This neck chain almost matched a wrist chain that I wear, and I thought they were compatible in size (I'm a bit challenged in the millimeter dept.). I was wrong, this excellently crafted and stunning neck chain was about 5 X the cross-section of my wrist chain. Because I intended to wear both daily, I had to send the neck chain back because I could not easily wear a dress shirt and tie with it -- its 20" length and BIG dimensions made it difficult to button the top button and tighten the tie. If I were younger or had a non-dress-up dress code for work, I'd have kept this neck chain.
