Which materials are used for our 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).

Gold alloys containing higher amounts of copper are called rose gold or red gold.

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

Silver 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).

This is how our jewelry protects the resources of our planet

Since 2015 we have been the 1st goldsmith in Basel to process ecologically processed precious metals. We thus guarantee ethically correct trade and sustainable extraction of precious metals: Our gold, silver, platinum, palladium and also copper as an alloying metal do not come from a mine, which is known to cause constant damage to people and the environment. We obtain our gold from a Swiss refinery, which processes it from scratch, e.g. from processing residues or old gold. The gold, platinum, silver or palladium in your piece of jewelry is guaranteed to come from harmless sources far from conflict regions. The extraction of these precious metals is sustainable for the environment and protects natural resources.
