If you don't know a lot about pearls (and most people don't, including your average high street jeweller) this page will help you avoid some of common pitfalls.
Although there's no universal standard for grading pearls most reputable sellers adopt the A, AA, AAA system. Tahitian pearls may be graded using the A to AAA system or an A to D system.
Unfortunately even this unofficial standard can be abused if a seller uses a grade like AAA to describe pearls which do not meet the generally accepted quality criteria for that grade.
Sometimes, definitions like AAAA or AAA+ are used to imply superior pearls. When you see this, discount one A or the plus sign to compare products.
The term 'gem quality' is a description for a pearl without fault. Such pearls are more commonly used in earrings, pendants and rings than in necklaces or bracelets.
and the winner is...
we run a little competition to find the most over-graded necklace and this will take some beating! It featured on a tv shopping channel, described as Grade AAAAA. It's actually not bad value for the money but five As ? Click on the image for a closer look.
Investment Grade: Pearls are a wonderful natural gem but they are not an investment and will not appreciate in value.
Japanese Akoya Pearls: This description has been abandoned by most pearl professionals. Japan is the world's largest importer of Chinese Akoya pearls where they are processed and re-exported. A 'Japanese Akoya Pearl Necklace' will almost certainly contain a high proportion of Chinese Akoya pearls - you can't tell the difference.
Whether a pearl originated from the coastal waters of China or Japan doesn't matter. All pearls are made of the same compound (calcium carbonate) and are judged by their size, shape, lustre, surface quality and colour - not their birthplace. If someone tries to obtain a premium price for 'japanese pearls' don't ask where the pearls come from. Ask where they were farmed.
Some pearls from the Phillipines may be described as 'baby South Sea pearls'. Usually, they are imported freshwater pearls.
The Japanese Pearl Exporters Association Inspection Tag (the blue tag) is sometimes used to denote quality.
The JPEA is a voluntary organisation which examines pearls from any country and passes or fails them on the basis that they meet a minimum market standard. A blue tag doesn't mean the pearls were cultured in Japan, are top grade, or any better than pearls without a tag.
Think of it in the same way as a car MOT. A certificate says only that the vehicle passes a minimum roadworthiness standard. It doesn't mean it's a good car or that it won't break down next week.
Black pearls are rarely jet black but blue, green, grey, aubergine, peacock and more. Green is the predominant colour. Naturally coloured black pearls come from the pearl farms of French Polynesia (Tahitian pearls) as well as Indonesia and the Phillipines.
Except for freaks, there are no natural black freshwater or Akoya pearls though these may be dyed or irradiated to simulate black pearls. This isn't a problem - it doesn't harm the pearls - unless they are passed off as natural or Tahitian.
Genuine Tahitian pearls are expensive and subject to stringent quality control inspections by the government. Some pearls may by-pass this scrutiny so it's sensible to buy from a trusted source.
Think of a white marble covered with a single coat of clear nail varnish. It'll look good when new - round, shiny and flawless. After a few months or so there'll be chips in the varnish and soon whole areas will flake or peel off. That's pretty much what can happen when the nacre covering a bead nucleated pearl is too thin.
Thin nacre can be a disappointment with seawater pearls (it's not usually a problem with Tahitian or South Sea pearls and freshwater pearls are solid nacre). Commercial pressure may make farms harvest pearls early, with nacre thickness less than 0.2mm.
It's tricky to spot thin nacre on delivery. If it's cracked or peeling around the drill holes it's not an good sign.
Ok - we're biased, but many 'UK' pearl sellers you find on the first page of Google and other search engines are based in the USA or China. Just because a seller has a domain name like pearlsite.co.uk doesn't mean it has more than an accomodation address here, if that.
Does the price include import taxes? If not, you will have to pay the courier an extra 25-30% in vat, duty and handling charges. Beware suppliers sending items labelled 'gift'. Customs are onto this and take a dim view!
If you are unhappy with your purchase how will you return it? One-off courier charges are expensive and insurance is minimal. You can, in theory, reclaim vat and duty on returned goods but the procedures are cumbersome.

They're cultured pearls and they look the same on screen but one of these 8mm pairs costs 4 times the other.
"Retail £1350. Our price £270"
Unless you buy jewellery in Knightsbridge you are not going to save 80% or more by shopping for pearls on-line.
From a specialist internet pearl retailer you'll probably pay about a half to two thirds the price of an equivalent pearl product from a department store or high street jeweller. Most pearl specialists buy their pearls direct from pearl farms or processors.
It's not easy taking decent 'photos of pearls but real pearls don't look like glass beads...
imitation pearlsGo by many names like simulated, organic, faux and semi-cultured. Good imitations are made from beads of glass, ceramic or shell and coated with a varnish of laquer and ground fish scales to mimic the pearl surface.
Well made imitations can be quite hard to spot. One way is the 'tooth test'.Gently rub the pearl under the cutting edge of your top front teeth. Don't bite it.
A real pearl should feel slightly gritty due to it's crystaline structure. An imitation pearl will feel smooth. This is not an infallible test.
take heart!Most pearl sellers on the internet are honest retailers. You know enough now to avoid the rogues.
