I am listing a vintage pair of J-Hoop Tanzanite and Diamond Earrings in 14 Karat White Gold. They measure approximately 0.65 inches long by just under a quarter of an inch wide at the widest point so work well for everyday wear. The tanzanites are 6 x 4 mm ovals. Below the tanzanite is a medley of small white diamonds. I count 9 diamonds per earring (18 total). The diamonds are small and are prong-set. Unfortunately, I don't know the exact carat weight of the tanzanites or the diamonds. However, I estimate that the tanzanites each weigh approximately .5 carats (or 1 carat total weight). I am the original owner of these earrings and purchased them at what used to be a shopping store called Hechts that closed many years ago. I bought them because they were affordable for me and have good color for the size of the tanzanite. I also like the millegraine work below the tanzanites. The earrings weigh 3.0 grams on my scale. The earrings are both clearly marked "14K AU" (14K gold) and "TZ," which I assume is for tanzanite. The butterfly backings are both 14K, but they don't match. I must have lost one of the backings and replaced it. These earrings are pretty. I have not worn them much, and they are in very good pre-owned condition. Thank you for looking at this listing. Please feel free to let me know if you have any questions about these earrings and check out my other listings.
