Gemstone collection from Indian Ocean sets off on second world tour

The return of the gemstone collection of my grandfather Wilhelm Constantin Wild to Idar-Oberstein last year was an occurrence I found especially moving. Do you remember? In September a Pakistani fisherman found the leather coffer dating from the mid-20th century in a bag together with some other gemstones in the North Indian Ocean near Karachi. What moved me was not only his decision to send the collection back to Germany – but also the touching gesture he made in replacing the missing tiger’s eye with a pearl.

Exclusive exhibit at international trade fairs 2018

The story of the honest finder attracted plenty of attention in the media. Having been on show in Idar-Oberstein for some months, the collection is now setting off again on a world tour: visitors to the international fairs in Tucson, Hong Kong, Basel and Idar-Oberstein will be able to admire the valuable specimen book on location. The exemplary collection shows the fascinating facets of coloured gemstones – from ruby, sapphire and emerald to agate, lapis lazuli and malachite.

Christmas 2017 – Why you should give yourself a present too

Self-gifting is a trend that is becoming more and more popular, both in the United States and in Germany. But giving oneself a present – isn’t that a bit crazy? Not at all, say the motivation researchers. People who reward themselves with a gift are giving their soul a wellness break. Nothing motivates people more than recognition and esteem. But it’s also important to have a positive image of oneself and acknowledge one’s own achievements. So even if we Germans do usually find it rather difficult: give yourself a pat on the back. Regularly!

Moments of happiness, but with enduring value

Women who wish to use Christmas as a long-awaited opportunity to self-gift will be on the safe side with an investment in exclusive gemstones. Coloured gemstones, available in almost limitless variety, become sparkling memories – of a special occasion or project. The positive side effect of self-gifting is that a woman can be a hundred per cent certain of getting exactly what she wants. The colour of the stone can be selected to suit her wardrobe, her attitude to life or the colour of her eyes. There’s no limit to individualism here.

That fact that the quantities of stones such as tanzanite, mandarin garnet, tsavorite or tourmaline mined are far smaller than that of diamonds is certainly no disadvantage when it comes to investment. Apart from that, gemstones are not subject to wealth tax or inflation.

However, it’s important when making a purchase to pay attention to the quality of the stones. The interplay of colour, cut, clarity, carat weight and origin is so complex that professional advice is called for. “If self-gifting is to be more than just a well earned moment of happiness, interested parties should definitely enquire at a jeweller’s about the colourful diversity of gemstones”, comments Constantin Wild, who is in business as a gemstone merchant in Idar-Oberstein himself, representing the fourth generation of his family in that line.

A purple sapphire brings out the shine

In memory of the American singer Prince, the Pantone Color Institute has developed the new colour ‘Love Symbol #2’. With this lush purple tone, the institute posthumously honours the artist who achieved one of his greatest hits with ‘Purple Rain’ in 1984. Since then, violet has been inseparably associated with the musician, glamourous and passionate as he was. “The color purple was synonymous with who Prince was and will always be”, said Troy Carter, entertainment adviser to Prince’ estate.

Fans of this unforgettable musician can now rejoice: the gemstone purple sapphire brings out the shine in this new Pantone hue in an impressive way. Having said that, anyone wishing to acquire one is going to have to dig fairly deep into his pocket, as this stone – just like the pop legend of whom it reminds us – is a genuine rarity.

Sapphires are regarded as exquisite gemstones with many colour variants from sky blue to deep dark blue. The purple sapphire is a particularly rare variety. Many people have never even heard of this stone. Each purple sapphire is unique and much coveted, not only among collectors.

Gemstone collection from Indian Ocean back in Idar-Oberstein

It’s like something out of a fairy tale: at the end of September a Pakistani fisherman pulled a collection of 29 gemstones, some 80 years old, out of the Indian Ocean. Thanks to the imprint of a company stamp he was able to identify Wilhelm Constantin Wild of Idar-Oberstein as the original owner. The fisherman decided that the gemstone collection, being part of family history, should make its way back to Germany. He also thought it would be a nice token of friendship between Muslims and Germans. Being an upright man, he waived his right to a finder’s reward. In a particularly touching gesture, he said he would like to fill the empty compartment with some pearls, making the family a present of them in lieu of the tiger’s eye which was now missing from the collection.

“At first, it wasn’t at all clear how or when my grandfather’s collection would be able to find its way back to Idar-Oberstein”, says Constantin Wild. But with the aid of an international logistics company, the collection, which has a high sentimental value for him, soon set out on the journey home. This very week, the entrepreneur received the extraordinary package from Pakistan.

Once it has been examined to verify its genuineness, he will be handing the collection over on loan to the German Gemstone Museum. “Later, of course, the find will be given a place of honour in my treasure chamber”, says Constantin Wild.

Details still to be clarified

It will now be possible to examine exactly how old the collection is. Early assumptions suggest that it was probably put together between the First and Second World Wars, since Idar and Oberstein did not actually amalgamate until 1933. At any rate, the stamp with the impression ‘Idar-Oberstein’ originates from the time after the amalgamation. The high-quality workmanship which can be seen in the photos is a clue indicating that this was one of the earlier issues of this kind of collection, for in later years these were mass-produced cheaply, finding their way out into many parts of the world.

Exhibition at the German Gemstone Museum

Anyone wishing to inspect the gemstone collection him or herself will be able to admire it very soon indeed at the German Gemstone Museum in Idar-Oberstein. It will be on view there as ‘object of the month’ until the end of November.

It was clear to Constantin Wild that the warm-heartedness and sincerity of the finder ought to be rewarded. He intends to transfer a finder’s reward of 1000 dollars to the Pakistani fisherman as a down payment on a new fishing-boat, in the hope of improving the life of this honest man and his family.

Five exciting days with Pomellato

How can you put any kind of topping on an unconventional style when extravagance has been at the core of a brand for 50 years? This was the task facing Pomellato’s Creative Director Vincenco Castaldo when he began searching for an idea for the Pomellato Jubilee Collection. He found what he was looking for in the versatile world of coloured gemstones: with 50 really unusual stones, Pomellato will be celebrating the fiftieth anniversary of the birth of the company this year, and with it, the beauty of Nature. As his partner in this lavish project, Vincenco Castaldo chose Constantin Wild of Idar-Oberstein, because in a unique way, we as a gemstone manufacturer full of tradition offer the whole spectrum of the fascination of gemstones, from the raw stone to final production, under a single roof.

Together, the Creative Director, his two assistants Marina De Ponti and Enrica Castelli and myself went down into my raw stone cellar in Idar-Oberstein and set off on an exciting journey of discovery. Kilo by kilo we turned over the raw stones with our hands, aiming to discover the hidden beauty of Nature and set it in the context of an exceptional design.

We were looking for gemstones that had a story to tell. That way, later on, an item of jewellery doesn’t just fulfil a decorative purpose; it‘s also convincing because of its own thoroughly personal statement. Alongside the correct mineralogical designations like zoisite, ruby, aquamarine and dendritic agate, imaginative names like “Secret Garden”, “Foggy Morning” and “White Cliffs of Dover” help to express the soul of each stone.

We also invested a good deal of effort in the selection of pavé stones designed for optimum correspondence with the colours of the principal stone. Since at Constantin Wild we can offer the combination of carrying both unusual coloured gemstones and pavé stones in our range, a combination which is very rare anywhere in the world, we were able to fulfil many of the jewellery designers’ wishes right there and then.

The Pomellato Ritratto Jubilee Collection is not a hark-back to the traditional, but a courageous step toward a forward-looking design. As an exclusive, the ‘making of’ was accompanied by Vogue and Le Figaro. We were glad to receive their editresses as guests at Constantin Wild.

My family’s antique gemstone collection was found in Indian Ocean! Stay tuned!

When I received a mail on Friday 22 September, I could hardly believe it: In the Indian Ocean, not far off the coast of Pakistan at Karachi, a fisherman made an unexpected find: a collection of 29 valuable gemstones, wrapped up in a little leather book!

And guess what, the origin of the collection was soon determined: My hometown Idar-Oberstein, also known as the most important gemstone centre worldwide. Or to be more precise, the stones belonged to my grandfather, the late Wilhelm Constantin Wild, founder of our family company!

Aquamarine shines out in Fall 2017

‘Marina’ and ‘Bluebell’ are among the blue tones in the current Pantone Fashion Color Report for autumn / winter 2017. They fit in perfectly with the colour spectrum of the aquamarine, which, on account of its sparkling lustre in the colours of the sea, is regarded as the “world’s favourite stone”. For the first time, the report by Pantone identifies two colour ranges for the autumn, oriented toward the New York and London Fashion Weeks. Whilst New York chose a bold, radiant blue in ‘Marina’, London made a somewhat more cautious choice in the delicate ‘Bluebell’.

Then as now: the force of Nature

The world of gemstones is in a continuous process of modernisation, but Constantin Wild still puts his trust in hydropower for the processing of his precious gemstones today.

Water is the origin of everything. Especially as it relates to the success story of Idar-Oberstein. For when large agate deposits were found in the Hunsrück in the 15th century, the power of the water in the Idar stream was the only thing that enabled the big grinding wheels to be set in motion so that the raw stones, still grey and matt as they were, could be transformed into sparkling treasures. More and more cutting shops rapidly emerged – and with them, a flourishing industry.

More than just red and blue: fancy sapphires

Rubies and sapphires are amongst the world’s most precious gemstones. Their fiery reds and radiant blues are unmistakable. Less well known are the facts that both these stones are members of the corundum family, and that this family has much more to offer than just red and blue.

The corundum family, in fact, has everything you could want in a valuable gemstone: gorgeous colours, great brilliance, and an excellent hardness of 9 on the Mohs scale, putting it right behind the diamond – our hardest natural mineral – and that means it has excellent wearing properties. Its refraction is unusually high too, as evidenced by the wonderful brilliance of perfectly cut specimens. Experienced cutters know that the colour looks markedly more intense when the stone is viewed from one angle than it does when viewed from another.

Greenery summer 2017: peridot

After they had led a rather shadowy existence, the reputation of peridots gradually began to change: in the high mountains of Pakistan, at an altitude of over 4000 metres, some very fine, brilliant gold-green crystals were discovered. Today, the peridot is among the most coveted coloured gemstones worldwide. Its seductive, lush green hues and clarity have made it a strong competitor of the tourmaline and the emerald. The peridot is one of the very few gemstones which come in one colour only. This stone displays the most beautiful green tones of the summer: its range includes olive shades, the famous gold-green of the stones from Pakistan, a clear yellow green, a light lime green and the bluish green typical of stones from Burma. Very small but beautiful yellow-green stones come from China. And the best thing about this gemstone is that its colour will flatter the complexion of any woman! However, these fantastic stones do have one major disadvantage: all of them are very rare. Fortunately, I have a few remarkable peridots in my treasure chamber.

Sparkling greetings,
Constantin Wild
