Calcareous Concretions are produced by many shellfish. This is what most people find in edible oysters; They are not true pearls and are often found in a rainbow of colors such as pink, pale green, cream, white, or blue. Unfortunately, they often are not durable with color fading quickly and eventually deteriorating.​
