Tears of Mermaids, The Secret Story Of Pearls

by Richard W. Wise, G.G.

Layout 1First let me say I was a bit put-off by Mr. Bloom’s prose style.  He is without a doubt an elegant writer, but the glib-gonzo style, which is ok in a short piece, rapidly gets under the skin when stretched out to book length.

Mr. Bloom is a journalist and though journalists are not expected to necessarily be experts on the subjects the write about, they do have a responsibility to thoroughly research the topic and get it right.  There are times when Bloom does, but there are   times when he does not.

His first and most egregious error occurs in his introduction.  “Pearl pricing”, he says, “is totally subjective …The same strand can go for three thousand dollars or thirty thousand dollars.”  Nonsense!  Oh yes, there is a fool born every minute, but the fact is that pearls trade in a fairly orderly market.  So, absent the fool, no such gap between bid and ask prices exists (or the buyer would be soon out of business).  Bloom would have been correct if he had said that there is no universally accepted hierarchical grading nomenclature.  That is to say, one dealer may call the finest pearls “AAA”, while another may simply start with a single “A”.  However  the basic criteria: size, symmetry, surface, luster, orient and overtone are universal and used by all.

The writer’s statements about the people he meets in his travels say a great deal more about Mr. Bloom than they do about his sources.  For example, early in the book he meets a survey group, including the celebrated former National Geographic writer Fred Ward who “seemed too important to have anything to do with me.”  Well, I am familiar with that group and they have one afternoon in which to survey an entire gem show full of pearl dealers.  Could it be that Ward was simply focused on his work? Given the book’s stated objective, one wonders why his Chapter 5, The Rana of Fresno, was included at all.  Bloom takes such obvious pleasure in exposing the foibles, real and imagined, of his sources that, at times, it is difficult to tell if he is truly writing a book about pearls or just an extended gossip column.

Bloom’s comparison between the pearl and cocaine trade is unfortunate,  as are the constant inferences that the pearl trade, and pearl dealers in general, are really quite sleazy.  Bloom spends a page and a half justifying the cocaine comparison, finally admitting that “the biggest difference is that the possession of pearls is legal.”  Cocaine is sold by neighborhood dealers and pearls by local jewelers, hey, no difference there!  He might also have mentioned that unlike cocaine, pearls are not reduced in purity at every step along the distribution pipeline, and do not destroy the life of the purchaser– but that would have ruined the riff.

The above issues aside, there is much of value in Bloom’s book.  Few have the opportunity to spend so much time trying to understand this old and arcane industry.  Bloom’s first chapter, covering the history of pearls from the time of Columbus, is well researched and provocative.  Interesting as well is his chapter on life as a deckhand on a Pearl boat off the Australian coast, though his attempt to capture the Australian argot is ludicrous and his contempt for the working sailors palpable.  Yeah Stephen, having been a deckie, I kin tell yuz dat is ezakly the way sailors are “supposed to talk.”

His chapter on pearl trading in Hong Kong is excellent as is his description of diving off the Jewelmer pearl farm. A looming environmental catastrophe in the Philippines and his last two chapters about his visit to the island of Cubagua (where it all began) are thoughtful and poignant.  Had he spent more words discussing real issues of this sort and less time lampooning the hard working people who made his book possible (I am one of those local jewelers), I would have enjoyed it a good deal more.

Chinese Pearls; The Re-emergence of Quality!

Its been a long, long road.  The first known account of pearl culturing in China dates to 1086 (Donkin 1998).  In modern times, China has been producing commercial quantities of freshwater pearls since the 1970s.

From the early 70s the best of the small production coming from a small number of Chinese farms were sold to the Japanese.  The pearls were almost impossible to tell from the expensive Lake Biwa production and once they reached Tokyo, they were miraculously converted to Japanese pearls and sold as such.  By 1978, fully 60% of Japanese “Biwa” exports consisted of  pearls made in China (Strack 2006).

By the mid-80s a few Chinese freshwater pearls leaked out of the pipeline.  I recall buying from one dealer in Tucson, small 5-7mm single button  and egg shaped pastel colored pearls with the metallic luster for which they have since become famous.    By the late 80s pioneers like Fuji Voll of Pacific Pearls was bringing in 7-9mm high luster, smooth buttons which could be easily matched and sold at very big markups.  The problem of dealers is that more kept coming, they kept getting bigger and better and prices kept falling.

Then in the late 80s culminating in 1994 large numbers of round 9-14mm suddenly appeared in the U. S. market.  Prices were all over the place.  I saw some exceptional 9-10mm almost rounds for a couple of thousand dollars as well as similar stands for over $4,000.   James Peach showed some amazing singles up to 14mm and exhibited one strand of completely round metallic natural color pastel pearls with an asking price of $85,000.  Suddenly everyone became a pearl dealer.  Then poof, these high quality round pearls were gone.

The high quality rounds disappeared and left many a newly minted pearl dealer high and dry.   What happened.  I have heard several stories.  According to Strack, more farms were added in 1994 which led to falling prices in 1995, so farmers simply left their shells in the water unharvested for two years resulting in a spike of high quality large rounds.  Another story told to me by a dealer:  it takes two years to produce a 10mm+ nucleated South sea pearl and five years to produce a non-nucleated 10mm+ Chinese round and the Chinese figured they couldn’t compete.   Whatever the reason, high quality rounds disappeared and all that was left at the high end were off-rounds the market dubbed “potatoes.”

Bigger  Rounds Are Back:

A couple of weeks ago, Jeremy Shepherd of Pearl Paradise sent me two strands of 9-9.5 mm Chinese metallic multicolor and these pearls were truly eight way rollers.

The beads were round, the skin smooth and the luster metallic.  These are qualities reminiscent of the mid-90s.  According to Shepherd there are indeed larger sizes in production but quality drops off rapidly above 10mm and prices begin to increase geometrically for finer pearls above that size.

Total Chinese pearl production peaked in 2007 at 1,600 tons and have been declining every year since.  Production in 2010 is estimated at 1,000 tons approximately the same level  as 2004.  Seems like the Chinese are working towards higher quality. Continue reading

Choosing The Perfect Pearl

Ten, make that eleven tips to help you choose the perfect pearl


by Richard W. Wise, G.G.

1. There are two types of pearl, natural and cultured. In today’s market just about every pearl you see will be cultured meaning that the hand of man had something to do with the creation of the pearl. (pictured above a necklace of mixed South Seas white and golden pearls)

2. We are experiencing a pearl Renaissance. There are more types of pearls on the market today than ever before. Twenty years ago the Japanese Akoya stood virtually alone. Today you can choose from: Freshwater pearls, South Seas white, Tahitian black and South Seas golden pearls.

3. What’s the best buy in pearls? Probably the Chinese Freshwater, (pictured left 8.5mm round natural color Chinese f/w pearls) There are two ways to create a cultured pearl, bead nucleation and tissue activation. Pearls that are bead nucleated have a large bead made from shell and thin covering of nacre depending upon how long they are left in the mollusk. Chinese freshwater pearls are tissue activated, have no bead and are pure pearl. They are available in natural pastel or white and in their finest qualities have some of the characteristics of natural pearls. Be careful, over 90% of Chinese freshwater pearls are of marginal quality. The best will stand toe to toe with any pearl in the world and can be purchased for a third of the price. To help you in selection, pay careful attention to the following guidelines:

4. Pearls are often treated, usually to change or improve the color. Pearls are routinely dyed and irradiated. Natural colors are, by far, the most beautiful. Japanese Akoya, the pearl that is seen most in the market is routinely bleached white then dyed to give it a pinkish overtone. If the color looks too good to be true it probably isn’t.

5. A fine pearl has what experts call “life”. This is a combination of high surface luster and overtone and occasionally orient. All pearls exhibit luster, those with thick nacre will usually show excellent luster. Observe the pearl(s) on a white background under a light bulb, if you can distinctly see the outline of the bulb the pearl has high luster.

6. Some pearls exhibit an ephemeral misty glow that seems to hover over the surface of the pearl. This is called overtone. Not all pearls exhibit overtone, for example, it is very rare in South Sea white pearls. If present in white pearls, the overtone is usually pink, in Tahitian black pearls, green, red or blue or some combination (pictured right). Orient is rare in round and semi-round cultured pearls. Orient may be defined as a rainbow affect that changes as the pearl is rotated in the light. Orient is chromatic, meaning it will show all the colors of the spectrum whereas overtone is normally monochromatic exhibiting one color such as pink. A ball bearing can have wonderful luster but the addition of overtone or orient adds dimensionality and life to the pearl (pictured right: orient in Chinese f/w baroque pearls. Below (right) distinct orient in a pearl shell).

7. To judge if all the pearls in a strand are round, hold the strand taught between your hands and rotate the strand between your fingers. In a round strand you should see no movement but if some of the pearls jump about like the cams on a cam shaft, the strand is not completely round.

8. Odd shaped pearls, called baroques, are not to be disparaged. If they have good luster, no scratches or cracks they have a younger hipper look than the more expensive rounds. You can wear them with jeans and they are available at a substantially lower price.

9. Pearls have flaws just like other gem. These may be dimples, scratches or cracks. A dimple here or there should not be of much concern however, one that looks like it has a bad case of chicken pox should be highly discounted. A pearl with a deep scratch or crack is unacceptable.

10. Beware lower priced Japanese Akoya pearl, if your grandmother has a strand of white round pearls they are likely Akoya. These are formed by placing a shell bead in the oyster. In the last few years, Japanese farmers have dramatically reduced the time the pearl is allowed to develop in the shell resulting in pearls that are little more than nacre plated beads with less than ¼ millimeter of pearl essence or nacre over the shell bead. These pearls are often bleached then dyed pink to simulate overtone. These pearls lack luster and are prone to flaking.

11. Pearls come in many nuances of color but color is not the issue. It doesn’t matter how good the pearls look in the jeweler’s case, the real question is how the pearl looks against your (the wearers) skin. Pearls come alive when placed against skin of an appropriate color and texture. This is a characteristic I dubbed simpatico in my book: Secrets Of The Gem Trade, The Connoisseur’s Guide To Precious Gemstones. Don’t prejudge, test the simpatico of each strand by placing it against the skin on the inside of the wrist. The skin in this area is the same color and texture as the skin around the ears and neck. The result may surprise you.
