Monarch sterling opals are opals grown for color and impact.  This one really stole my breath, so I paired it with mermaid orb glass, sterling accent spacers, Czech glass, and tiny onyx spacers.
 
To present it best, I hand-knotted this on black silk.  The toggle clasp you see is .925 sterling silver as well.  This piece is 19".
 
Due ot the nature of its construction, we cannot resize it.
 
Lead/nickel free.
