Too bad there are no original photos. @Glitterbomb purchased her bangle in 2021, so it's pretty new. I purchased mine in early Feb 2022, and it has those markings in the same place.VCA is not consistent with hallmarks at all. Mine was on the white gold part that clasps inside and not under the serial number.
@Glitterbomb The XS and Small sizing was already changed by the time you got your bangle, so that negates that sizing confusion theory. Another mystery.
