Antique circa mid to late 1800’s this piece is in excellent condition. The collectors dream. 14k gold with patina and Russian hallmarks. The rosecut diamond is approx.85-1.1 cts. I don’t want to remove the diamond for an accurate weight therefore carat weight and grading is approximate. VS2, I/J by todays standards though this rosecut is unlike any contemporary rosecuts. The extraordinary high dome is the highest I’ve seen, hence the name.
