Scrimshaw On Shell PendantsScrimshaw Pendants Handmade by Raluca on a Quahoag Shell Pendant made by another local company, Selkies. A brief overview from Raluca Scrimshaw on shells is quite difficult since it is a very hard material compared to traditional ones. I am able to use metal high speed steel engraving tools, which enable me to have high detail by stippling and also great results no matter the type of shell. I do all of my scrimshaw by hand under magnification.
