The focal of this one of a kind necklace are spectacular beryl,  the deepest of blue seas, aka, Santa Maria aquamarine in a deeply saturated blue.  Named in honor of Santa Maria de Itabira, which is the site in Brazil where the first such stones were discovered in the 1950s. 
 
These gorgeous blue beryl briolettes sway in a cascading waterfall  beneath a bold, 42mm rose pendant of sterling silver, set with tiny marcasite for a dazzling effect.
 
The neck chain is composed of complimenting aquamarine roundels and gently oxidized yet polished links of sterling silver at 5mm, at a length of 20",  and is finished with a sturdy lobster claw clasp.
