Clutches for Less

Pearls come in many shapes and sizes whether they are real or not, and it’s not always easy to tell the difference between the genuine article or a fake. Even amongst genuine pearls there are many different classes of both natural and cultured varieties, all with their own different properties and all valued very differently as pearl jewellery. You don’t want to be fooled when buying pearls, so here are some methods you can use to tell the difference between a genuine pearl and a fake:

The Tooth Test
Many people say that by rubbing a pearl against your teeth you can tell whether it’s real or fake by the feel of its surface. Genuine pearls usually have a rougher, more irregular texture in contrast to imitation pearls which are usually very smooth or even glassy. In reality this test is far from foolproof, as fakes are often made to appear completely genuine and some real pearls can sometimes be smooth, particularly if the surface has been dyed.

The Sun Test
A slightly more reliable method is to take the pearls out in the sun and take a close look at the appearance of the lustre, or shine, that you see on the surface. Apart from extremely unusual and rare specimens, real pearls hardly ever appear perfectly matched in full daylight and have clear differences in shine, iridescence and colour.

Surface Magnification
Don’t underestimate the power of a magnifying glass – a closeup look at the pearl earrings, necklace or brooch can tell you a lot, and is one of the most effective ways of distinguishing between genuine and fake pearls. The surface of a real pearl is crossed with hundreds of tiny almost invisible crooked lines, giving them an almost scaly look under magnification. It also helps to look closely at the drill holes in the pearl, which are normally as small as possible in a real pearl as larger holes devalue the gem. Real pearls usually have holes drilled from either end, so the hole is much smaller in the middle of the pearl.

Shape
One of the most obvious ways to identify real pearl sets is to look closely at the shape of each pearl and whether or not they are close to being identical – real pearls are hardly ever perfectly round, and it is almost unheard of to find a whole string of pearls of exactly the same size, shape and weight. Real pearls that are regular in this way are extremely expensive, and if not they are probably fake.

X-Ray
The best way to be absolutely positive of a pearl’s authenticiety is to have it verified and certified by a qualified gemologist. For a fee they will be able to x-ray the pearls, showing any variations in density and discovering how the pearl was first formed and what the nucleus was. You need to be pretty certain that the pearl is real before paying the price for a validation, but some fakes can be very convincing and it’s the only way to really be 100% sure without damaging the pearl.

An oyster of record breaking size in the UK has been discovered in a market in Plymouth. The giant shellfish, which has been dubbed ‘Shelly’, measures 7” across and weighs 3lb. It’s currently residing in the local aquarium, where it is on public display and proving to be quite the tourist attraction.

Unfortunately for fashionistas who are loving the current revival of pearl jewellery though, there’s no chance of a giant hidden gem inside the shell, because Shelly is the wrong type of oyster. It’s an especially large example of the edible oyster, the only species that live in the English Channel. Edible oysters do produce ‘pearls’ but they are of no value, those pearls that are used to make jewellery come from different species of oyster.

The valuable pearls used to make pearl earrings, necklaces, bracelets and other jewellery are found in Pteriidae or feathered oysters, which nowadays are farmed on large pearl farms across the world, mainly in China. Pearls are formed inside the shell of an oyster when a grain of sand or other irritant finds its way in and the oyster protects itself by building up layers of a secretion known as nacre to cushion it with a smooth surface. Natural pearls are a lot more highly valued than the cultured variety as they are much rarer and hard to find.

People have been wearing pearls throughout history, it’s tradition for brides to wear pearls and they have constantly featured in the wardrobes of the rich and glamorous for generations. They are a sign of purity and love, and large pearls are a way of publicly displaying wealth and class. The introduction of cultured pearls to the jewellery market has made them more widely available in recent years, and the popular vintage fashion revival along with a number of high profile celebrities publicly displaying their love for pearl sets and other classic jewellery means pearls are as desirable as ever. The most recent celebrity flashing her pearls on the fashion pages is America’s first lady Michelle Obama, who is becoming a star in her own right for her individual style and ‘imaginative’ choice of accessories combining pearls, brooches and waisted belts.
