Center is approx 1/2 Ct. Channel set are .03 x 20.All are colorless and eyeclean.

14 k SOLID 14k gold

Size 5

No paperwork

Center is 5.4 mm easily SI 2. Even SI1. But not a jeweler. Just been buying and selling diamond rings for about 15 years.

Honestly, a good buff and this would be easily retail for 35-4000 But again; not a jeweler. Nor am I one larger company that sells multiples of diamond rings on eBay. Meaning, I perhaps may make a mistake because I am human. Please be patient. Thank you.
