    Accompanied by a certificate from The Gem and Jewellery Institute of Thailand stating that the pearl is a natural non-nacreous pearl. Certificate number 10.08.30.12065, dated 3rd September 2010.

    Non-nacreous pearls are extremely rare. It is particularly unusual to find one of near-round shape and only the finest examples show the flame-like structure that can be seen in this pearl.

    Non-nacreous pearls are formed within a mollusc that does not produce mother-of-pearl. The pearls are built up of concentric layers of columnar or fibrous aragonite crystals in a parallel pattern. The flame-like structure is produced when the upper layers of aragonite crystals are arranged in two directions, which overlap each other. The highest quality have a porcelain-like appearance with a silky or velvety sheen.
