Eudialite (Eudialyte) Slabs
Eudialite is only found in cuttable form in two places:
Canada and Russia. Most Eudialite comes from Russia, but unfortunately,
it has been mined out. We brought these few slabs out of our "reserves"
to offer for sale. If you want any Russian Eudialite, now is the time
to get it. Eudialite is relatively soft and has cleavage fractures.
Therefore, it is not a material for the amateur or faint of heart.
However, it does cut gorgeous gems.
Eudialite polishes well with aluminum or tin oxide and diamond. MOHs
hardness is 5 to 5.5.
