By far, the hardest to obtain pearls on Earth are those of the marine "baler" snail, found in the Indo-Pacific region: round, smooth and sometimes quite large, I recently held one in my hand that was the size of a large gumball and nearly dropped it when the price of $50,000 was quoted to me. The colors and flame structure are similar to those of the conch pearl.
