How do I tell if my stone is selenite or satin spar?

Selenite or satin spar? These sources offer no identification test; ask for evidence of the material rather than relying on a seller's name.

How do I tell if my stone is selenite or satin spar?
Plate I — How do I tell if my stone is selenite or satin spar?

The supplied sources do not define the relationship between selenite and satin spar or provide a test to distinguish them, so this guide cannot identify your stone. The USGS lists glass and plastics among substitutes for natural gemstones and separately says simulants are frequently substituted, but that does not establish how often either material is sold as selenite.

Which evidence can settle selenite vs satin spar?

Question to resolve What the supplied evidence supports Decision for the reader
Does this guide provide a selenite–satin spar identification test? No such test is included in the supplied sources Do not use this guide to identify the specimen
Does the USGS report address gemstone substitutes? It lists glass, plastics and other substitutes and says simulants are frequently substituted Ask the seller what material is being offered and what supports that identification
Does that report establish a selenite-specific substitution rate? No selenite-specific rate is supplied Do not infer how common glass or plastic substitutions are for selenite
Does moon-goddess or cleansing lore supply identification data? The supplied material presents crystal-shop lore, not a mineral identification test Keep that lore separate from identification

The evidence gap is specific: this guide has no reference data explaining how to distinguish selenite from satin spar. That gap does not establish that no distinction or identification method exists.

What does the USGS say about glass and plastic substitutes?

The USGS lists glass, plastics, and other materials as substitutes for natural gemstones.

The same report separately states that simulants are frequently substituted for natural gemstones. That statement covers simulants generally; it is not a frequency claim about glass and plastics specifically.

The supplied USGS evidence gives no figure specific to selenite beads, so this guide does not estimate how often a bracelet sold as selenite turns out to be a simulant.

Does selenite's moon-goddess lore help identify it?

The supplied moon-goddess lore provides no test for identifying selenite. Crystal sellers including Crystal Vaults, Energy Muse and The Crystal Council describe selenite as named for the moon goddess and associate it with cleansing.

Those are crystal-shop descriptions, not historical evidence or physical measurements. They do not explain how to distinguish selenite from satin spar.

What should you ask a seller before buying a selenite bracelet?

Ask the seller which material is being offered and what evidence supports that identification. Request a mineral reference or identification report that explains the terminology and applies to the stone being sold.

If the seller provides only a name or a lore description, leave the identification unresolved rather than treating this guide's missing reference data as an answer.

FAQ

Is satin spar just another name for selenite?

The supplied sources do not define satin spar or its relationship to selenite, so this guide does not state one. Ask for a mineral reference that explains how the terms are being used.

Does the moon-goddess name prove a stone is selenite?

The supplied crystal-shop lore describes selenite as named for the moon goddess, but it provides no physical identification test or comparison with satin spar.

Can glass or plastic be sold as selenite?

The USGS lists glass and plastics among substitutes for natural gemstones and separately says simulants are frequently substituted. This general evidence does not establish whether a particular selenite listing is glass or plastic, or how common such substitutions are.
