Vintage engagement ring set with a 1.11 carat old mine cushion-cut diamond with GIA certificate stating the diamond is H color, SI1 clarity. Within a single-cut diamond and platinum step-mount. Circa 1925. 

The step-mount is a lovely added design element to be paired with a wedding band or worn on it's own.

Diamond and gold mining has caused devastation in areas such as Africa, wreaking havoc on delicate ecosystems and communities. Choosing to go vintage, you are eliminating the need for more mining and lessening the demand for new diamonds.
