Antique Chinese rose famille cup and saucer

Beautiful and delicate antique Chinese export rose famille cup and saucer set. I'm not good at dating these because the marks are so confusing but appears to be late 1800's or turn of the century. Email me for the back stamp photo if you like. Cup and saucer decorated with panels of hand painted roses and foliage. Highlighted with gold accents. Cup is so thin and transparent you can see through it. Delicate spaghetti size handle on the cup. No chips, cracks or paint wear. Simply a gorgeous set! I would appreciate any added information if you have it.
