Factor Value 5
The cultured pearls are organic, so it’s not surprising that they present characteristics of the surface and can be of very different kinds:
– Abrasions: A series of scratches on the surface of a pearl resulting from damage.
– Prominence: A lump, a bubble or a streak, generally very small in size.
– Spalling: a recess or an opening on the surface of the pearl.
– Split: a crack that reaches the surface or a fracture of the nacre, or a break or fracture in the nucleus.
– Flat Area: a flattened area on the surface of a perladi usually limited to influence the basic form.
– Empty: a zone in which the nacre has not covered the spherical core.
– Recess: a small notch or depression on the surface.
– Scratching: Thin groove or depression on the surface.
– Spot: Zone of nacre lighter, darker or duller than the surrounding area.
– Ripple: a major row or irregular wrinkle on the surface.
Because of the intensity variable that can take on the characteristics of the surface pearls; the Youremailverifier, thanks to pearls description system, divides the different degrees of intensity in 4 levels of classification:
– Clean: Pearls no surface features or presented very slight irregularities.
– Slightly Uneven: Pearls with external characteristics of a minor degree.
– Moderately Uneven: Pearls with higher grade surface characteristics.
– Severely Irregular: Pearls with very obvious surface features.
Being organic products, it is very difficult to find a pearl devoid of surface characteristics, so these will have a very high value. The numerous and serious irregularities, such as chipping or lapses nacre, may pose a threat to the durability of the pearl as they may cause further breakage or peeling over time. If the surface irregularity is smaller and positioned in the vicinity of the hole, where it is less visible, it will have a negligible impact on the appearance of the pearl, consequently on its value.
