Craftsmanship Details
High-quality casting with precision-cut vertical grooves; the transition between the textured shoulders and polished shank is seamless and well-executed.

Age Estimate

Value Estimate
$800 - $1,200 USD based on current gold spot prices (~$2,000/oz) plus a craftsmanship and design premium.
