Good questions. With all the different pearl colours and types on the market, it can be difficult to know simply what you’re wanting at. For those interested by buying pearls, or for gem fanatics who wish to learn extra, listed below are answers to some of the most commonly requested questions about pearls.  

Are All Tahitian Pearls Black?
Not solely are Tahitian cultured pearls not solely black, they’re additionally not grown in Tahiti. Referred to as “black” because of their unique dark colours, Tahitian cultured pearls can also be grey, blue, green and brown. And so they’re grown in the lagoons of small islands which might be a part of a group often known as French Polynesia. Tahiti, the biggest island, serves as the group’s center of commerce, and not as a pearl growing mecca.   

Tahitian pearls are cultivated for about two years in Pinctada margaritifera cumingi, a big mollusk native to French Polynesia. One of the ways this unique oyster differs from other species is its inside shell colour, which is dark. This so-referred to as “black lipped” oyster additionally has black mantle edges—the “lips” that give this animal its descriptive name.

Today, the most sought-after Tahitian cultured pearls are dark inexperienced-gray to blue grey with rosé or purple overtones. Pearl colours are decided by several components, together with variations within the host oyster, colour variation of the implanted donor mussel tissue, the quantity and thickness of nacre layers, and variations in rising surroundings resembling temperature and water quality. Tahitians are most often variations of grey, black, green and blue, but different colours exist.

At a mean size of 8mm-14mm, Tahitian cultured pearls—particularly these specimens that are gem-quality and spherical—are very expensive. In keeping with the most recent info from the Gemological Institute of America, up to 40 percent of implanted black-lipped oysters produce a gem-quality cultured pearl, but only about 5 % of the pearls they produce are round. And only 1-2 p.c of your complete crop will end in round cultured pearls of the best quality. No surprise a Tahitian pearl strand is so pricey! If you wish to put on Tahitian cultured pearls, one way to take action without breaking the financial institution is to decide on a pendant-model necklace with a single pearl, pearl stud earrings, a single pearl ring, or baroque (non-symmetrical) pearls. These designs are each bit as unique and much more affordable than a matched strand.

What’s the difference between a cultured pearl and a pure pearl?
Natural pearls are shaped when an irritant, reminiscent of a parasite, makes its means right into a pearl-producing animal comparable to an oyster or mollusk. To protect itself, the animal coats the irritant in nacre—a combination of natural substances that also makes up what we name mother-of pearl. Over time, the layers of nacre build up across the intruder and finally kind the natural gem everyone knows as the pearl.

Cultured pearls are formed in the same way as natural pearls, with one massive difference: they get their start not by chance, however intentionally, when man intervenes with nature. To supply cultured pearls, a talented technician, called a nucleator, induces the pearl-growing course of by surgically placing an irritant—a mom-of-pearl bead and a bit of mantle tissue, often—into a mollusk. The animal is then positioned back into the water and monitored, cleaned, etc. till the pearl is able to be harvested.

The Chinese language have been culturing freshwater blister pearls (pearls that grow underneath the mantle on the within of the animal’s shell) for the reason that 13th century, but Kokichi Mikimoto, a Japanese man, is credited with developing modern pearl culturing techniques. By the early Nineteen Twenties, Mikimoto was selling his cultured pearls worldwide.

Natural pearls can be very beautiful, but resulting from overfishing, air pollution and different elements, they are a rare discover indeed.  Thus, nearly all pearls bought at this time are cultured pearls. There are two most important types: freshwater and saltwater. South Sea cultured pearls, Tahitian cultured pearls and akoya cultured pearls are all kinds of saltwater pearls. Cultured pearls of all types can be present in jewelry stores worldwide.

Are saltwater pearls higher than freshwater pearls?
It is determined by who you ask, but many pearl consultants as we speak agree that freshwater cultured pearls can rival the fantastic thing about their saltwater cousins. Resulting from enhancements in culturing methods, freshwater pearl farmers are producing lovely, spherical, lustrous pearls which can be an unlimited improvement over the wrinkled, rice-krispie-shaped gems that typified the freshwater pearl crop of the not-so-distant past.

Produced primarily in China, freshwater pearls are sometimes nucleated, or implanted, with mantle tissue solely (rather than a mom-of-pearl bead). As a result of they do not comprise a starter bead, tissue-nucleated freshwater pearls are 100% nacre. This provides them a lovely luster and a sturdy surface that gained’t simply flake or peel to reveal the interior bead. Against this, pearls that are bead-nucleated and harvested too quickly usually have only a thin coating of nacre that can flake or peel. This can be a main drawback: Unlike many different gem stones, pearls can’t be polished back to perfection.  

Freshwater cultured pearls are available in many stunning pure pastel colors together with cream, white, yellow, orange, pink and lavender. (Universally flattering lavender pearls are very talked-about proper now.) White pearls are bleached to enhance their pure shine. Black freshwater cultured pearls are handled with dye or heat to produce their inky color.

Total, freshwater pearls are more plentiful than different pearl sorts, thus they are generally extra affordable.

Are South Sea pearls really golden?
Yes. Pearls produced in the aptly named “gold-lipped” oyster (P. maxima) generally is a attractive creamy yellow, referred to as “golden” in the trade. (The silver-lipped variety of P. maxima produces beautiful silver or white pearls.) Grown in the South Seas—which stretch from the southern coast of Southeast Asia to the northern coast of Australia—these pearls are grown in one of the largest oysters utilized in pearl culturing. As a result of they can accept a bigger bead and secrete nacre quicker than their smaller counterparts, these huge oysters produce large pearls of outstanding luster and beauty. South Sea pearls’ thick coating of nacre provides the gems an exquisite luster, or glow, that appears to return from deep throughout the pearl. The nice and cozy waters, considerable meals provide and low air pollution ranges of the South Seas also help these oysters produce stunning cultured pearls.

Although Australia produces 60% of the world’s South Sea cultured pearls, Indonesian farmers work extra with the gold-lipped oyster, and thus produce more golden pearls. The silver-lipped selection produces equally beautiful pearls that are available white to silver and sometimes have rosé, blue or inexperienced overtones. Apart from giving them a lightweight wash, pearl farmers do not deal with South Sea pearls after harvest.
