Vintage 14k gold emerald cut CZ stud earrings

Purchased from a vintage antique/estate jewelry seller, so I have no insight regarding its original background. These stores will typically collect/evaluate/restore/resell pre-owned fine jewelry. If you like it, you like it :) Approximately 4mm x 5.5mm emerald cut cubic zirconia CZ studs set in 14k solid yellow gold. Marked 14k and a maker’s mark on the post. Vintage Store noted that the original 14k backs were missing and provided their own. .38 dwt Looks prettier in person. I loved these because I don’t trust myself w/ real diamonds in my ears - yet still prefer solid gold jewelry. I used these regularly for about half a year (NOT daily), but I no longer wear them as I currently prefer round studs and hoops. Excellent used condition and before sending I will run these through my ultrasonic jewelry cleaner (on light settings) .
