An early 20th century platinum and 18ct gold opal and diamond brooch.

The lot is in good overall condition with light scratches in keeping with general wear. Very slight discolouration to gold. The diamonds appear bright and well matched, with very small, scattered dark inclusions. Individual diamonds too small to accurately assess colour/clarity grades. Principal diamond appears slightly lower colour grade than remaining diamonds. Please see important notices for purchasers in the catalogue and on our website for Coloured Gemstones. Opals to flower and bud appear well matched with green and blue flecks of play of colour. Opal to terminal appears a medium blue body colour with slight play of colour, possible replacement.
