Antique Heriz /Serapi Silk Rug, circa 1900 Lush arabesque interlacing tendrils swirl across the ivory ground of this opulent silk Heriz. Ruby red and sapphire blue details shimmer against the ivory, nicely set of by soft cocoa outlines. In place of the massive border typical of Herizes, this example has three smaller borders in red and ivory to balance and contrast the coloration and grand scale of the field.
