Lustre is best described as the shine that gives a pearl their beauty and is an important factor in identifying quality.
Lustre also refers to the way the Pearl surface reflects light, and to its inner glow – how it refracts light from the layers of nacre within. Pearls with low lustre appear chalky, yellow or dull – Whereas the lustre of good quality pearls is sharp and bright.
Pearls develop into various shapes. Round pearls are the rarest and command the highest prices.
The term ’round’ does not mean spherical like a marble. Pearls should not be obviously oval or flattened to the naked eye. Baroque pearls are not symmetrical in shape, and can be lustrous and appealing, and will typically cost less than round pearls.
Sea Pearls are created in the ocean by a wild oyster, while Freshwater Pearls are created by using freshwater mussels in lakes, rivers and ponds.
Nature almost always leaves its mark, it is extremely rare to find a perfect pearl. The cleaner the surface of the pearl, the more valuable it becomes.
Unacceptable faults may include cracks or holes in the surface or thin and flaking nacre. The highest quality pearls have a sharp, mirror-like reflection. Blemishes are natures way of letting us know a Pearl is genuine.
Pearl size is measured in terms of its diameter. The size of the Pearl is important because larger pearls are harder to find. As the pearl size increases, its range also raises high. The difference in size could raise the price by 200 per cent.
