However, it is not true when valuating pearls of different varieties. As shown in the image below, you can easily see the difference in pearl sizes when you compare the size of the Tahitian oyster shell against that of the akoya pearl-bearing oyster.
Now you can see why natural pearls are potentially more valuable than cultured pearls. This is because the occurrence of natural pearls is much rarer than cultured pearls. Almost all real pearls you see today are cultured. One thing to bear in mind – some jewellery intentionally mismatches pearls to achieve a specific look. What matters in this case is the visual harmony of the design rather than the uniformity mentioned above. The Value of Conch Pearls and Melo Pearls In general, there’re 7 factors that affect the pearl value: shape, size, colour, lustre, surface quality, nacre quality and matching. Like the 4Cs of diamond valuation, the pearl’s 7 value factors are created by the Gemological Institute of America (GIA) to standardise pearl grading systems. They represent the main components of a pearl’s characteristics and beauty in a more balanced and comprehensive manner.
Natural Pearls vs. Cultured Pearls
When other value factors are equal, the second most valuable shape is near-round, and then followed next in value by other symmetrical shapes like oval, button, drop and baroque. How Pearl Size Impacts Its Value? Natural pearl colour is an important factor that affects the value of a pearl. It has three components: bodycolour, overtone, and orient. Akoya Pearls are the classic, round white pearls that most people are familiar with. They’re mainly cultivated in Japan and China in a saltwater oyster species called Pinctada fucata martensii. Natural Akoya pearls grown in this species are extremely rare. Bodycolour is the overall dominant colour of a pearl. Overtone, the secondary colour, is the translucent colour that lies on top of the bodycolour. It’s usually present over the entire pearl surface or a large part of it. Orient appears when there’s more than one translucent colour or overtone over the bodycolour. It’s visible in a much smaller area on the pearl surface and can come in a form of iridescent rainbow colours. Pearls that have no blemishes at all or contain very tiny surface characteristics that are not visible without using special equipment are said to have Clean Surface. Depending on the degree of their blemishes, pearls can be Lightly Spotted, Moderately Spotted and Heavily Spotted. How Matching Impacts Price Of Pearls?
Despite their huge price difference, both cultured and natural pearls are real pearls. They are grown from pearl-bearing oysters in either saltwater or freshwater. The pearl formation process is exactly the same for both natural and cultured pearls. So how can you tell if the pearls you own are natural or cultured? Unfortunately, you won’t be able to spot the difference without proper gemological and laboratory tests. Testing methods such as X-rays, energy-dispersive X-ray fluorescence, laser light, and Raman spectrometry will help separate natural from cultured pearls. What Affects The Value Of A Pearl? If you’re an avid follower of luxury fashion and jewellery, you probably have noticed some of the spectacular record-breaking prices set by natural pearls in recent auctions.Freshwater Pearls are the most widely available pearls seen in jewellery today. Hence, they’re the most affordable types of pearls in the market. Freshwater pearls are commonly grown inside the Hyriopsis cumingii mollusc in rivers, lakes and ponds in China, and their production has also started to grow in Southeast Asia in recent years. When other value factors are the same, the higher the lustre, the more valuable the pearl is. The lustre of some fine quality pearls can be so intense that it is almost metallic. In this guide we’re going to show you everything you need to ascertain what your pearls are worth. The Basic Rule To Buying Pearls
