This adaptable length necklace has fun elements on it with a lariat resemblance, anyway instead of passing one side through a ring, this one clasps or in a designed site on top of the "rescued" copper and sterling horse link or on any of the links along.
The focal cascade, a multi-element composition, starts with that vintage sterling and copper ex-earring element rescued and reinvented to hold a curved textured Sterling link, and from it, a ring rustic style that holds a glass bead with hints of blue fire. The beaded ring holds a fun element: a hollow Sterling industrial tubular form that has inside a Mexican fire agate in granular raw form embraced by clear resins to give the tubular shape. -That was fun to make!-
The chain, all in Sterling, holds South Sea natural tinted pearls and, on one side, two large reticulated discs with a yellow tinted quartz spike and an oragne raw kyanite spike. On the other side, a solitaire disc holds a blue titanium quartz spike in a Sterling cage. 
 
Boho and dramatic, mobile, colorful, and young, to be worn by itself or stacked  it measures around the neck in its conventional style, approximately. 24 1/2 inches, and its cascade measures, from the link on top where it would clasp to the bottom, 5 3/4 inches
The pictures on the bust show its approximate length, how bold it looks, how the focal cascade shows on the chest, and how it would look on you since it is a real human sie mannequin.
