Beautiful Rhinestone Vtg. Strawberry Heart Brooch

Very beautiful Strawberry heart as you can see I took pictures with the flash and without the flash, when the light hits it it shows very shiny and different colors That's what it'll do when you're outside, then when there is no light it looks like the other picture I took still very beautiful. I did look on the back and took a picture of the back and as far as I can see there is no makers mark on it.
