Materials
Acting responsible towards the natural world means being completely transparent with materials we use when creating our jewelry pieces.
About Metals
14 Karat Yellow Gold
Contains 59% of pure gold, as well as ligatures: copper, silver and zinc. No plating.
14 Karat White Gold
Contains 59% of pure gold, as well as ligatures: copper, silver and zinc. The white color is achieved through adding nickel to the alloy. The natural shade of the alloy is yellowish, that’s why the jewelry piece is additionally plated with rhodium. It may become thinner with time and thus the color of the metal will become warmer. It is recommended to renew the plating every 3-4 years.
Sterling Silver
Contains 93% of silver, as well as copper and zinc in the form of ligatures. Every silver piece is plated with rhodium. With no proper care the metal can get darker with time. As a rule, it can be easily fixed by polishing with a jewelry cloth.
Gold Plated Sterling Silver
Contains 93% of silver, as well as copper and zinc in the form of ligatures. First off, it is covered with palladium base and then plated with 99.7% fine gold several microns thick. With no proper care the metal can get darker with time. As a rule, it can be easily fixed by polishing with a jewelry cloth. The gold plating can get thinner with time, and completely thin out in the spots of excessive friction. It is recommended to renew the plating every 1-2 years.
Metal Purity Confirmation
Each Leta jewelry piece is required to be verified by a state agency – the Federal Assay Chamber, where the composition of the metal is analyzed using spectral analysis. While hallmarking is not necessary for silver jewelry, it’s required for gold pieces. The Assay Chamber is hallmarking every piece independently from manufacturer.
In addition, since 2022, all Leta jewelry pieces are being registered at GIIS DMDK – a unified database for precious metals and stones. Every piece has its unique number printed on a tag. With this number you’ll be able to trace its entire path from production to the current owner, also find information about its full composition and manufacturer.
About Allergies
Can Silver or Gold Cause Allergies?
The reason for an allergic reaction to a piece of jewelry is not gold or silver, but the ligatures used in the alloys. The most allergic metal is nickel used in white gold. However, its content is insignificant. Besides, the Leta white gold jewelry pieces are always covered with rhodium, which is hypoallergenic and protects skin from contacting alloys.
