The Queen and her ancestors have also believed you can’t have too much gold in a Palace. As well as solid gold objects, gold is the preferred frame for portraits, gold features in a lot of the carpets either as decoration or as the main colour and of course Her Majesty has some truly magnficient gold tureens. Silver plays a prominent part too with the silver staircase being considered the finest of its type in any universe. The Queen will not have cutlery in anything other than solid silver. Where gold is not used as decoration, silver is. And the Queen will often wear gold or silver themed outfits with matching jewellery. One way in which the realm has behaved honourably in its time is that it doesn’t steal precious metals from other worlds (though it will pinch ideas it thinks it can use). Gold and silver are mined throughout the realm. Naturally the dwarves ensure they get a very good price for it!
The Lord Chamberlain and Head Housekeeper are jointly in charge of caring for the Queen’s objects d’art and jewellery, in terms of cataloguing them and cleaning them. They use their own powers to clean these pieces saving manual cleaning for the less important works (and which is a useful task to assign as a punishment where necessary). Both take a huge pride in their work and the Queen’s most valuable pieces are probably the best cared for and cleaned items in any universe. Both deputize for the other where necessary. Both have run the Palace for centuries. The Queen couldn’t run her Palace without them. She allows herself the luxury of creating new jewellery items twice a year partly to help her two officers so they don’t have too much at a time to add to their workload and because she needs time to be creative and finds it darned hard to find that time.
