It’s worth noting that different pearl type has its own unique characteristics and benchmarks. Therefore, you cannot simply take each value factor and use it to assess two different types of pearls.

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. In 2010, China overtook Japan in akoya pearl production. [46] Japan has all but ceased its production of akoya pearls smaller than 8mm. [46] Japan maintains its status as a pearl processing center, however, and imports the majority of Chinese akoya pearl production. These pearls are then processed (often simply matched and sorted), relabeled as product of Japan, and exported. [47] But hold on – notice we use the word “potentially”. That’s right! Not all natural pearls are worth more than cultured pearls. Why? Because the beauty and value of a pearl relies on many other factors, such as size, shape, colour, lustre and nacre quality.

Cultured pearls can be distinguished from natural pearls by X-ray examination. [13] Nucleated cultured pearls are often 'preformed' as they tend to follow the shape of the implanted shell bead nucleus. After a bead is inserted into the oyster, it secretes a few layers of nacre around the bead; the resulting cultured pearl can then be harvested in as few as twelve to eighteen months.

Saltwater pearls grow within pearl oysters, family Pteriidae, which live in oceans. Saltwater pearl oysters are usually cultivated in protected lagoons or volcanic atolls.Clam with huge pearl.

Present day natural pearling is confined mostly to seas off Bahrain. Australia also has one of the world's last remaining fleets of pearl diving ships. Australian pearl divers dive for south sea pearl oysters to be used in the cultured south sea pearl industry. The catch of pearl oysters is similar to the numbers of oysters taken during the natural pearl days. Hence significant numbers of natural pearls are still found in the Australian Indian Ocean waters from wild oysters. X-ray examination is required to positively verify natural pearls found today. The nucleus bead in a beaded cultured pearl is generally a polished sphere made from freshwater mussel shell. Along with a small piece of mantle tissue from another mollusk (donor shell) to serve as a catalyst for the pearl sac, it is surgically implanted into the gonad (reproductive organ) of a saltwater mollusk. In freshwater perliculture, only the piece of tissue is used in most cases, and is inserted into the fleshy mantle of the host mussel. South Sea and Tahitian pearl oysters, also known as Pinctada maxima and Pinctada margaritifera, which survive the subsequent surgery to remove the finished pearl, are often implanted with a new, larger beads as part of the same procedure and then returned to the water for another 2–3 years of growth. Natural (or wild) pearls, formed without human intervention, are very rare. Many hundreds of pearl oysters or mussels must be gathered and opened, and thus killed, to find even one wild pearl; for many centuries, this was the only way pearls were obtained, and why pearls fetched such extraordinary prices in the past. Cultured pearls are formed in pearl farms, using human intervention as well as natural processes.

A few species produce pearls that can be of interest as gemstones. These species include the bailer shell Melo, the giant clam Tridacna, various scallop species, Pen shells Pinna, and the Haliotis iris species of abalone. Pearls of abalone, or paua, are mabe pearls, or blister pearls, unique to New Zealand waters and are commonly referred to as 'blue pearls'. They are admired for their incredible luster and naturally bright vibrant colors that are often compared to opal. Another example is the conch pearl (sometimes referred to simply as the 'pink pearl'), which is found very rarely growing between the mantle and the shell of the queen conch or pink conch, Strombus gigas, a large sea snail or marine gastropod from the Caribbean Sea. These pearls, which are often pink in color, are a by-product of the conch fishing industry, and the best of them display a shimmering optical effect related to chatoyance known as 'flame structure'. Bycroft, Michael (2019). Gems in the Early Modern World: Materials, Knowledge and Global Trade, 1450–1800. Switzerland: Palgrave Macmillan. p.124. ISBN 9783319963792. Pearl lustre is the intensity and sharpness of the light reflected from a pearl’s surface. In other words, it shows how bright and shiny a pearl is. Pearl lustre is considered the most important quality attribute of all the 7 pearl value factors. Fine quality pearls will always display high lustre with bright and sharp reflections.R.

She is wearing a multi-strand choker and a rope of pearls The second largest pearl known was found in the Philippines in 1934 and is known as the Pearl of Lao Tzu. It is a naturally occurring, non-nacreous, calcareous concretion (pearl) from a giant clam. Because it did not grow in a pearl oyster it is not pearly; instead the surface is glossy like porcelain. Other pearls from giant clams are known to exist, but this is a particularly large one weighing 14lb (6.4kg). The metaphor of a pearl appears in the longer Hymn of the Pearl, a poem respected for its high literary quality, and use of layered theological metaphor, found within one of the texts of Gnosticism.

Mamangkey, Noldy (2009), Improving the quality of pearls from Pinctada maxima, PhD thesis: James Cook University After WWII, new south sea pearl projects were commenced in the early 1950s at Kuri Bay and Port Essington in Australia, and Burma. Japanese companies were involved in all projects using technicians from the original Mitsubishi South Sea pre-war projects. Kuri Bay is now the location of one of the largest and most well-known pearl farms owned by Paspaley, the biggest producer of South Sea pearls in the world.
