Looking like lace or embroidery,these have a very Spanish Colonial look... This very abstract style of earring is known to be worn by "Tehuana"women (Juchiteca ) of Oaxaca,which is the style/region that Frida Kahlo made so popular & put on the map for their costumes & jewelry. This type of jewelry from Oaxaca, is actually derived from 18th century Spanish & French influences.
Their shape & style, are a cross between the Oaxaca's"El Eme"(M) earring and the Yalalag Cross(If not familiar,please Google). 
Taking approximately 3 days to make,the base is made from scratch & the filigree being made of super fine sterling wire.The wire has a circular pattern & not once, do you see the pattern losing form.Surrounding the pearls,Carlos added a 'diamond cut" technique,that will sparkle when the light or sun hits them.Because the wire is so delicate,this is what allows them to be more 'wearable' & even though they are a larger size,they are of a lighter weight.
