Precious metals and their alloys

We have summarized the most important criteria for determining the quality of precious metals for you.

Gold colors

Yellow gold – classic and elegant
Jewelry in yellow gold comes closest to the color of fine gold. The alloy consists of gold, silver, and copper. The mixing ratio determines the color. Yellow gold is considered elegant and classic and is the most popular gold color worldwide. It is a perfect match for blondes.

White gold – stylish and kingly
White gold is created by adding discoloring metals. It is slightly grayish and is therefore usually plated with rhodium. Thus it receives its brilliantly white color and it is more scratch-resistant. We use palladium as an agent; the cheaper price of silver and copper compared to palladium explains the difference in price concerning white gold in comparison to rose gold and yellow gold. White gold blends well with brilliants. Diamond jewelry in white gold is exceptionally gorgeous because the diamonds do not reflect any other color and thus their glow develops beautifully.

Rose gold – on-trend an flexible
Rose gold (sometimes: red gold) is a gold alloy consisting of fine gold, copper and small amounts of silver. The reddish color is due to the comparably high copper ratio. Rose gold currently is in full vogue and more and more women and men appreciate the delicate color hue, which flatters every skin tone.

Gold alloys

18 karat gold (18k, 750/-)
14 karat gold (14k, 585/-)
8 karat gold (8k, 333/-)








Gold alloys make jewelry more durable and robust. They include gold, silver, copper and palladium; the mixing ratio determines the individual gold color. We can create different colors from rose gold and yellow gold to silvery white gold. A premium-quality alloy with more than 70% of fine gold results in a beautiful gold color. Therefore we mainly use high-end alloys with 750/-18 karat gold. After all, we want our jewelry to be of high quality.

Alloys with an assay of 14 karat /or about 58% pure gold respectively) include less fine gold. 8k, 14k, and 18k are the most common alloys for jewelry manufacturing. However, we do not offer jewelry with 8 karat because we consider it to be inferior. For silver jewelry we use 18 karat gold plating.

By the way: Allergy sufferers need not worry: Our white gold, yellow gold, rose gold and silver are nickel-free.


Sterling silver (silver 925/-)

Silver 925/-, the so-called sterling silver, consists of 92.5% silver and 7.5% of other metals, mainly copper. Thus it is more scratch-resistant and harder than pure silver. Jewelry, coins, goblets, and prize cups may be manufactured from sterling silver. A slightly darker patina may occur over time.


Platinum 950/-

Platinum is rarer than gold and thus more expensive. Due to its high own weight, the excellent durability, and the unique purity it is perfect for jewelry. There is hardly any wear and tear. Platinum is not hard but tough. A platinum alloy including 95% platinum and 5% wolfram increases its hardness, yet it may scratch. A golden ring of the same size weighs much less than a platinum ring. This explains the higher price.
