I bought this huge studio vase the other day because I liked it. Carrying it to my car gave my muscles a good workout

It is 39 cm high, 15.5 cm across at the rim, and about 20 cm at the widest point. It has what appears to be silver aventurine under a clear casing. There is a chunky applied rim. The signature may be acid etched, I am not sure, perhaps Hanley. The base is ground flat.
Any ideas of who made it? I hope the pictures help. Thanks.
