Mikasa (?) crystal and satin floral cake plate

This is such a lovely cake plate, I believe it is Mikasa, but not certain. Measures 13 1/2" in diameter. It has a 3-D relief of blossoms and leaves on the underside, and is reverse painted in soft pink accents on the flowers. (photo does not show true color) Top side is smooth. Glass varies from satin to clear on the plate and designs. Legs are part of the formed flower buds. Perfect condition. An amazingly pretty presentation for your special party.
