Style: estate jewelry (more info on styles) Period: ca. 1940 (events and facts in 1940) Source of inspiration: arrow Theme: An arrow perforating three bars of lapis lazuli. We do not have the faintest idea what symbolism could be behind this. Material: platinum and 18K yellow gold (more info on precious metals) Diamonds: 11 semi-modern brilliant cut diamonds with a total estimated weight of approx. 0.33 crt. Their cut is semi-modern as the stones are polished around 1950 which means that although to todays standards they are considered to be modern brilliant cuts, their cullet (the point at the bottom) are still polished flat. Note: All diamond weights, color grades and clarity are approximate since the stones were not removed from their mounts to preserve the integrity of the setting. Precious stones: lapis lazuli (more info on precious stones) Birthstones: Diamond is the birthstone (or month stone) for April and lapis lazuli for September.
