Queen Louise wore this tiara with five stars. But I'm not sure that the central stones are turquoise. picupload
Her daughter-in-law Princess Helena wore a five star tiara at the wedding of Princess Caroline Mathilde. It seems that this tiara was inherited by Princess Alexandrine and then by Alix von Miller zu Aichholz, née countess zu Castell-Castell.
But of the latter there is a coulor photo with rubies in the stars, not turquoise.
So either the stones were exchanged, or this is a third tiara. picupload
