Ring is 14k yellow gold, with a round deep blue zircon (a natural stone) set in four prongs. The stone measures approximately 10mm round and is estimated at 6.50 carats. Blue zircons are known for their amazing brilliance – much more so than blue topaz for example. The ring mounting is delicate, but elaborately carved, and appears to be hand crafted (as opposed to cast as most rings are). The finger size is 6 3/4, and can be easily sized. This would make a gorgeous splash of color on any finger, day or night. It’s not fussy, yet the engraved sides give it the unmistakable appearance of noblesse oblige. You can say it’s been in the family for years. 🙂 Weight is 2.9 dwt (or 4.5 grams). Inside the ring “14k” is stamped, along with what appears to be a “KE” stamp (possibly the maker) and hand graved inside are the numbers “3108”. I have not been able to find the significance. The ring shank measures approximately 4mm across at the flowers near the stone, tapering to approximately 2.2mm at the bottom. The ring is in very good condition.
