I don't often see filigree rings in 14 K yellow gold. This is a ring from the 1940's for that reason. It is a lovely and bright @0.33 CT Old European Cut Diamond in a white gold surround and yellow gold mount. Often in vintage rings white gold was used to set off the Diamond and yellow gold was used for the majority of the ring.
The ring is size 6.75 and weighs 4.1 grams. It can be sized by your jeweler if needed. The Diamond is 'H' in color and VS2 for clarity. When you compare my ring to others the extra weight to the ring attests to superior craftsmanship and quality.
