JR's idea is alright. giving actual gems that can be converted to money at the person's discretion is more practical, and it works whether the recipient is male of female. Since the "Ruby Ring" is a common card, it stands to reason that they are a dime a dozen and would not be that big a gift to keep forever etc. etc..

I don't think the Governor or relative would have a piratey tendency to hoard things though ...
as for the ruby necklace, maybe it can be changed into a "ruby brooch". women can wear it, and males at the time wears cravats that also require a pin to decorate it ^^
