Materials

Which materials are used for Retina-Jewelry ?

We only use sustainable precious metals of best quality

GOLD

Gold (18 karat) is guaranteed to be non-corrosive (no tarnishing, as it is possible with silver or 14 carat gold). For 18kt white gold, the only possible color change is when the optional rhodium-plating wears off (but can be renewed, as for silver).

Rotgold ist eine Goldlegierung, der Kupfer beigemischt wurde, dies lässt je nach Anteil Roségold oder Rotgold entstehen. Da Roségold manchmal sehr schwer von Gelbgold zu unterscheiden ist, verwenden wir das stärkere Rotgold.

PLATINUM

Platinum is the rarest, heaviest, most precious metal. It is used in 95% purity and is ca. 30% more dense and therefore much heavier as compared to gold. It will never change its color and is as light in color as rhodium-plated white gold. It is very robust and therefore the most popular precious metal next to 18 karat gold, with red gold experiencing a very high demand during the last 3 years, due to its attractive warm red color.

SILVER

Silber is the lightest (both weight and color), softest and cheapest precious metal. Unfortunately, it is corrosive, meaning it will tarnish over time (which can partially be prevented/delayed by rhodination). Due to its softness it will get much more easily scratches and wear marks as compared to gold or platinum.
A galvanic treatment on the surface – rhodination –  wears off over time especially for rings, (less so for pendants/earrings due to less mechanic abrasion) but can be repeated (cost ca. 80 chf).

ECO-GOLD

Our jewelry protects the planet’s resources

Since 2015 we are the first goldsmiths in Basel, using 100% Oekogold® and being re-certified each and every year. Oekogold® is a fairtrade-sign for ethically correct trade and sustainable use of precious metals: By this certificate and further ethic-codices  we guarantee that our gold, silber, platinum, palladium as well as copper as metal used for alloys do not directly come from a mine, which is known to harm man and nature. Our precious metals come from a  Swiss refinery, which uses recycled gold in order to refine it and use the single alloys for the production of new alloys.

Therefore, the gold, platinum, silver or palladium used in your piece of jewelry derives from credible sources and definitely not from regions of conflict.

These precious metals therefore are traded fairly and help protect our nature in a sustainable way.

Also metals used for creating alloys are obtained ecologically

Contrary to other gold-fairtrade-labels,  the Oekogold®-Label makes sure, that also metas used for creation of alloys (silver, copper, palladium), which often make as much as a quarter of your piece of jewelry, are ecologically obtained and traded in a fair and sustainable way.

Gold obtained from mines destroys our nature

The mining of gold – unlike Oekogold®-refining – always leaves a footprint in our nature, no matter if declared as fairtrade or otherwise: A ton of rocks often yields as little as 0.2 bis 8 g fine gold. Toxic substances are used for this matter  (cyanide, mercury). On top, some mines use up to 150.000 l water per hour to wash out the gold from the toxic mix.

Diamonds

Diamonds of highest quality

The media are full of reports about blood diamonds from  african countries who use and sell those for financing their civil wars. Other countries trade diamonds to finance terror attacks. We obtain our diamonds exclusively from 100% trustworthy sources, either from the diamond exchange in Antwerpen or the commodity exchange London. Working together with our suppliers over many years has built the trust needed to guarantee you only the best and finest qualities of materials.

Therefore we guarantee you, that all diamonds are traded ethically correct and 100% free of conflict. So you can enjoy your diamonds with the best conscience.
