Based on an ancient glyph, or at least inspired by one, this vintage Los Castillo Mexican silver and azur-malachite inlay necklace is out of the workshop's "mozaico Azteca" line of jewelry. Centuries old, the technique became almost obsolete during the Colonial period but was revived by Chato Castillo, one of Taxco's most talented, innovative and original maestros. The coloration of the stone here leans towards the greens and taupes with rich blues present here and there to add that visual surprise and cajole the eye. The necklace came to me with one earring (it will come to you the same way) and thankfully so because for some reason the Los Castillo signature is on that piece while the rest of the familiar hallmarks for the famous workshop are on the necklace. Measuring 15" long (wearable) by 7/8" wide, the necklace wieghs 78.1 grams (earring is and additional 4.5 grams). The duo is signed with Eagle 3 assay mark, des. no 233 and "MADE IN MEXICO STERLING" on the necklace while the workshop's signature and Eagle 16 can be seen on the earring as shown. Both pieces date in the 1950s-60s and are in very good vintage condition with beautiful colors in the azur-malachite inlay, nice patina in the silver-work (you can always polish a little, if you wish) and no damage noted except for a tiny little pop in the inlay of one link; it is positioned on the back of the neck when the necklace is worn and very difficult to find with a naked eye - I only became aware of it after going over the whole piece several times with my jeweler's loupe.
