Jade is a stone that can have a huge amount of texture or practically none depending on the size of the fibers that the Jade is composed of. Most Jade that is sold commercially is treated with hard waxes while the Jade is hot so that it will take a glossy polish. I am not set up to do that and putting a finished knife into a vat of hot water and then into a vat of hot wax would probably not be a good idea! I have become very good at getting a very good polish on Jade with Diamond wheels, Fabulstre and ZAM but sometimes I get more of a shine than a polish. I just note that when I describe the Jade I use. The usual way is to define the better grade and polishing Jades as fine grained Jade or if very top grade I refer to it as "gem" or "jewelry" grade Jade with gem and jewelry meaning the same thing.
Here are a few photos of a beautiful but very hard to polish Jade from here in Washington State. I refer to it as having a lot of "texture, difficult to polish and taking more of a shine than a polish.
