I remember getting this parcel of beautiful "Easter Egg" colored gems. I had it for about 6 years, and would cut one or two stones a year. One Sunday afternoon, I decided I would just cut the whole parcel. I rubbed the lot of them, and they are ready to finish.
I have a great variety of opal rubs, and if you are a beginning cutter -- trying to finish a guaranteed gem, these could be the way to go for you.
