Have you ever wondered how pearls form within an oyster and emerge from their shell in a perfectly round shape? Is this something they do on a regular basis? Does the form of pearls vary from one to another? They're not at all! Although the round pearl form is one of the most common, it is also one of the rarest pearl shapes accessible. So, they are the most precious (and hence, the most costly) items. Near-round, off-round, button-shaped drop-shaped, Baroque, and circular are just a few of the various pearl forms available. Hawaiian Pearl jewellery is available from Koko Val Hawaii.
