Hosting over 130 exhibitors and welcoming roughly 3,000 show guests from all over the world, the Intergem is the leading international, specialist show for gemstones. This is where jewelry manufacturers, goldsmiths and designers stock up with new materials for sparkling dreamlike jewels and seek information on new trends and gemstone discoveries.


Intergem 2006 will take place in ldar-Oberstein from September 29 to October 2, 2006. The world of gemstones is at home in Idar-Oberstein. If new gemstone deposits are discovered anywhere in the world, for example the recent new discovery of Paraiba tourmaline, it is fair to assume that ldar-Oberstein will be in on it. It is this close link to the leading firms that makes this trade show the most important meeting place for purchasers from all over the world. Visitors here will find a unique range of rough stones and set jewelry from over 50 countries in the world. Small producers also exhibit at the Intergem, and the variety on offer benefits as a result. In addition, ldar- Oberstein represents a cluster of know how for processing colored gemstones and diamonds that is unique in the world. Together with innovative ideas, this established expertise continually provides impulses for new cuts.

This is where Germany’s gemological competence is at home. The leading gemstone and diamond testing laboratories and numerous industry institutions such as the Office of the International Colored Gemstone Association (ICA) or the Polytechnic College for Gemstone and Jewelry Design all have their headquarters in ldar-Oberstein. The Intergem reaps the rewards of the booming demand for colored gemstones. Fashion designers around the globe are increasingly presenting gaudy, joyful creations on the catwalks. And that calls for matching jewelry to show its colors. Red tourmaline, Paraiba tourmaline and aquamarine are important topics this year due to the current fashion colors. In addition, there is a tendency to use larger stones in jewelry Intergem offers a large selection, especially in this bracket. Simply due to their value, the stones require significant specialist competence in processing. This is why large stones are mainly cut in ldar-Oberstein and not in the Far East.

Gemstones as a Reflection of Time

“Moonstones and fire opals are in fashion, and will remain so,” believes the gem expert Constantin Wild. Wild, from ldar-Oberstein, is the fourth generation to head W. Constantin Wild & Co., established in 1847. He considers the two stones to be a reflection of our time, with all of the associated contradictions: “That includes the return to traditional values, together with harmony with nature and a tendency towards individuality and exclusivity. Classical styles are back in demand at the beginning of the 21st century.” According to Wild, all of these requirements “are satisfied by the fire opal, with its varying appearance and different cuts, as well as the moonstone.”

Fire opals and moonstones by Constantin Wild

The Mayas and Aztecs were early appreciators of the precious “Quetzalitzlipyollitli”, the “bird of paradise stone”, as they called the fire opal. Transparent, non-opalizing stones can be beveled to traditional, sparkling jewels. In addition to their fiery color, the high-quality opalizing stones also display the typical range of colors. Their expressive character is well-suited to use in designer jewelry – cut to a variety of forms or polished and left in their natural shapes. The caressing, oval, cabochons in contrast are considered the classical shape for precious opals, as they bring their powerful luminescence to bear the best.

Extravagant and classic, sophisticated, sensual and esoteric – the reputation of the moonstone is also one of contradictions. The return to conservative values such as family and etiquette has brought the blue moonstone back into the spotlight. The stone was very popular around a hundred years ago, in the Art Nouveau period. Its discrete color and blue shimmer make the moonstone ideal for jewelry with a discretely feminine radiance.

The more intensive, larger and transparent, the more valuable this gemstone is. Especially fine blue moonstones display a “three dimensional” depth of color that becomes more apparent with movement. Examples such as this are very rare. Constantin Wild works almost exclusively with high-quality moonstones from Sri Lanka and from the newly-discovered deposits in Tanzania. Only those are shimmering with such an extravagantly intensive blue on an almost transparent background. The fact that finest quality moonstones have become scarce in recent years has led to a sharp increase in prices.

Moonstones are always cut in the classical cabochon forms. Only experienced cutters are able to create adularescence in the stones, that is to enhance the sensual shimmer to its full effect. The decisive factor in this is the optimal height of the stone and the axes of the crystal, which must point directly toward the zenith of the stone in order to achieve the mysterious light effect.

The Entire Spectrum of Keshi Cultured Pearls

As a highlight of the 2006/2007 season Perlen Yukie offers the complete range of Keshi cultured pearls, from Akoya and fresh water to South Sea and Tahiti Keshi cultured pearls. The Keshi 6 la Carte motto of the Merzig-based pearl specialist focuses primarily on the large selection of Akoya Keshi cultured pearls in a variety of colors, from gray and crème to beige, in baroque shapes. The pearls are offered for sale in sizes ranging from 1.5 to six millimeters, with metallic luster. All products on offer are rough goods, i.e. strands for the Akoya Keshi cultured pearls and lots for the South Sea and Tahiti Keshi cultured pearls in a range of different shapes and colors. A specialty of Perlen Yukie is South Sea Keshi cultured pearls in sizes from two to five millimeters. Shapes vary from round pearls to buttons, oval and drop-shaped cultured pearls in the colors silver-gray to gold.

A further highlight is the Tahiti Keshi cultured pearls offered as long, baroque, drop-shaped pearls in sizes up to 20 millimeters. Perlen Yukie is using new ideas to address the topic of seed pearls, the Suna Keshis, familiar from the traditional necklaces of 50 to 100 rows. In its fine necklaces, the company combines seed pearls with black diamonds or gemstones in three or five rows. With their unique creations, the designers aim to rejuvenate the image of these particular cultured pearls. The jewels offer an understatement with rarities, discrete but nonetheless eye-catching and distinctive. Perlen Yukie hopes to use this to herald a new era for seed pearls.

The jewelry collection with Akoya Keshi cultured pearls has been expanded to include new open pearl scarves. Here too, the combination with various gemstones stands out. The jewelry collection is intended for pearl lovers with an eye for the unusual, who are not satisfied with standard pieces. “We want to move away from the traditional image of cultured pearls, toward modern, younger jewelry collections,” explains the Managing Director of Perlen Yukie, Boris Dillenburger.

The Magical Colors of Fall

Colored gemstones contain the whole range of nature’s hues. Jewelry designers can use them much in the style of a painter, capturing the seasons, moods and light. The warm orange to glowing red tones of fall are expressed with mandarin garnet, Madeira and Palmeira citrines and red tourmalines. The renowned Idar-Oberstein gemstone cutters Groh + Ripp have numerous brilliant individual stones, together with calibrated goods from this spectrum of colors in their range. The company has been an expert partner for all gemstone processors since 1953. 38 employees ensure that every customer requirement is met: beginning with the fine, individual hand work and moving on to series production using machines.

Gemstones as World of Experience

“A staged experience, imagination visualized by handcrafted art,” was how Hermann Spaan, professor at the University of Applied Sciences in Trier, described the cuts of Tom Munsteiner at the opening of a studio exhibition. The works of this renowned gemstone designer from Stipshausen have already been awarded numerous international prizes. Master gemstone cutter Tom Munsteiner is also a gemologist. He sculpts gemstones freehand. He is fascinated by the matter of crystals, most of them are more than 230 million years old. Tom Munsteiner likes to work with polished and matt surfaces. “It gives optical depth and means a reduction in the design,” he explains. “I also experiment with geometric forms, I place a great emphasis on the total reflection of light.” The stones that he works resemble sculptures. The cuts follow the natural crystal structures of each stone, thus serving to underscore its individual personality. As a consequence, each gemstone receives the cut best suited to it, as the 9.84 ct. Paraiba tourmaline in the current collection illustrates (right side in the middle).

Strong Comeback of the Classics

Karl Faller is recognized today by jewelers and manufacturers in this specialized area as the incarnation of perfect craftsmanship of the most genuine colored stones. The enterprise is characterized on the basis of tradition, creativity, art and expertise. The rubies by the company Karl Faller, vibrantly alive and full of energy, illuminate the vital color of red in different shades and special nuances. The most desirable one is the so-called “pigeon blood red” shade, a deep and pure red with a touch of blue. Magical powers have been attributed to ruby’s intensity of color as a symbol of power, courage and dignity, with its everlasting fire that ultimately is never spent.

Blue, the color of the life source of water, is the most popular version of the sapphire. Ranging from a tender sky blue, the highly appreciated radiant “cornflower blue” and the preciously deep Kashmir blue, the sapphire impresses us due to its strong independent life of its own. This vitality, as well as its enormous radiance, make the sapphire the most desirable “stone for the day”. Along with the colorless diamond, labeled as purely white, the red ruby, and the green emerald, the sapphire rounds up the quartet of jewels. Diverse and lively as our floral world – the emerald appears in its fascinating green. Its green color is so incomparable in nature that this color hue is labeled independently as “emerald green”. Even in ancient times, the stone was perceived as the symbol for value and beauty.

Its intensive green color and transparency stand for finest quality. The emerald belongs to the beryl group, like the aquamarine and the beryl. It is regarded as the most precious among them. Transparency occurs only in its finest quality appearances. Especially today, the fine qualities of these three most desirable jewels determine the fashion trend of major jewelers and are in the focus of worldwide consumer interest once more.
