"Antique jewelry object group: bar brooch Condition: excellent condition Country of origin: Although it does not carry any legible control marks we believe this to be of Belgian origin. Style: Fifties (of the twentieth century) Style specifics: This type of jewelry is very specific for the fifties of the twenthieth century. As platinum was used a lot, the Art Deco period only 30 preceding and still used as source of inspiration, it is (even for the trained eye) sometimes very hard to note the difference between Art Deco and Fifties. Period: ca. 1950 Material: platinum and 18K white gold Diamonds: One old european cut diamond with an estimated weight of approx. 0.55 crt. 100 single brilliant cut diamonds (also called 8/8) with a total estimated weight of approx. 3.00 crt. 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. Total diamond weight: approx. 3.55 crt. Precious stones: Six triangle shaped sapphires . We did not check if the sapphires are lab produced or not as this information has no influence on the value of the brooch. Natural sapphires and lab produced sapphires were both used in this era, rather more for their effect then for their intrensic value. Birthstones: Diamond is the birthstone (or month stone) for April and sapphire for September. Hallmarks: No trace. Dimensions: 6,17 cm (2,43 inch) x 1,20 cm (0,47 inch) Weight: 10.00 gram (6.43 dwt) Reference N: 12198-0004 Copyright photography: Adin, fine antique jewelry "
