This is a Vintage English Bone China Royal Chelsea Pink & Gold Flowers Cup & Saucer Set Pattern # 51654.
Made in the United Kingdom in the early 1940s to 1950s.

This two-piece set is featuring a footed cup with a wide gold band on foot, scalloped rim and gilt trim, a beautiful gentle pink blush ground and bright gold floral design. This is the same design as Coalport pattern 9245.

Approximate dimensions:
Cup - 3" H, near 4.5" W with the handle, 3 3/8" at the top diameter, 8 oz of capacity.
Saucer - 5.5" diameter.

Good condition, free of chips, cracks or scratches, has some gold wear, mainly a spot on the underside of the handle, and some on the left side of the cup, as shown in pictures/video. Otherwise the gold is bright and shiny and produces a lot of reflection.
