The 3-D design is so beautiful with rhinestones triple layered to resemble flower heads as the focal point of the necklace and earrings. The incredible colors are another reason for the strong attraction. The rhinestones are superb, saturated with color and so bright they mesmerize.
"Trifari", the necklace is adjustable and has a "J" hook. I totally agree with Julia Carroll's sentiment about the "Memo" ad. In her "Collecting Costume Jewelry 202" p. 226 she writes "This advertisement features some of the most beautiful jewelry Trifari produced".
