The Swedish Royals have an absolutely amazing jewel collection which they wear often, beautifully, and somewhat interestingly.

However, unlike their Danish or Dutch friends, they have rarely adapted old jewels into new configurations.

There are beautiful Sapphire, Aquamarine, and Opal brooches that could either be hung from a diamond chains, or inserted centrally into multistrand pearl necklaces (think - Diana's pearl and sapphire choker).

Additionally, there are rarely worn emerald pieces that really should be made into a tiara.

I wonder if there is a lack of ingenuity, because there certainly isn't a lack of appreciation!
