None of the pieces produced by ALZA BARCELONA S.L., contain nickel in their composition. The absence of nickel, combined with the production systems we use, are the quality guarantee for our customers.
ALZA BARCELONA only uses primary materials of the highest quality, our crystals and zirconate are selected from the most prestigious international businesses, and we employ strict quality control before any of our products are distributed.
At present we have baths for silver, 18 carat gold, 14 carat gold and ruthenium. We also have four colour finishes to choose from, all of which are 23 carat gold. This final "dip" guarantees that colour tone of the previous baths will be maintained. The process is quality controlled in our own laboratory.
