Lot 172
A mystery set sapphire and diamond brooch, designed as a long oval of mystery set calibré cut sapphires in a scallop edge border of round brilliant cut diamonds, unmarked yellow precious metal, clasp with safety catch, length 2.8cm, cased Other Notes: The setting of gems without visible support or metalwork - the 'serti mystérieux' - was a technique developed by several companies in the early 20th century, patents being taken out by Chaumet in 1904, and in 1933 by both Cartier and Van Cleef & Arpels - the latter company coining the term 'mystery set'. It involves reciprocating grooves and ridges in the girdles of flat-edged (usually square cut) stones so that they interlock , in much the same way as those children's puzzles with a frame within which movable squares must be slid around one space at a time to make a picture. The technique is difficult and expensive, so tends to be used only for valuable stones suiting especially sapphires and rubies - emeralds being too brittle and diamonds too hard. At first only flat settings were attempted, but Van Cleef & Arpels patented a method of setting curved pieces (such as this brooch) in 1938. Despite the popularity of platinum at that period, the precious metal used most often for the trellis backing and setting is 18ct gold, being more malleable and with a lower melting point . Mystery set jewels were at their zenith in the mid years of the last century, but are still being produced, and still most closely associated with Van Cleef & Arpels.
