Bridal Jewelery

A question for you girls...

a friend of mine who is getting married this year has asked me whether it is possible to have a set with a droplet (like the one H09170 posted) where the droplet can be changed (eg by a small screw attachment) to match the suit you are going to wear. she wants to get different coloured droplets with her jahez suits.

i think its a clever idea to cut cost of buying loads of jewelry, if its a possible thing though?
