'heart' abalone pearl is where the muscle of the abalone was directly attached to the shell. It is very fine grained and kind of 'bubbly' looking, rather than broadly pearly. I normally did not use the heart paua abalone (Haliotis iris) for much, it was kind of waste from the regular paua abalone pearl. I had a customer a while back who, after looking through my pearl types, wanted a heart paua abalone pearl rosette in a Port Orford cedar top. Well, that rosette came out really well, so ...
I decided to do one again, this time in a redwood top. It really makes an interesting rosette.
Since the last one came out so well, I decided to do its sibling in heart abalone also, but this time it is in pink abalone ((Haliotis corrugata) instead of paua abalone.
