The silver tone gourmette chain measures 17" ( 43.2 cm) from end to end and has an additional 3" (7.6 cm) of extender. The general length places the half moon petals at the base of the neck. The mix of textures and tones creates a myriad of additional colour perceptions as per the reflective qualities. As you can see in some of the photos, although the setting is all the same tone of coin silver, there is a rainbow quality to the metal depending on the angle of the light and what is reflected on the surface! Dots of silver separate in pretty arcs the clear marquis stone from the white bugle beads. Rippling along there is an arc of creamy opalescent faceted stones and towards the outermost edge is an arc of opaque and pale delphinium blue. The smaller half moons have a 5/8" max. width and the larger ones have one of just about one inch. x-posted
