What is a Cultured Pearl?
Natural pearls are so rare to find in nature that most pearls sold today are cultured. To create a cultured pearl, a tiny bead is implanted into the oyster and gradually over time the oyster coats the bead in many layers of natural minerals and proteins. These layers are referred to as nacre (Nay-Ker.) It is the nacre that gives pearls their beautiful lustre and colour.
The general colour of a pearl is also called the body colour. Typical pearl colours are white, cream, yellow, pink, silver, or black. A pearl can also have a hint of secondary colour, or overtone, which is seen when light reflects off the pearl surface. For example, a pearl strand may appear white, but when examined more closely, a pink may become apparent.
Pearls produce an intense, deep shine called lustre This effect is created when light reflects off the many layers of tiny calcium carbonate crystals that compose the pearl. This substance is called nacre. When selecting a pearl, consider that the larger the pearl, the more nacre it has, so it will also exhibit even more lustre. Compare a 5mm Freshwater cultured pearl with a 10mm South Sea cultured pearl and the difference in the amount of nacre is obvious. The difference in lustre is as clearly visible as the difference in the pearl sizes
Shapes that are not spherical or even symmetrical are considered lower quality. Akoya, Tahitian, and South Sea pearls found in jewellery have a tendency to be the roundest, while Freshwater pearls can be oval or slightly off-round
The size of the pearl greatly depends on the type of pearl. Freshwater pearls range in size from about 3.0–7.0mm, Akoya pearls range from about 6.0–8.5mm, and South Sea and Tahitian pearls can reach sizes as large as 13mm.
When cared for properly, pearls can last a lifetime. The best way to care for pearls is to wear them often as the body’s natural oils keep pearls lustrous. However, it’s important to keep them away from household chemicals including perfume, make-up and hairspray. Chemicals found in these common products can dull the lustre of your pearls. It is recommended that you put your pearls on last when getting ready and make them the first thing you take off when you come home. Before putting your pearls away, wipe them with a soft cloth and store them separate from other jewellery.
Pearls are exceptionally cohesive and shock-resistant, but may be scratched by contact with sharp objects or other gemstones. To prevent tangles and scratches, fasten clasps and pins, then lay each item out separately in your jewellery box. When carrying pearl jewellery, use a protective pouch. Leaving pearl jewellery in a security box for long periods may cause pearls to dehydrate, so enjoy them frequently. There is a saying that “pearls want to be worn,” and it is true!
WEARING YOUR PEARLS
Be careful not to dip pearl strands in water or wear them while bathing, as water can weaken the silk thread. It’s also best to avoid direct sunlight or high temperatures such as in a sauna. If pearls come into contact with substances such as vinegar, fruit juices or detergents, immediately wipe clean with a soft cloth. Following these simple guidelines should preserve your pearls for generations.
cultured pearl necklaces are strung with the finest silk thread for both strength and beauty. However, if that string stretches or loosens, it may break suddenly. Even if you don’t wear your pearls often, we recommend that you have your pearls restrung every 2 years.
