Flint

This little one is older than me. I can’t say by how much. But its beauty has certainly held up over time.

Sterling set with purple and green "flint glass" a term that comes from a centuries old style known as paste. The simple explanation is that glass was mixed with a range of elements to produce certain shades and depth to mimic the appearance of gems. It was also a bit of an art form.

Metal marking exists. Barely visible. From a trusted seller. Which is why you’re reading about ancient glass. Size five. Incredible shine.
