I am Fred Koss, founder of FK Diamonds and private diamond broker in Cincinnati. I have been in the diamond business for over 35 years, and I will find you any size and shape certified diamond and any setting (even custom designs) for far less than a retail jewelry store.


I always beat retail prices (even their “sale” prices). Always.

You are crazy not to consider Fred Koss before spending big bucks on a major investment like a diamond. He got me exactly what I was looking for at about 20% less than I would have paid at Bluenile.com and 30% less than a retail store.  I have a few grand in my pocket now that I would not have if I used anyone else.

My wallet and I can’t thank Fred Koss yenough for helping me purchase an engagement ring. I spent a lot of time in local jewelry stores, but I quickly learned that he could make my ring budget go much further. He delivered a superior grade diamond at a significantly lower price than any retail store.

The diamond engagement ring I purchased from Fred Koss is amazing. His personal concern and interest in helping me made his service absolutely the best. He made the total experience more like a friendship/partnership than a buyer/seller situation.

My experience purchasing my fiancée’s engagement ring through Fred Koss of FK Diamonds was outstanding! He was extremely easy to work with. No one could beat his prices — he saved me a substantial amount of money on a top-quality ring.
