Take your time with the finer grits as well, and keep looking at the ring at different angles to reveal any blemishes or missed spots. There are a couple of options available to finish. If you have acces to a drill press or lathe, and can afix the ring to it securly, putting a small amount of super glue on the spinning ring will give a nice polish and some added strength. Alternatively, you can use a few (maybe 2 or 3) coats of fast-dry poly. This seems to give the best polish, and can be done with about 30 minutes between coats.
You can see in the pictures how the finer detail of the grain pattern begins to emerge as you move to finer grits. The poly coating increases the contrast between variations in color and gives a nice lustre.
Thanks for taking a look at my project, and I hope you enjoy. A ring like this makes for an interesting and durable gift, and it'll be sure to please whoever you make it for.
