Turquoise Circlet Pin of 5-Petal Flowers, Unmarked

It's very nicely made; it has a unique (to my understanding) latch on the pin-keeper. No indication of maker, nor of metal content. It's ~1 inch in diameter. I don't think it's old. What do y'all see here?
Thanks for lookin'!

 

There's nothing unique about the clasp. A fiddly early 20th century safety clasp with a tendency to open on its own unless the latch really closes with a snap. I see the flowers as forget-me-nots.

 

Agreed, and I also see Persian turquoise. I’d get that tested.

 

I dunno...it's either paint, or enamel. Great color, but not the stone. Sigh.

 

1910s enamel forget me not, sweet! 10 or 14k

 

I'll look again for an assay mark...thanks for the date, kyra!

 

You’re very welcome
Mark should be on the catch

 

Sweet, and I'm with kyra, of course.

Ditto. These clasps were used from ca 1890-1920, and as you say, an early safety clasp.
