I got these 3-piece linked brooches (called 'kerongsang' in the Malay language) from my late maternal grandmother but thought nothing about them until I read about old cuts on Pricescope. I'm wondering if the diamonds in these brooches are old cut diamonds, and if so what kind of old cut. My grandma was born in 1908 and these were probably given to her by her mother (my great grandmother).
I've attached a few photos. Your thoughts on these are greatly appreciated.
