Both necklaces have wonderful, imaginative beads, they are wondeful attempts, most are. It is my guess that the mustard yellow bead necklace, that all of the 'floral' rounds seen in pics are mass produced modern attempts (a different artist made them) while being mixed with the ovals and some rounds done by older artist. The clouds are what appear to me to differ between them, the overall style, the use of colors, the goldwire around the floral beads used as a border more so in the rounds then in the ovals. I like the age of the ovals and some of the rounds as 1920-1940's. The bottom necklace not much younger if any...thanks for sharing!
