Edison Pearls

Edison pearls are simply one brand of bead nucleated freshwater pearls from China. Bead nuked pearls started to appear five years ago and can be divided into two main categories, depending on the quality of their nacre: either smooth or rippled. From this you can split the smooth into Edison (a brand from the pioneer of this type of pearl), Ming, (the second brand, not allied to any particular wholesaler) and generic bead nucleated pearls.

(Just to remind, until a few years ago freshwater pearls were usually all nacre, with pearl growth triggered by the insertion of just a sliver of mantle tissue into a host shell. It was only sea water pearls (South Sea, Tahitian, Akoya and a few freshwaters such as coin pearls) which had a bead template nucleus as well as that sliver of mantle tissue)

Edison is the brand name given to a range of large bead nucleated freshwater pearls from one leading Chinese supplier. One strand of these pearls achieved £1/2m at auction. The pearls come from a Hyriopsis hybrid between Hyriopsis cumingi and Hyriopsis schlegeli.

The Ming pearl name tends to be applied to the better quality of generic bead nucleated pearls. It is more of a description of quality than a brand. (Edison is a brand, belonging to one pearl farmer/wholesaler. They tend to be the most expensive and can be the finest quality available in the world)

In general these new bead nuked pearls can be any quality from superb to – like any pearls – terrible quality, with pitted, ringed, thin and lumpy nacre and washed out colour with chalky lustre. That’s probably what you’ll get if you bought from an unknown seller on any auction site. Quality (and, of course, price) runs up to metallic lustred 15mm perfectly round. flawlessly smooth surfaced pearls

Mabe

A blister pearl which has been hollowed out and filled with a substance and backing. Mabe pearls are often made into earrings A mabe is a hemispherically shaped pearl which is grown against the inside of the oyster’s shell, rather than within its tissue Blister pearls are worked by cutting the pearl out of the shell with a circle-bit drill. The nucleus is then removed and replaced with a resin. The back of the pearl is capped with a piece of mother-of-pearl to complete the mabe pearl.

Maeshori

This is a Japanese term which means before (mae) treatment (shori). It encompasses treatments used on all akoya, freshwater and some South Sea pearls. Maeshori treatments vary from factory to factory. The processes tighten the nacre and pull moisture out to enhance the lustre. This has a side effect of tending to make the nacre more brittle, so that freshwater, pearls that have been overtreated will turn chalky very quickly. Maeshori processing on South Sea pearls is very common in Japan. It makes the pearls whiter, brighter, and more saleable. One basic maeshori process is tumbling in chips of walnut shell which cleans and burnishes. This is considered so standard that it is not normally a declared treatment

Majorica or Majorcan pearl

A high-quality fake pearl manufactured in Spain by Majorica, S.A. These nuclei are dipped in high quality essence d’orient ( varnish made up of the scales from bleak, shad, herring and salmon. 2,000 fish make one litre of essence, which is an organic substance similar to uric acid.)

Mantle tissue

The special tissue inside certain molluscs which secretes nacre Metallic Lustre A pearl has a metallic lustre when the lustre is so shiny that it resembles polished metal. Metallic lustre is not a criterion in the usual grading system

Ming

What are Ming pearls? They are usually the better quality generic bead nucleated freshwater pearls, but some people throw that description at any quality of such pearls. As a quality description it is really pretty meaningless. Calling a pearl a Ming pearl does not of itself guarantee any sort of quality.(see bead nucleation and Edison for further info)

Momme

A momme is unit of weight, used for silk or pearls, and you will still sometimes see pearl prices quoted as per momme – with the price given against quality. One momme is 3.75 grams and one Kan is 1000 momme

What are Ming Pearls?

Ming pearls are simply one brand of bead nucleated freshwater pearls from China. Bead nuked pearls started to appear four years ago and can be divided into two main categories, depending on the quality of their nacre: either smooth or rippled. From this you can split the smooth into Edison (a brand from the pioneer of this type of pearl), Ming, (the second brand, not allied to any particular wholesaler) and generic bead nucleated pearls.

(Just to remind even more, until a few years ago freshwater pearls were usually all nacre, with pearl growth triggered by the insertion of just a sliver of mantle tissue into a host shell. It was only sea water pearls (South Sea, Tahitian, Akoya and a few freshwaters such as coin pearls) which had a bead template nucleus as well as that sliver of mantle tissue)

So..what are Ming pearls? They are usually the better quality generic bead nucleated freshwater pearls, but some people throw that description at any quality of such pearls. As a quality description it is really pretty meaningless. Calling a pearl a Ming pearl does not of itself guarantee any sort of quality.

February 5 2016 addendum

Contrary to what was just claimed on QVC Honora do not buy up the entire harvest of Ming pearls. Pearlescence has plenty of Ming pearls in stock and will probably buy many more in three weeks when we go pearl buying in Hong Kong. The Honora claim is simply not true,

Day five.. pearl finding

Leave a Reply

White mirror metallic rounds.

A busy day again, full of pearl finding. I picked up where I left off, working through the wants list of loose single and pairs. It took more than an hour to find ten perfect pairs of AAA white mirror metallic pearls. It is staggering how many variations are possible in what should be a simple task – after all, how much variety can there be? Well the answer, of course, is zillions. For perfect pairs the size, colour, overtone, lustre and mirror size and quality must all match perfectly.

Of course that is perfection. Later in the day Betty Sue King and I were sadly contemplating some big round bead nucleated ‘pairs’ most of which were sort of maybe something like. Betty Sue is a leading American pearl supplier with a lifetime of knowledge and skill in the pearl world. I just sit there learning when she is in the room.

Before that though one of the highlights was a collection of nuggety ice cream coloured 10mmish undrilled mirror metallics. Not sure what I will do with them, but at the moment I’m thinking some pretty and feminine station bracelets with silver chain.

Once I had paid for the pearls at the morning supplier I moved on to a second. Poking around the shelves, I pounced on some big and colourful bead nucleated baroques. Some of them huge -30mm and more. They were bead nukes gone a bit wonky.

Variable in quality, never the less, there were some big colourful baroques for some dramatic earrings. There were two bags of those, and then one bag of pretty rubbish pearls in which was modestly sitting this huge true blue pearl

The pearl is a true blue, not a grey with a blue overtone. It is truly blue

The wholesale staff member and I both gasped. You can see how how big the pearl is. There are a couple of fairly big flaws but ..oh that colour!

It’s now mine (of course!)

For the last hour I dashed off to the findings supplier and grabbed silver, vermeil and gold clasps, earrings, pendant fittings, rings, enhancers and so on. Oddly the staff wanted to go home, so I left my basket. I’ll select some of the beautiful Italian-made and designed woven silver necklets

Day Two…..Phew……lots of pearls

A great day.Spent the whole day at my favourite supplier and we’ve made some serious inroads into the big ‘wants’ list.Lots of pearls.

9.30 in the morning. I’m already seated at the big table, and there are some huge dark ripples spread out before me. Life is good!

In the end I selected a beautiful AAA metallic strand of bead nucleated pearls, a strand of really big soft gold white ripples and a strand of huge dark ripples.

Next were bead nucleated singles. various sizes and I’ve got a collection of the most stunning colours with the most intensely metallic lustre you could ever want

Stunning drops

Then I was shown some of the latest harvest of Ming bead nucleated pearls. Phew. Up to 17mm, pretty much clean with only faint blemishing and metallic lustre and rich colour. I couldn’t decide which to select (all three?) so asked Twitter. Within a few minutes my mobile was throwing out replies! Each strand had votes. Watch this space to see what I decided.

Moving right along, How do 13mm and 14mm white metallic drops sound to you?

Finally I was given the first showing of some totally new pearls. They are small, 5mm to about 9mm, but with intense colours and mirror metallic lustre. Anyone have any idea what these little beauties are

Mystery new pearls

I resisted the impulse to immediately buy every one and found nine pairs – mostly smaller sizes, for earrings and some singles which will be set onto rings. No-one yet has got what they are!

Being dutiful I tried to move on to black drops but when I spread them out I glanced at the clock…nearly 6pm! No wonder I was all pearled out for the day!

Nacre depth on bead nucleated freshwater pearls

Leave a Reply

There’s been a lot of debate recently about the nacre depth on bead nucleated freshwater pearls, along with concerns about the materials being used as the nucleus.

Rather fortuitously while we were making up some necklaces recently and enlarging the drill holes so the silk can be doubled back and hidden two pearls split neatly in half.

One was a white 12.6mm Ming – metallic lustre with rainbow overtones and the other was a prototype small Edison white round of 9.5mm and rippled creamier nacre (If you don’t know the two pearl brand names don’t worry, just ignore).

Nacre depth is a real problem with saltwater Akoya pearls. Some pearls spend such a short time being grown that you can see the bead through the nacre (this is known as blinking because the pearls appear to blink when rolled back and forth). Thin nacre is one of the reasons why we have not carried an extensive stock of Akoya pearls up to now – although having found a couple of suppliers who guarantee decent nacre we will be stocking them more in future)

Tahitian and South Sea pearls are always grown on an inserted bead

But bead nucleation has exploded onto freshwater pearls in just the last few years. With large grower to wholesaler Grace pearl leading the way Chinese pearl farmers are producing huge round pearls from a schegeli/cumingii hybrid in the most amazing range of colours, some pastel and some deep, such as deep purples, as well as rippled surfaced pearls, nicknamed ripple pearls, with shimmering play of colours and often an effect like gold leaf has been added in patches.

Classic ripple pearls – pink, lavender, blues, and the gorgeous gold leaf overlay effect

Anyway, here is the result of the two broken pearls…

You can clearly see the beads and the layer of nacre. In the smaller pearl the nacre is just 0.6mm thick (minimum depth for a Tahitian pearl is 0.8mm over 80% of the pearl surface) so that would be a fail, while the larger pearl has a happy 1.23mm of nacre. Plenty.

Bead nucleated pearls and tissue nucleated pearls.

Leave a Reply

There are two basic types of farmed pearls: bead nucleated and tissue nucleated. (The other main type classification is between cultured or farmed and natural or wild pearls)

Nucleation is the process which starts off the growth of a cultured or farmed pearl. It involves inserting something into a nacre-producing mollusc to trigger production of a pearl. This nucleus can be either just a tiny sliver of mantle tissue on its own or a sliver of mantle tissue plus a bead or other shaped foundation. In either case a nacre secreting pearl sac grows and a pearl is made within that sac.

Bead nucleated pearls include all tahitian and south sea pearls, akoya pearls and many modern big freshwater pearls (brands Edison and Ming) as well as fancy shapes such as coins or hearts.

Tissue nucleated pearls are mostly all freshwater pearls which are therefore all nacre, solid pearl. no bead inside. (Chinese and Biwa freshwaterpearls)

Keishi pearls are an exception. They are the pearls formed inside a usually pre-existing pearl sac from which a pearl has been removed (think of how a balloon looks when the air seeps out over time and you get the idea of a keishi pearl.

Mantle tissue is used because that is the area of tissue which specifically secretes nacre. It’s usually there to make the mollusc’s shell but will produce nacre wherever it is – a talent utilised by the pearl farmer.

Placement of the nucleus varies as well. Beads are placed in the sex organ – the gonad – of the mollusc and only one per mollusc. (You might think that this would stop the mollusc from wanting to reproduce but there is some research which indicates it make them more not less active!)

Tissue nucleated pearl grafts can be many to a mollusc and are placed in the mantle.

The new big thing (last three or so years only) in pearls are the big freshwater bead nucleated pearls from China. These are branded as Edison pearls or Ming pearls or are described as ripple pearls. They are big – up to 17mm, round or symmetrically baroque (because of the bead inside), have a lustre ranging from metallic to gloriously satiny, and a smooth to convoluted or rippled. They come in a range of natural colours from white to pink, purple, peach, gold, with greens and blues. (you can see our ripple pearls here and we have smooth surfaced Edison and generic bead nucleated pearls throughout the freshwater section ..here is one beautiful example of a bead nucleated Edison pearl necklace
