I came across this awesome site the other day, www.invaluable.com. Its a premier online auction space that stocks the coolest jewelry, art and collectibles. I scouted a few items from the site that i like and here is how i would pair them.
A casual winter look like the one below would go perfect with the Natural 0.50 ctw Diamond Anniversary Men’s Ring which has 10K White Gold.
This look below is my favourite casual look and i would sport the 18k Yellow Gold Mens Ring with 1.00ct Diamonds and 0.05ct Ruby as eyes of the snake head. So cool!
