Vintage jewellery is jewellery that is not old enough to be classified as antique (100 years or older), but is also not modern or contemporary. It usually refers to jewellery made after the 1930s and includes Late Art Deco, Retro Era, Hollywood-inspired 1940's jewellery, Jacqueline Kennedy-inspired 1960's jewellery, and even dramatic jewellery from the 1970's and 1980's.
In the early 1900s, diamond cutters began to experiment with new techniques. A breakthrough came in 1919 with the introduction of the round brilliant cut. Due to its ability to maximize fire and brilliance, the round brilliant cut has become the standard and most popular way to cut diamonds. Like the old European cut, a round brilliant cut diamond has a circular girdle and 58 facets. However, the round brilliant cut lacks a culet. The round brilliant cut became prevalent during the Art Deco and Retro periods.
Old Mine Cut Diamond
Diamonds with this cut possess a squarish girdle with gently rounded corners. Old mine cut diamonds have a high crown, a small table, and a large, flat culet. They are similar to today's cushion cut. The old mine cut dates to the 1700s and was most prevalent during the Georgian and Victorian eras.
The element platinum derives its name from the Spanish Platina del Pinto which translates to 'little silver from the Pinto' (said to be a river near Popayan, Columbia in which alluvial platinum was first found by the Spanish Conquistadors). Its white metallic luster leaves little doubt as to why the Spanish chose the name.
Platinum belongs to a group of elements, fittingly called the platinum group of metals. Apart from platinum the group comprises Osmium, Iridium, Palladium, Rhodium and Ruthenium. Platinum is often found as natural alloys containing one or more of these other elements and it wasn't until 1804 that all but one of the elements were isolated and named.
Platinum is malleable, ductile and very strong. In addition, it does not tarnish and it doesn't corrode making it a highly prized metal and extremely suitable for the manufacture of fine jewelry.
