Excellent Experience.
Professional right from the start, with much intelligent communication back and forth, every question answered quickly. Shipping was accurate and fast and I live in Canada, the auction house is in New York City, no issues at all... and when I received the Ring, it was simply stunning and exactly as advertised, even better in person. Thank-you Adi and team, job well done. Kevin.
