I bought this over a month ago but had it lengthened to 18 inches and was in Malaysia for a work trip for over 2 weeks so i'm just getting around to posting this 
it's the small Cobblestone pendant in both Rose cut and brilliant cut diamonds in platinum. it has a really nice weight to it and the two cuts of diamonds sparkle and scintillate really well together.
thanks for letting me share!
