Selenite is the transparent crystalline variety of gypsum, a hydrated calcium sulfate that scores 2 on the Mohs scale and splits into mirror bright sheets along one perfect cleavage. Buyers shop this material in two registers, the crystallised specimen recovered from a cave or a geode pocket and the polished tower, wand or lamp turned from fibrous satin spar, and Astro Gallery of Gems names which of the two every listing holds. Astro Gallery weighs, photographs and prices each of the 36 pieces here as an individual object, because a mineral this soft carries its own history of handling.
Form settles most of a gypsum purchase, since one mineral arrives on a shelf as a crystallised specimen, as a polished object, or as a lit lamp. Astro Gallery separates those routes on the listing, so the tier you choose fixes both the price and the handling a piece demands.
| Format | What occupies it and who buys at that level |
|---|---|
| Polished point or tower, 1.7 to 2.5 lbs | Moroccan orange gypsum ground to four faces and a soft apex, the tier that carries most first purchases because each piece stands unaided on a desk. |
| Polished freeform, around 2 to 2.2 lbs | Moroccan material cut to follow its own outline instead of a geometric plan, which suits a shelf where a square base would read as imposed. |
| Blade on matrix, 2.45 to 13.6 lbs | Brazilian gypsum blades seated on quartz or basalt from Rio Grande do Sul, bought as cabinet specimens where matrix and contact matter as much as the crystal. |
| Loose cave crystal | Transparent Mexican individuals recovered from a working pocket, chosen for optical clarity and internal twinning rather than for shelf presence. |
| Satin spar wand, sphere or lamp | Fibrous gypsum turned on a lathe or drilled for a low wattage bulb, priced as a finished object and the lightest format to post overseas. |
Most towers, wands and lamps sold as selenite across the wider market are satin spar, the fibrous variety of the same gypsum species. Astro Gallery states the variety plainly on every description, since the two behave differently under light, under a lathe and under a wet cloth.
Gypsum forms wherever brine evaporates or sulfate rich water passes through limestone, so the commercial deposits sit in deserts, in old salt basins and inside flooded caves. Four sources account for everything Astro Gallery currently holds on this page.
Each row below describes one physical piece photographed as it will arrive, and the price comes straight from the catalogue rather than from a printed schedule. A specimen that sells leaves this table instead of remaining as something you cannot add to cart.

Soft minerals collect damage on the way to a shelf, and gypsum records every incident. These four faults appear in the listing images rather than needing the piece in hand.
Gypsum sits at Mohs 2, below a fingernail at 2.5, so a blade marks under a thumbnail and a polished tower picks up a scuff from a ring or a watch strap. Water does the greater damage, since gypsum is slightly soluble and a rinsed surface dries chalky where the fibres have opened. Dust each piece dry with a soft brush, keep gypsum away from sinks, humid bathrooms and open windows, and never place a wand in an ultrasonic tank, a salt bowl or a bowl of water. Astro Gallery stores this material flat and dry, and packs it in the same condition it was catalogued in.
Two audiences reach this page and one set of documentation serves both. Interior buyers use a satin spar tower as a pale vertical accent against dark shelving, group desert roses in odd numbers on a console, or run a drilled lamp at low wattage so the fibres glow from within. Metaphysical buyers work from a different vocabulary altogether, describing selenite as a cleansing or charging stone, associating it with the crown chakra, and naming it after Selene, the Greek moon goddess whose name the mineral carries.
Astro Gallery of Gems catalogues these pieces as mineral specimens and decorative objects, records variety, weight and locality on every listing, and makes no health, healing or energetic claim for any of them. Teachers and parents buy the Brazilian blades for a different reason again, since a single specimen demonstrates cleavage and hardness better than any diagram.
The price on the listing is the figure charged at secure checkout, and payment settles through Shop Pay, PayPal, Apple Pay, Google Pay, Visa, Mastercard, Discover or Diners Club. Before committing, ask our team for the height of a tower in inches, a raking light shot across a cleavage face, or the underside of a matrix specimen, and they will send those images the same working day rather than pointing you back at the listing.
Astro Gallery of Gems has packed soft minerals from its New York rooms since 1961, and gypsum receives the slowest treatment on the bench. We wrap each blade so no pressure lands on a cleavage plane, seat towers apex upward in cut foam, and double box anything above a pound. Every parcel leaves tracked and fully insured at its declared value with customs paperwork completed before dispatch, and the itemised invoice names the variety, the locality and the weight. Our returns policy and the guarantee published on about us cover each of those steps.

Buyers arriving for selenite split two ways afterwards, following either the soft mineral thread into calcite and barite or the polished form into towers and spheres cut from harder species.
