Prussian blue? Grayish blue? Slightly-purplish-gray-blue? Who knows? And with a locket this gorgeous, who cares! Depending on the light you'll get different delicious shades of grey blue, but always banded by delicate bands of white. The machine-turning underneath the translucent enamel is perfection, the inner circle with a converging lines motif, while the outer ring balances the ever-popular machine zigzags with gentle inward curves. Open up the locket and you'll find it all original with the perfect place to show off your own treasure: maybe a photo of your favorite person.
Condition: Excellent antique condition. Marked `WA' and `800' (the number being a reference to the amount of silver in the piece, 800 parts per thousand, sterling silver is 925/1000). The marks are too small and incomplete to be sure, but I think that the most likely origin is Italy, since they commonly used this type of `800' mark with little oversight and a lack of standardization for the rest of their marks. Opens and closes smoothly, and has one inner snap-in rim to hold a photo. Measures just over an inch across and 1 ½" long.
