The older jewels were garnets, the new ones are artificial rubies. The garnets have a greater tendency to shatter.
The pros did not like the jewel movement. If the jewel shattered, the key was out of service until a replacement could be had.
The first jewel movement keys had a top of the frame adjustment, but since this could be fussed with by a Lid, it was eliminated to reduce the incidence of shattered jewels. What you see on the newer ones is a platic insert that is not functional.
if bidding upon older deluxe keys, one wants to ask that the jewels be checked. Replacements are not free.
