Diamond shape (7)

Ross

I think it could be either:

rhombus

lozenge

'diamond shape' is the definition.
(I've seen this before)

This is all the clue.

(Other definitions for lozenge that I've seen before include "Diamond-shaped parallelogram" , "Medicinal tablet" , "Medicinal sweet" , "Medicated sweet" , "Pastille; rhombus" .)

I've seen this clue in The Independent, The Telegraph, The Times and The Guardian.
