Featured here is an original vintage platinum diamond engagement ring that is truly one of a kind! The center stone is an Old European cut diamond that boasts gorgeous old world sparkle. It is a bright white stone that is 100% clean to the naked eye with no visible inclusions. It is a great SI3 diamond as any natural internal characteristics are white/colorless and blend very well with the sparkle of the stone. One of the diamond's inclusions touches the surface of the stone. This slight surface inclusion is protected by its setting and concealed by a prong. It has no affect on the longevity, nor the wearability of the ring. The center is complemented by two round diamonds that are bright white and even better than eye clean as any inclusions are difficult to find even under 10x magnification. The ring is in good condition and is believed to have been crafted in the 1930s. This gorgeous three stone ring will make a wonderful heirloom engagement or cocktail ring! The ring was made completely by hand from solid platinum. The measurements are 5.1mm across (north-south) and 6.2mm from the finger to the top of the ring. Make this gorgeous original vintage diamond engagement ring part of your collection before it has been sold! It is a one of a kind heirloom piece that cannot be replaced!
