The expenses of the jewelery shops differ primarily according to the addressed buyer, but not really by the presented jewelry. There is a chance in the differentiation that needs to be used to make regular customers or new customers aware of their own business!
Put your customers first: Make it clear that you as a goldsmith or jeweler will support the customers in their uniqueness and not treat all customers the same. Brown diamonds offer an extraordinary opportunity for jewelery individuality: Who but professionals already knows brown diamonds, diamonds that do not shine white or bluish because of a plastic deformation of the crystal, but in the color of cognac? These diamonds have some advantages: on the one hand, they are about 80 percent cheaper than the classic diamond, on the other hand, when they set in a necklace, bracelet, earring or ring they provide unusual colorful accents. Customers have been looking for the extraordinary for a long time. Prerequisite: It has to be affordable. Brown diamond jewelery fulfills exactly this wish, has the underestimated advantage that it promises to promote sales while also offering a good profit margin. Brown diamonds have a high degree of uniqueness that wearers with character will appreciate. But customers need to know that there are brown diamonds. Promote brown diamonds, demonstrate to your customers how striking and at the same time how individual jewelery made of brown diamonds is. Goldsmiths can use brown diamonds to open up a niche for themselves and their customers in the jewelry market, which has so far been underutilized. Use the possibilities offered by the variety of diamonds offers: Stand out from your competitors with brown diamonds. Here you can request a selection of cognac diamonds. Call us toll-free.

The special feature of the diamond market: Black diamonds

When we talk about black diamonds, we do not go into the realms of the mafia or on dark jewellery paths, but of remarkable gemstones. According to information from newsletter "Diamantbericht", black diamonds have been in vogue since the last Basel watch and jewellery fair. Whereas previously only a few Italian or progressive goldsmiths used black diamonds in their collections, the black diamond, a special feature of the gemstone market, now seems to be experiencing a flight of fancy.

A diamond is not only imperishable, it is also known as "the king of crystals", symbolizing the sun of our solar system. Thanks to its fire, the diamond is also known as the "stone of innocence", which emphasizes purity, durability and loving open nature. Because of its optical effects, high hardness and rarity, the diamond was the stone of kings. But for some time now a diamond has been in vogue that cannot be said to have all these properties. We are talking about black diamonds.The employees of the German Gemmological Society from Idar-Oberstein were astonished when they were presented with the first black stones, which proved to be diamonds in the X-ray diffraction diagram. The hardness of the black diamonds was also astonishing, far exceeding that of the white diamonds. The black diamond as a gemstone must not be confused with the Bort, which is also in great demand in industry for its hardness for grinding and drilling purposes. The black diamond is of African or Indian origin.

Black is the colour of the night, but also of the mysterious, as secret as the current owner of the probably most famous cut black diamond, the "Black Star of Africa" (202,00 ct). Also secret is the whereabouts of the "Black Diamond of Bahia" (raw 350 ct), which was shown in 1851 at the Crystal Lalace exhibition, with the remark "... too hard to grind it". The black diamond, in its kind an unusual gemstone, has always been a peculiarity for the gemstone connoisseur. In the past they were used for cultic purposes, but today the black diamond finds more and more jewellery lovers.

The Black Diamonds collection by Chopard, launched in 1998, heralded this trend. Earrings, rings, necklaces and watches have been decorated with black diamonds. With the help of white and yellow diamonds, Chopard has brilliantly managed to give the black diamonds a proper validity. In the Black Diamonds collection, black and white brilliant-cut diamonds are combined in an effective and tasteful way without appearing ostentatious. But here you can also see the only disadvantage of black diamonds. A black diamond has no fire, which is why it is rarely used as a solitaire. Always it needs the help of some white brilliants to bring a black diamond to the fore.

Diamonds owe their colour to their chemical elements. The strength of the stone is emphasized by a brilliant cut and it makes possible that entering light is reflected by the table. The black diamond, however, has its colour enclosed within itself, making the cutting and polishing process considerably more difficult. Diamond cutters often have to re-cut the stone because it can break up to ten times. The effort is worth it. The cut black diamond is characterized by a high gloss. Together with the black of the diamond one has the impression of metallic luster.

Undoubtedly the fact can be accepted that one can create unusual jewellery with black diamonds, as the current trend shows. This trend is also confirmed by Robert Brachfeld, Diamantgroßhandel Brachfeld/60598 Frankfurt, who has been offering a large selection of black diamonds for some time now. Unusual, creative and mysterious jewellery creations always find a grateful clientele.

Goldsmiths can order a selection of black diamonds in all sizes and cuts on memo.

So yellow diamonds are graduated from GIA. We have also adopted these names for our diamonds.

Natural or treated color diamonds? Natural fancys are extremely rare. It is estimated that for every 10,000 colourless diamonds there is only one valuable coloured specimen. Since colours have a strong optical appeal and coloured stones are therefore often used in jewellery production, the demand is much greater than the supply of natural colour diamonds, which explains the sometimes horrendous prices, which we will go into in more detail shortly. A cheaper alternative is to make less valuable diamonds artificially coloured in the laboratory. However, such a treatment must be indicated in the certificate.

In the past, a very simple way was chosen to make diamonds appear more colorful: The surfaces of the stone were simply colored.

But then the physicist and later Nobel laureate Marie Sklodowska Curie discovered polonium and radium. From then on, the diamonds were colored by irradiation. Although the results were of higher quality than the superficial colouring, these stones had a decisive disadvantage: they were highly radioactive - and that for a long time to come.

This is why particle accelerators (cyclotrons) were later used. The radioactivity of the treated diamonds was degraded faster, but the colouring was not satisfactory.

In the 1970s, a new method finally came into play: the so-called HPHT treatment. This abbreviation stands for "High Pressure - High Temperature". The diamonds are exposed to very high pressure and high temperatures (1,500 to 3,500 degrees Celsius). This process ensures high quality for jewellery production.

Another method that we also use imitates nature by replacing the heat, pressure and time under the earth with a simple accelerated electron beam. The result is the same. The electron beam forces the boron and nitrogen atoms to replace some of the carbon atoms. The crystal structure is then rearranged. The white light is distributed and we are then able to see a variety of beautiful bright colors. Nothing has been artificially added and the color is permanent. The process does not use radiation and there is no radioactivity. It is completely safe and complies with all applicable regulations.

Press Comments

Diamonds are for eternity and are characterized by their imperishability and hardness. Rough diamonds also impress with their naturalness and individuality. Since they are untreated, no two stones are the same. Their surface is cloudy and rough - but it is precisely in this supposedly imperfect appearance that their charm and fascination lies. Like man himself, a rough diamond has corners and edges. Many creative goldsmiths use them to create beautiful pieces of jewellery. We supply rough diamonds in all sizes and qualities. Also different forms are no problem for us. So we always have in stock: octahedrons, balls and cubes.
