The next time, you might actually want to get a set of pearl bits.
Instead of being diamond bits (which are ideal for harder stones), a
pearl bit is actually shaped a lot like a “spade” bit… imagine an
inverted chevron shape with a little point in the center of the flat
The key with pearls is to go slow, use water, and use the right kind
of bit. The spades are designed to push the nacre up and out of the
hole as it’s being drilled, which also reduces friction and reduces
your chance of burning up the pearl. Also gives a very smooth-sided
hole on the inside, which doesn’t catch your silk.
I think you’ll like the result…
