6 ways to determine pearl quality

Pearl Quality

Pearls come in a variety of shapes, sizes and colours. These factors are important to determine pearl gemstone quality, here are 6 examples used by professionals in the precious gemstone industry:

Non round, round and near-round pearls are measured by diameter in millimeters. One millimeter is 1/10 of a centimeter. Larger baroque pearls are measured by Depth and Diameter. No matter the shape, a larger pearl is always more valuable.


2. Shape


There are three categories of pearl shape, spherical, symmetrical, and asymmetrical. Baroque Pearls come in six shapes: near-round, button, drop, oval, semi-baroque, and baroque.




3. Colour


Pearls colour is determined by three components: The overall colour of the pearl, overtone-the translucent colours that shine over the surface of the pearl and orient-the iridescent glow below the pearls surface.


4. Luster


Luster is the light reflected from a pearls surface. Luster is what gives the pearl its irresistible beauty. Pearls with excellent luster have bright surface reflections displaying many different colours.





5. Surface


All Natural and Cultured Pearls have blemishes and marks on the surface. Surface characteristics are judged by their size, quantity and location. If surface characteristics are many or severe it can affect the value of the pearl. Clean, lightly blemished Pearls fetch the highest prices.
