HM continues to dole out the jewels she thinks it is appropriate to, to the younger members of the family. She has been very generous in what she has provided Camilla, Catherine, Sophie and Anne.
There will always be the question of can she share more with them. Unlike the Dutch and Swedish system where a reasonably large number of royal ladies have access to a "common pot", the British and Danes tend to be quite specific in who is allowed access to what. This, to me, makes the jewels a bit more personal, and to some extent, helps retain an air of exclusivity around them.
