It was pretty fiddly getting the letters just right. Teeny tiny faults in the quality of line or shape make the whole thing look awkward, so I took my time getting the shapes perfect.
The surface is sanded down to 800-grit paper and then polished on the bench polisher. To see what that looks like, go here. (This page I have doesn't let me put videos right in posts yet.)
Carving a hole and groove into an ancient, fossil-bearing stone initially felt sacrilegious. But I've decided that they are better being used in jewellery, even if it means altering them such as I have here. Fossil worm casts in argillite are actually quite common among the beach stones at Orepuki. I have a another couple of stones like this in my collection currently, and I have used a few more in jewellery. They are out in the wide world being loved and appreciated right now, rather than stowed away in a shoebox being too precious to use.
