Is anyone familiar with Kaynar? I am newly engaged and my engagement ring is my great grandmother's and I am trying to find out a little more about it. It is white gold, with a miner's cut diamond, inside the band it says "kaynar" ? I have googled this and found several "kaynar white gold rings" but it doesnt tell me anything about them. Has anyone heard of it? Is it a style of ring, a jeweler or a type of white gold?

We haven't taken it in to get it appraised and insured yet (i know!) will be doing very soon and I am sure who we take it to will be able to tell us alot, but just curious if anyone knew so I didnt have to wait as long. We estimate the ring to be from the 20's or 30's...

thanks ladies!

I just Recived the same ones Today?! i have been searching all over for this kaynar 14K white gold?!?    please if you do find something out let me know. my grandparents got married in 1968 so im guessing this might be how old they are  I have no idea!

In 1902 Mr. Kirchner and Mr. Renich started a jewelry company in Minnesota. "K and R" became their "Kaynar" trademark.  The family company lives on today as Kirchners Kaynar Diamond Company, or simply Kirchner's, in Minneapolis.
