Become a connoisseur of natural pearls in 10 easy steps: Part 1

Here are some key tips and facts on how to recognise a natural pearl!

Natural pearl vs not natural pearl … that is the question. On the exterior and to the naked eye, there is no obvious difference between a natural pearl and a cultured pearl. The difference arises from the fact that a natural pearl is formed accidentally and without any human intervention, while a cultured pearl is started by the introduction of an irritant by man, after which the process is continued solely by the metabolism of the living mollusc. In both cases the formation of a pearl is the result of the self-preservation reaction of the mollusc.  If it does not get expel the irritant it must cover it in nacre, otherwise it will die.

The chances of finding a seawater natural pearl are 1 in 5000. The term natural pearl implies accidental formation without any human intervention. A natural pearl is caused by the protective reaction of an oyster or mussel to the accidental introduction of a foreign body into its organism. This reaction starts by the mollusc covering the intruder with epithelial cells which will form a pearl sac around the intruder, the pearl sac deposits concentric layers of nacre that surround the offending object and slowly form the pearl, layer by layer. Natural pearls can be formed in seawater or in freshwater.

Make a pearl or … DIE Natural pearls occur when a piece of shell, coral, bone or a large piece of grit hooks into the flesh of the oyster, it breaks the surface of the epithelial cells and carries with it epithelial or nacre producing cells. The oyster tries to expel the intruder but if it is unable to dislodge the irritant, this foreign body will start the formation of a pearl. A grain of sand is hardly ever involved in the production of a natural pearl as the oyster lives in sand and can easily expel it. Elisabeth Strack an eminent pearl specialist of our day discovered another way in which a natural pearl can be formed, refer to the diagram shown, if the epithelial cells covering of the mantle is broken and these crucial nacre making cells travel as a group into the mantle, this in turn will form a pearl sac and a natural pearl will be born.

Pearls 101 – What is a pearl?

Where does a pearl come from ? is a question we are often asked. There are many different types of pearl, some rarer than others, but before we start differentiating between them lets first understand how pearls are formed. Pearls are the product of the act of self-preservation by a mollusc, be it an oyster or a mussel. If the mollusc does not react in this way it will die.

In other words the creation of a pearl is caused by the protective reaction of an oyster or mussel to the accidental or deliberate introduction of a foreign body into its organism. This reaction starts by the mollusc covering the intruder with epithelial cells which will form a pearl sac around the intruder, which in turn deposit concentric layers of nacre that surround the offending object and slowly form the pearl, layer by layer.

 

So …what is nacre ?

Craft Film Final Assembly.00_00_16_02.Still002

Nacre is made up of calcium carbonate in the shape of tiny crystals called Aragonite. Calcium carbonate is also found in chalk, our teeth and various other everyday items. With a pearl the Aragonite crystals are held together with a glue-like protein called Conchiolin. In our teeth which are also made of calcium carbonate;  the protein that holds that Calcium Carbonate of our teeth together is stronger than Conchiolin hence when we are invited to “test” the genuineness of pearls against our teeth it is not only unhygienic but totally undesirable as our teeth will scratch the pearl.

 

What makes nacre?

Pearl Birth

Epithelial cells produce nacre and are therefore essential to pearl formation. They are found in a special tissue called the mantle which is found at the hinge and the edge of the molluscs flesh, as seen in the photograph shown. Nacre grows not only on pearls but also as mother of pearl on the interior of the shell. Nacre layers within the shell of the mollusc act as a protective shield against the outside world, making the mollusc less attractive as food to predators.  The only difference between pearls and mother of pearl is that in a pearl the layers are concentric and in mother of pearl they are flat or straight.

 

Where does a pearl gets its lustre from?

pearl layers

Nacre layers play a vital role in the pearl’s lustre. Nacre layers are very thin, translucent and reflect light, thus creating the pearl’s distinctive lustre. Generally the thicker the nacre with regular, thin and translucent layers, the finer the lustre will be on the pearl. In other words lustre is caused by the reflection of light on the surface of the pearl and the refraction of light as it passes through the layers of nacre. This effect appears to make the pearl glow from within.

WHAT IS YOUR COLOUR ?

COLOUR is both very objective and subjective. Many of us know what colours we suit, but do you know what colours will really give you the va va VOOOM effect, easy choose the pearl colour that best suits your skin tone,  consider if you tan well or not and bear in mind the colour of your eyes.

Bluish-grey pearls will generally suit someone with blue eyes, while a peacock green Tahitian pearl will suit someone with green eyes. Warm cream to gold pearls will suit a complexion that tans easily. Another factor that affects the overall harmony of the face is your lip colour without make up. Hair colour should also be taken into consideration when selecting pearls.

A VERY rough guideline of pearl colours that suit different skin tones is set out below:

Olive toned skin – golden pearls

Dark skin – white or warm cream pearls

Pinkish rosy complexion – rose to cream pearls

Pale skin – rose to white pearls

The best cultured and natural pearls have overtones; this effect makes the pearl very attractive and interesting to the eye of the beholder. Warm cream overtones can bring a softness to the final effect, Bright Pink overtones suit people with Blue or Green eyes. Pearls with peacock overtones can be worn with clothes of any colour, as the pearls themselves will echo any tone. The best way to ascertain which colour is the most appropriate is to try on various tonalities within the colour that you are looking to choose from. For example there are four main tonalities within white pearls. Intrigued?

Coleman Douglas Pearls X Aqua Flor Perfume

Pearl Essence Perfume

‘Dawn and Dusk’ are a revolutionary concept in perfume, the new Coleman Douglas Pearl friendly perfume essences. A novel concept on which our designer, Chrissie Douglas and Sileno Cheloni of AquaFlor in Florence, have worked on for the last three years.

A natural creation: Most perfumes have alcohol which attacks a pearls’ radiance and eventually dulls the pearls and even changes the colour of our skin. Dawn and Dusk essences have a base tone of salt and water, mimicking the natural oils produced by our body and maintaining the pearls moisture whilst adding to its splendor. To prove this point, each phial of pearl essence contains a cultured pearl which as time goes by increases in lustre. Once the essence finishes it can be strung into a necklace exuding a gentle scent for years to come.
Easy handling: The delicate phials fit perfectly into a handbag and their “roll on” feature allows for easy use “on the go”.
Our Pearl Essences have two distinct scents
Dawn evokes a fresh morning sea breeze in French Polynesia. Its base notes are Amber and a musk accord of Ambergris and sea moss. Its head notes are seaweed and pink salt whilst white thyme and wild fennel are Dawn’s heart notes.
Dusk has an essence which builds on Dawn and brings a sultry note with base characteristics of amber and a woody accord of ambergris and bamboo wood. Its heart notes are an aromatic melody of white thyme and African rosemary, with seaweed, pink salt and bergamot as its head notes.
