Amazing mens 18kt gold and diamond ring, early 80's, excellent condition!

This gorgeous 18kt gold with a full carat of diamonds ring was designed as a one of a kind creation for my dad by Barnes Jewelers in Western Maryland, early 80's. The style of 'gold nuggets' was very popular in the 80's...shown on my husbands finger now in pics. Size 11. Total weight is 8.9. My dad wanted me to sell it as he has not worn it in years. Also have details on separate issues such as melt value, loose diamond info. for anyone interested in that. Any questions, please ask! Thank you!!!
