Object Description

A magnificent, fine and impressive antique 4.45 carat Thai ruby, 1.90 carat Zambian emerald and 3.85 carat diamond, platinum, 9 and 18 carat white gold brooch; part of our diverse jewellery collections.

This magnificent, fine and impressive antique gemstone brooch has been crafted in platinum, 18ct and 9ct white gold.

The spray design features three revolving flower heads, each ornamented to the centre with a fine and impressive claw set round faceted cut Thai ruby; these rotating components indicate the high quality of the piece.

Each floral design incorporates eight lobed petals encompassing the feature ruby, each ornamented with two transitional modern brilliant round cut diamonds.

The elongated feature stem of the floral arrangement is ornamented with sixteen impressive channel set baguette cut Thai rubies, terminating with an impressive pear faceted cut Zambian emerald.

This antique brooch is further embellished with six conjoined wirework stems, each featuring a combination of individually claw set diamonds, Thai rubies and Zambian emeralds, representing the leaves and buds of the spray.

This fine and impressive antique brooch secures to the reverse with a hinged pin and catch.

This ruby and diamond brooch has been independently tested using state of the art technology (Niton XL2 Analyzer) and verified as platinum, 9 and 18 carat gold.

This impressive antique flower brooch with gemstones is supplied with an independent diamond grading report card*.

NOTE: * The Gemmological Certification Services (GCS) lab has verbally accredited the emerald originating in Zambia and verifies that the gemstone shows indications of moderate clarity enhancement, in addition to the rubies originating in Thailand with no indication of heating.

“Rather than regarding inclusions in coloured stones as harmful, in small sizes and numbers that do not in any way detract from their beauty, they should be regarded as adding to desirability, for they provide identifying characteristics.”
