See Schurmann (1990), pp. 120 & 121, pl. 32 for an example of this type of Karabagh rug, the example with only one column of rhomb medallions and differing border design but a highly comparable colour palette of which Schurmann states 'The harmony of colours in this rug is deserving of particular attention.'
