Excellent condition solid 10k mens ring that was given to a high level Hewlett Packard employee (HP is here in Boise).  Nice genuine diamond.  I believe this was custom made back in the 90s. That would fit with similar info I read online about when Tiffany made some 10k mens rings, which hold up to wear better than higher carat rings that are softer.  This ring is in excellent condition.  Please take a moment to look through all of the photos for details and approximate measurements.  Feel free to ask any questions.
