The colour is the main price factor, however pearls do not have a clearly defined colour. Their colour may vary depending on light factors, the colour of the wearer’s wardrobe or the complexion of the person wearing them.
Pearls that have a white colour often have a soft undertone of pink, lavender, greenish or silver. Pearls that are black may have undertones of green, blue-green, silver or copper, as well as the valuable peacock tones. Golden coloured pearls often have additional tones, like gold, silver, pink, green bronze or champagne.
