Colour and Clarity: In our opinion, the yellow diamonds are probably of intense to vivid saturation, VS2 to SI1 clarity. Other colourless diamonds are about F to H colours, mostly VS with few stones of SI clarity. Condition: Antique diamond brooch circa 1900, tarnishing to the metal with signs of wear and abrasions, very common in antique jewellery, overall in good condition.
