history of South Sea pearl cultivation By David-John Turner
South Sea pearls had been sourced from the silver-lipped and gold-lipped, 'Pinctada Maxima' oyster of Australia's waters since the dawn of time. For thousands of years, Aboriginal fishermen had dove for these naturally occurring South Sea pearl oysters using their meat, shell and pearls for trade and tribute. Unfortunately, as with all things precious, by the late 1800s the modern world had all but depleted Australia's natural South Sea pearl resource. However, off the north-eastern coast of Australia, a method was being unearthed that would not only revitalize Australia's South Sea pearl industry but pearl production the world-over.
The British marine biologist, William Saville-Kent, served two posts as Australia's Commissioner of Fisheries, one in Queensland and one in Western Australia. In 1891, while on Queensland's Thursday Island, Saville-Kent experimented with grafting one oyster's mantle tissue, inserted with a nucleus of shell, into another oyster's mantle. This caused the formation of a pearl sack which produced nacre covering the nucleus to form a spherical pearl.
Pioneering the technique, William Saville-Kent, acting as scientist and Commissioner freely passed the method onto other interested parties working in Australia's north-eastern pearl industry. At that time, Australia's pearl industry comprised of tens of thousands of people, including Aboriginal Australians, Europeans, Chinese, Malaysian and Japanese; amongst who were Tatsuhei Mise and Tokishi Nishikawa.
It should be noted that many cultivated pearl industry texts on the web wrongly credit the Japanese entrepreneurs Tatsuhei Mise, Tokishi Nishikawa and Mikimoto Kokichi, with the invention of the nucleated cultivation technique. To this day, William Saville-Kent is not officially recognized as the father of this procedure and the resulting cultivated round pearl.
In 1907, both Mise and Nishikawa applied for the patent of Saville-Kent's method, but realizing that they were now competing against each other they unified to patent and name it the 'Mise-Nishikawa' method. That same year, quite probably in search of sponsorship, Nishikawa wrote to Mikimoto Kokichi telling him of his discovery; "...I have found the cause of Japanese pearl formation, i.e. the reason why and how the pearl is produced in the tissue of the oyster..." (G.F Kunz: 'The Book of the Pearl' 1908).
In 1916, Mikimoto and Nishikawa joined forces and went into large scale production using Saville-Kent's original technique, using it to cultivate the Akoya 'Pinctada Fucata' pearl oyster. The implementation of this ground-breaking procedure marked the beginnings of a boom in Japan's pearl industry. By 1935 Japan was producing more than 10,000,000 cultured pearls every year.

Belgium Culture
Antwerp has been very prominent in diamond cutting for five hundred years—the first written mention of diamond cutting is in Antwerp in 1550. Located in the Flemish section of the country, Antwerp is on the northwest coast of Belgium. In the very early years of European development, Antwerp was over-shadowed by Brugge in terms of international trading, but became the absolute center of Belgian trading when Brugge was struck by the plague.

Wedding Ring
So you’ve got the ring. A dazzling, shiny engagement ring. Your next step: picking out the perfect wedding band to complement that ring. First, get something you like. Consider your lifestyle and taste.
There are ways to simplify your diamond investment, says Anne Pokoski, certified gemologist appraiser at Elleard Heffern Fine Jewelers in St. Louis.
Pokoski says the wedding couple’s shopping experience should be fun, exciting and done with confidence.
TIPS FOR DIAMOND WEDING RING
- Brides today are more interested in wedding bands filled with diamonds than the plain gold or platinum band.
- If your engagement ring is an emerald-cut diamond, which generally has an understated sparkle to it, consider a wedding band with baguettes or side stones to complement the set.
- A princess-cut diamond tends to feature geometric styling. It would be ideal to choose a wedding band also with princess cut diamonds.
- If your engagement ring has a solitaire, pear, oval or marquis-shaped diamond, a round band embellished with diamonds may match best.
TRENDS IN WEDDING RINGS
- The round brilliant stone is still one of the most popular diamond shapes.
- The oval and princess-cut diamonds are relatively newer cuts, popular among younger brides.
- Some brides are showing a strong interest in older cut diamonds such as the Asscher-cut and the Cushion-cut. These styles from a century ago bring back creative looks in platinum.
- You may want to consider a wedding set made with colored stones. This new trend has brides and celebrities choosing some of the hottest colors of diamonds in shades of yellow, pink, brown and purple.
REMEMBER THE 4 C’S
Cut: The set of dimensions and angles of the diamond. Cut is the most important factor of the four C’s, because a properly cut diamond will sparkle at its most brilliant, and it will be the prettiest.
Carat: The weight of the stones.
Clarity: Represents the number, size and location of natural birthmarks within the diamond.
Clarity grades range from flawless to imperfect, with flawless being extremely rare.
Color: Amount of color that can be seen by a diamond grader when the stone is viewed lying upside down in special lighting conditions. Color ranges from D, which is completely colorless, up to Z which has strongly noticeable color. Most high-end quality bridal jewelry today is set with diamonds in the colorless to near colorless range from D to K in color.
Ring BAND CHOICES
- Yellow gold for men and women.
- White gold for men and women.
- Platinum for men and women.
- Titanium for men only.
- Tungsten carbide.
TIPS TO MAKE DIAMOND CUT SHOPPING PLEASANT
- Re search the Internet for diamonds choices.
- Look for jewelers with good reputations. Ask friends and relatives for resources.
- Select a jeweler who is a member of the American Gem Society or the Independent Jewelers Organization.

Black Diamond In Watch
Hublot's new "One Million $ Black Caviar Bang" features hundreds of black diamonds.
"When each element is crafted individually and in coherence with the one right next to it, this is invisible from the outside but creates a vibration of harmony which is visible and gives rise to emotion in those who perceive it," Hublot Chief Executive Officer Jean-Claude Biver said in a media release.
The timepiece is the latest to join the million-dollar watch club, whose exclusive members have included a limited-edition Corum "Golden Bridge" watch, Patek Philippe's "Sky Moon Tourbillon," a multicolored diamond version from Chopard, a Jacob and Co. diamond stunner and a pearl-set timepiece from Robert Wan.
