Vintage Victorian style bracelet with rose cut diamonds

This is a 14K hallmarked golden bracelet with rose cut diamonds set in silver and in the middle on both sites two sapphires. The backsite (as you can see on the fourth pix.) is also very beautyful decorated and what I admire to this back is the patience and the time which it must have cost the goldsmith. There are a lot of diamonds. I wonder what period of time this is. Someone told me it is probably of 1940/50.
Have you any idea?
