Vintage 14K Gold 1.12CT TW Diamond Blue Quartz Stud Earrings - Posts with Nuts

Made of 14K White Gold (hallmarked on nuts only - earrings tested), may I offer this pair of stud earrings featuring a diamond accent (1 point to the top of the 5.5mm (55 points) faceted ice blue Trillion cut gem. At first I thought the stone might be Blue Topaz but the gems tests in the Iolite/Quartz range of my Presidium. Could they be Aquamarine? The stone is definitely one I am unsure of but with the diamond, they make for one wonderful pair of studs (posts with nuts). Front design measures 3/8" high x 3/8" wide. Total gemstone weight is 1.12CT TW approx. Combined weight of the pair is 1.4 grams. Lovely condition with no problems I can spot. NOTE: I use a mini mannekin for display. To be sure of the size of what you see on your computer screen, please read the measurements carefully in the description, take out a ruler and gauge for yourself whether the piece is right for you or not. I like to avoid disappointment when items arrive and Buyer thinks they had purchased something smaller or larger than what they thought they saw.
