Solid 18kt gold. Looks very dark almost like 22kt. The emeralds are super clean and have amazing green color. All natural Colombian emerald cut emeralds. A mixture of different sizes in the stones so it’s hard to say the exact carat weight. By my calculations I’m estimating atleast 4 carats of emeralds. It could very well be more. Only true way to know would be to pop the stones out. Vintage piece over 50 years old. Retails 5000$ my price is negotiable.
