Ceramic Flower Frog Ikebana Coral Shamrock

Vintage ceramic flower frog with a very unique shape. It reminds me of a piece of coral or a shamrock. There's some crazing within the glaze and one corner has a tiny chip on its glaze, shown in last photo. Color is a pale green with hints of yellow and gray. Measures about 5.5" by 5.25" and 1 5/8" tall.
