Ill let you into a little secret.
IMO it is all the same thing. Firstly it varies in colour, from light sandy to more golden we see above, to even a creamier or greyer colour. It is all pretty transclucent.
As for smell, either theres different batches, but the stuff ive been taking this year hardly smells at all. A mild aroma when crushed down and that is it really, unless your getting it very new possibly. Sometimes ive seen it even look slightly damp, but I would quite happily sit here and tell you it is all the same thing.
The white/pale yellow is a different crystal entirley, but all that light beigey, golden transparent stuff, is the same thing.
So how it varies to you and what you think of it is a new one on me, that reads a joke no? lol.
