Antique jewelry object group: engagement ring (or anniversary ring) Condition: excellent condition Country of origin: Although it does not carry any legible control marks we believe this to be of Belgian origin. Style: Interbellum - The interwar period (1918-1939) is understood, within recent Western culture, to be the period between the end of the First World War and the beginning of the Second World War. This is also called the period between the wars or interbellum. Style specifics: The Interbellum is the period between the two World Wars and one can recognize a transition from the Art Deco style to the Retro style. Period: ca. 1930 Material: 18K bi-color (yellow and white) gold Extra information: Diamond is the birthstone for the month of April, and besides being the most popular gemstone for engagement rings, it is also the anniversary gem for the 10th and 60th years of marriage. Even though the diamond is the hardest of all gemstones known to man, it is the simplest in composition: it is common carbon. The ancient Greeks believed that diamonds were splinters of stars fallen to earth. It was even said by some that they were the tears of the Gods or perhaps crystallized lightning or hardened dew drops. The exact origin of diamonds remained something of a mystery for centuries. In ancient times only kings wore diamonds as a symbol of strength, courage and invincibility. Over the centuries, the diamond acquired its unique status as the ultimate gift of love. It was said that Cupids arrows were tipped with diamonds which have a magic that nothing else can ever quite equal. But it wasnt until 1477, when Archduke Maximillian of Austria gave a diamond ring to Mary of Burgundy, that the tradition of diamond engagement rings began. Even the reason a woman wears it on the third finger of her left hand dates back to the early Egyptian belief that the vena amoris (vein of love) ran directly from the heart to the top of the third finger, left hand.
