I have to say something about this because this drives me absolutely nuts! It is one of my pet peeves with the world, and I do believe the cause of it is ignorance. Let this post dispel the ignorance!
There is this wonderful stone called Ulexite that I love! It is beautiful, semi-transparent, very soft and looks very similar to a piece of cloudy Selenite. And that, my darlings, is what drives me crazy. I get into an argument with people about this mineral often. There are those selling Ulexite as Selenite. There are those who believe that Ulexite is Selenite. There are those who can’t believe that this “low-grade selenite” is as expensive as it is. The thing is that they are VERY different stones.
Ulexite has a chemical composition of NaCaB5O6(OH)6•5(H2O), aka hydrated sodium calcium borate hydroxide and was discovered by Georg Ludwig Ulex in the 1800s. It is only transparent to white. What is special about Ulexite is that it has a secondary name, the TV Stone, because of its ability to project what is beneath it to the top of the stone. This means you can read through Ulexite. It acts as a natural fibre optic.
Selenite has a chemical composition of CaSO4·2H2O, aka Hydrous Calcium Sulfate, and is a form of gypsum. It comes in various colours and types – from white to gray to brown to orange depending on the variety. Selenite comes commonly from Madagascar and Morroco whereas Ulexite is from the USA (California and Nevada), Chile, and Kazakhstan. Selenite has been known for a much longer time in modern day history – from at least the 15th century.
While both stones look similar and can feel similar – both are often white, and both are scratchable with a finger nail being only a 2 on the Mohs scale they look quite different once you know them, and they act quite differently. Selenite is usually long and fibrous, leaving a soft trail of minerals behind it unless its cut and polished. Then it is rare to find one that is transparent in my experience, at least as transparent as Ulexite. The ultimate test for ulexite is if you can read through it, even at an angle in my opinion and how soft it is. When you look at the side of a flat piece of ulexite you can see that the fibres go up and down, not side to side or any other direction. This is the way the stone must be cut in order for the projection to occur.
Both will dissolve slowly in water too! So be careful cleaning those crystals!
On a metaphysical level they both do different things as well.
Selenite is well known for its connection to the moon – the name means stone of the moon. It was once believed that Selenite wax and waned with the moon. This mineral can tune us into Mother Nature’s own cycles – which is very important for city dwellers, provide us with clarity, strengthen intuition and help with dream work. It is a self-clearing mineral that will constantly clear your energy field and help calm the mind down. It has a very gentle relaxing energy to its presence.
Ulexite is known for its clairvoyant and telepathy abilities. It needs to be cleared and easily absorbs the energy around it to the point that it may break (this has happened with one of my pieces). Ulexite will help you develop your psychic abilities and can be programmed to call up on the Angels and other Guides. It will help you learn to read the energy around you, and help you learn to manage your energy.
I actually use Ulexite pieces to do very special psychic readings because of their ability to absorb the energy of the client to such a high degree that I am able to tune in like a radio to give impressions. However, these readings as of yet, are usually very abstract and symbolic – taking another’s subconscious language and translating it is a bit tricky.
Very different stones. Both are wonderful stones.
There is an article here about a form of gypsum that is being sold as ulexite as well (I realize now I’ve seen this before).
