Hi,
Queen Olga of Greece owned a set of at least 4 diamond star brooches. She wore them on her bodice or even on her head.
Grand Duchess Helena of Russia, married Prince Nicolas of Greece and became the daughter-in-lay pf Queen Olga. I've found no photo of Helena wearing the stars but...
Princess Marina, Helena's daughter, wore a set of three diamond stars (one large and to smaller). She wore them on her head, her dress or her belt.
And Marina's daughter, Princess Alexandra also wore a set of three diamond stars, most in her hair.
So, a possibility that these stars came from Queen Olga ??
Side by side, Marina's and Alexandra's stars seemed to be more pointy that Olga's.
Please, tell me what you think.
