(Sorry, this may be old news to some now but it wasn't posted here yesterday and many people are asking me what the blue diamond is).
Yesterday stardoll introduced a new type of member on their site. There are now non SS, SS and Royalty members. To become a royalty member you need to have been a superstar for at least a year, then you will be invited to the stardoll royalty club. (Want to read more about stardoll royalty? Click HERE)
To show that a member is a part of stardoll royalty they now have a blue diamond next to their medoll in various places instead of a star.
