In response to Richard's (Scubaman's) question- To make the design, I just cut at a 45 halfway into the blank (to about the center) and then backed out. They were cut with a bandsaw but each cut needed to be widened a bit. After each cut I glued in the ivory, cut off the excess and then cut the next side, glued, trimmed etc until I got all the way around. A coworker just pointed out that a better way to do it would be to cut from both sides, making a v-cut, then glue in the inlay and glue it back together. I could then do a v cut on the other side(s) and glue them up. That way you could use whatever thickness you want for inlays and it would always match up. Maybe I'll try some more some time with varying angles, it could be really cool.
