This pair of cultivated button pearl ear studs is eye-catching because of their exquisite peacock colour. The pearls are approximately 3-3.5mm in size, complemented by sterling silver posts and scrolls. Peacock pearls are fascinating gems renowned for their distinctive and vivid hues. Let’s delve deeper into these exquisite pearls: Definition and Origin:  – “Peacock” pertains to a particular variety of dark Tahitian pearl. – These pearls feature a body tone that ranges from dark green-grey to blue-grey, with an overtone of aubergine or pink. – The Gemmological Institute of America (GIA) categorizes peacock pearls as Tahitian pearls that exhibit these remarkable colour combinations. Tahitian Pearls and Their Overtones: – Commonly referred to as “black pearls,” Tahitian pearls are seldom purely black. – Their body tones vary from grey, steel, brown, green, purple, to charcoal. – Their distinguishing feature is the presence of overtones on their surfaces. – The peacock overtone, also known as “oil slick,” is the most sought-after. – Pearls with a peacock overtone display a spectrum of iridescent colours—greens, blues, aubergines, and pinks—over a base tone of greyish-green, reminiscent of a peacock’s plumage. Factors Influencing Peacock Overtone: – The pearl’s unique colours arise from various factors: * Water minerals: The aquatic environment influences the pearl’s hue. * Black-lipped oyster: This specific oyster species (Pinctada margaritiferid) produces dark nacre. * Formation process: The thickness of the nacre, trace elements in the water, and light reflection all contribute to the pearl’s final appearance. Natural vs. Dyed Peacock Pearls: – Natural peacock pearls are produced by black-lipped oysters, but many available in the market are artificially coloured. – Black Akoya or freshwater pearls are frequently dyed to mimic the peacock coloration but lack the authentic overtone. – It is crucial to differentiate between natural and dyed pearls to make informed purchases. In conclusion, peacock pearls are not only aesthetically pleasing but also embody a complex interplay of environmental and biological factors that contribute to their unique beauty.
