I looked up sphene and it's about a 5-5.5 on the Mohs scale... A pearl is a 2-2.5
I'm not trying to talk you out of it but just be careful and cautious with it.

Mohs only measures scratching, and yes a pearl will scratch easier than a sphene. But a sphene (and some other stones with relatively high Mohs) will break or cleave when struck or dropped. Even a sapphire, second only to a diamond on the Mohs scale, will break when dropped.

Noted- but having scratches all over a pearl take away from the luster and overall look of the piece.. So while it may not snap in two, the deep scratches that will and can happen are inevitable if not babied and worn infrequently. It's not even the same as gouging a stone- pearls cannot have their scratches polished out.
But anyway.. I don't think this really has anything to do with sphenes breaking though.. So moot point.
