RARE Vintage Krementz Mother of Pearl Cuff Links & Tuxedo Studs Set 1930-40's

Wow!! This is actually a rare fine.  These are from either the 1930's or the early 1940's.  They're in the original storage case, which is beautiful itself.  My understanding is that these are gold filled or gold plated and mother of pearl.   The center stone is white but has that mother of pearl iridescent shine. All items are sold as is, no returns, so please look at the pictures carefully as the pictures are part of the description.
