This exquisite Heidi Daus necklace is a true masterpiece. The faceted beaded design, combined with a stunning trio of interchangeable magnetic pendants, makes it a versatile piece with multiple options. The necklace is 15.75” inches with a 3.75 extender with a closure ensures that it will stay in place. The beautiful pendants are also interchangeable with the ring that I don’t own. But, the measurements for each are: Oval: -1-3/8"' long x 1-1/4" wide x 5/8"' high. Pear: 1-1/4" long x 1" wide x 1/2" high. Square: 1" long x 1" wide x 1/2" high. Perfect for any occasion, this necklace is a must-have for any fashion-forward woman.
