers use a crystal tower as a vertical accent, breaking a long run of horizontal books, anchoring a console with an odd numbered group of pyramids, or positioning labradorite along a walking line so the schiller fires as someone passes. Metaphysical buyers work from the stone rather than the silhouette, choosing rose quartz for the heart chakra, malachite for protection, tiger's eye for grounding and amethyst for calm.

Astro Gallery sells these objects as mineral specimens and decor, documents locality, weight and treatment on every listing, and makes no health or energetic claims about any of them. Naming the vocabulary buyers actually use costs nothing; overstating what a stone does would cost the trust that sixty five years of dealing has built.

Keeping a Polished Tower in Condition

Malachite governs the care routine here because it is the softest and most reactive stone on the page. At Mohs 3.5 to 4 it marks under a fingernail, and as a copper carbonate it responds badly to acids, so dust it dry with a soft cloth and keep vinegar, household sprays and standing water away from the polish permanently. Rose quartz fades across months on a south facing sill and belongs out of direct sun, while labradorite, tiger's eye and the jaspers absorb ordinary handling and ask for nothing beyond dusting. Any tower above ten pounds concentrates its entire weight on a small square base, so choose a surface that carries point loading and slip a felt pad underneath to protect a polished shelf.

Ordering, Packing and Worldwide Delivery

Buying works identically whether you choose a fourteen gram pyrite pyramid or a sixteen pound malachite tower: the listed price is the price charged, and checkout settles through Shop Pay, PayPal, Apple Pay, Google Pay or card. Before committing, ask us for the exact height in inches, a photograph of the base grind, or a short clip showing how the schiller travels under a moving lamp, and our team will send it rather than pointing you back at the listing.

Astro Gallery of Gems has packed stone for transit since 1961, and the method reflects it. We isolate the apex in cut foam so no pressure ever reaches the tip, block the base so the weight cannot travel inside the carton, and double box everything above a pound. Every parcel leaves tracked and fully insured to any destination with customs paperwork completed in advance, and the heaviest malachite and tiger's eye towers move by freight against a quote we agree with you beforehand. Our invoice, the returns policy and the guarantee published on about us stand behind every one of those steps.

Questions Buyers Ask Before Ordering a Stone Tower

Are these obelisks actually agate?
The towers cut for this collection are malachite, labradorite, tiger's eye, rose quartz, chevron amethyst and Madagascan ocean and polychrome jasper. Agate and chalcedony pieces join the group whenever we cut them, and because we name the species on every listing you never have to guess which material you are buying.
How much does a crystal obelisk cost?
Mini gemstone pyramids at gram weights open the range, desk pyramids and points occupy the middle, and large Katanga malachite towers sit at the top. The table above carries live prices for everything currently in stock, and each figure reflects that individual piece rather than a category average.
What is the difference between an obelisk, a generator and a point?
All three describe the same tapered form through different trade vocabularies. Lapidary and interior sellers say obelisk or tower, metaphysical sellers say generator or standing point, and a point usually refers to a shorter piece finished from natural crystal. We specify material, weight and cut so the label never changes what ships.
Will a tall tower stand on its own without a base?
Yes. We grind every base flat and stand each piece on a level surface before it goes online, then photograph the underside so you can verify the finish. No stand, wedge or adhesive is required for any tower in this collection.
Is the piece in the photograph the one I receive?
Yes. We photograph each tower individually because no two blocks of malachite or ocean jasper resolve the same way, so the banding, flash and orbs you see are the ones that arrive.
How do I clean a malachite obelisk safely?
Dust it dry with a soft cloth and nothing else. Malachite is a soft copper carbonate that reacts to acids, so water, vinegar and household sprays will dull the polish and can etch the surface permanently.
Which size suits a bookshelf?
Choose the one to five pound tier, which covers the Brazilian rose quartz and Madagascan labradorite towers and sits comfortably beside books. Anything above sixteen pounds becomes a console or floor piece and needs clearance around it to read properly.
Do you ship large towers internationally?
Yes. Every order travels tracked and fully insured worldwide with customs paperwork prepared before dispatch, and we quote freight separately for the heaviest towers so you approve that cost before committing.
Can I return a tower that does not suit the room?
Yes, under the terms published on our returns page. Requesting the exact height and additional photographs beforehand resolves the question for most buyers before a piece ever ships.

Where These Towers Sit in the Wider Catalogue

Obelisks overlap with several polished stone groups, so the useful question is whether the silhouette or the species matters more to you. Buyers chasing a shape move sideways into points, spheres and hearts, while buyers chasing a stone follow malachite or rose quartz across every form we cut it in.
