This small cross is a common design seen in 18th Century artwork, similar to the one shown in the first image (Woman in Blue by Thomas Gainsborough). This cross is a small, subtle size measuring about an inch long. 

It is made with vintage Swarovski Crystals for lots of sparkle despite the small size. 

The setting is nickel free and is made with brass plated in your choice of Silver or Gold (Silver is shown). 

This pendant looks great on a narrow black silk ribbon, which is available here:
