With gemstones, the earth gives us its most beautiful treasures. Such as imperishable diamonds, blood-red rubies, intense green emeralds, and deep blue sapphires. Aquamarines in the colors of the oceans, purple amethysts, golden yellow citrines, tourmalines in all colors of the spectrum, blue-purple tanzanites, and much, much more. And in the oceans, rivers, and lakes the pearls shining like silk are born. By the way, come and visit this site ()

Gemstones have always appealed to the imagination. Wars were waged for it, alliances were made, friendships sealed, and in recent centuries, above all, love was crowned with it. Many precious stones adorn religious objects such as miters, tiaras, monstrances, and tabernacles, as well as noble crowns and cups. The majority of these art treasures come from the Middle Ages. Visitors to museums and exhibitions are often rightly amazed at the enormous riches that the church and nobility possessed at the time, but also at the matte sheen, the few sparkly colors, and the small life that the gemstones radiate. At the time, many gemstones were already tried to improve color and clarity. Thanks to its porosity, the naturally grey-brown agate could thus be stained into intensively red, blue, or green stones. The natural cracks in an emerald were filled with oil and made almost invisible. Under some gemstones, mirrors, colored papers, or pieces of cloth were placed or they were hollowed out from below to accentuate the color. Over the centuries, these methods, and other newer ones, have been refined to improve the appearance of the naturally imperfect gem. That development is still ongoing. Gemstones have also been ‘counterfeited’ (synthesis) with special equipment for over a century. Just as silk and wool are dyed, they are stained and leather is made from skin, so a gemstone also needs professional support from people. He grinds the raw stone supplied by nature in such a way that the internal brilliance, the play of colors, and the fire become visible to everyone. Gemstone cutters have been experimenting with this for centuries and new, even more, refined cuts are still being developed. But sometimes a perfect cut is not enough.

Diamond

This gemstone appeals to everyone’s imagination. As the hardest natural material on earth, the diamond is the ultimate symbol of durability and love. Most diamonds are cut in a round 57-faceted model, which was designed in 1917. This brilliant-cut gives the diamond its maximum beauty: the sparkling fire and its brilliant appearance. Diamonds are judged by 4 C’s: Carat Weight, Cut, Color, and Clarity. Diamonds completely free of inclusions are highly valued. Although natural inclusions reduce the value, they are also proof of authenticity. Larger, somewhat darker inclusions can reduce the diamond’s brilliance. In such a case, the diamond can be treated. A laser is used to drill a channel (thinner than a human hair) to the inclusion, which is then dissolved or bleached with a special chemical. The borehole and cavity are filled with a vitreous substance; they then become practically invisible. Fracture surfaces that reach the surface of the sten can also be filled in this way. Although the stone looks more beautiful after treatment than before, it does not increase in value. In addition, it is a bit more sensitive to bumps. In addition to the colorless, there are diamonds in various natural colors, from yellow to brown to pink and blue, and even red. The completely colorless and intensely colored toes are extremely rare and therefore very valuable. But the color of diamonds can also be manipulated. By irradiation with convection heating, or the recently developed high pressure/high-temperature treatment can give slightly tinted diamonds a more intense color or be made colorless again. The artificially colored diamonds, often yellow or blue, and pink, are cheaper than the naturally colored stones. It is important that you as a buyer are informed of any treatments. In addition to natural diamonds, there is also a synthetic diamond in gem-quality on the market. Due to the high production costs, the prices of these stones are currently not much lower than those of the natural stones. It is important that you as a buyer are informed of any treatments. In addition to natural diamonds, there is also a synthetic diamond in gem-quality on the market.

Ruby

The blood-red ruby ​​is one of the most precious gems. Since time immemorial, this gemstone has stood for ardent love, leadership, power, and unimaginable wealth. In nature, very few rubies are found without disturbing inclusions and with an evenly distributed intense color. Especially in the countries where they are found, it has been customary for centuries to improve the color and clarity of the stones by controlled heating. The lesser qualities, with cracks and fracture surfaces, are filled with a glass-like substance during the heating process.
