Composition of white gold
Contrary to the popular belief that white color is always achieved by joining such precious metal as platinum in the creation of white gold as rule involves a completely different ligature or impurities in the form of copper, silver, nickel, zinc or palladium in the compound with 58.5% of natural gold.
Ligature is a concept characterizing the alloy of precious metal and impurities that are designed to increase its strength.
Unlike silver, white gold has a lighter cold hue and has special strength characteristics that give it the above mentioned elements. Combining gold and silver to produce a white alloy is completely unacceptable, it gives the material softness, reducing its strength characteristics. Having stumbled upon a similar product, it is necessary to refuse its purchase.
More expensive admixture – softer alloy
interesting that with the reduction of the sample the product acquires additional strength characteristics, that is why in the production of wedding rings from white gold involves a material of 500 or even 375 samples.
White gold of a high 750 sample, which is an alloy with platinum, is used to create filigree works of art not intended for daily use. Interestingly, this kind of white gold does not darken, is not corroded, and retains an excellent appearance for years.
It is platinum or palladium that give the product such a high price characteristic, but not only due to its high cost, but also due to the labor intensity of the alloy process itself.
White gold is of two kinds: noble – with impurities especially expensive metals, and ordinary – with copper, nickel impurities.
Alloys of other metals can cost a lot thanks to the artfully executed work and the skill of a jeweler who undertook to create a work of art. White gold products, which have not too refined ligature and are of wide consumption decorations, type of stamped rings, earrings or simple piercings, have much lower lower value despite the color of the gold applied.
