This is a whole family of charges: what I have need of just at present is "gorged with a wreath of oak".

Typical is that the object round the neck of the lion is on a slant. E.g. this image of the Duke of Wellington's arms:

Some research turns up options like these: crowns of many types; collar; collar with chain; label. May occur also as "lion rampant collared or" etc.
