Unlike stones with shiny surfaces often seen on Amazon and elsewhere, these stones have no chemical waxes or coatings. Basalt cannot be brought to a natural shine without the use of waxes or epoxy resins. A non-shiny surface is a guarantee that your stones are 100% natural. Most basalt that is suitable for use in hot stone massage is grey (most black basalt, with a few exceptions, is too coarse and grainy for use as massage stones) but turns black after it has been oiled. Stones treated with waxes or epoxy resins have in the vast majority of cases turned black because of the coating.
