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.
Tourmaline is a large family of minerals composed of a complex boro-silicate. The most common species of the tourmaline group is Elbaite (named after the island of Elba in the Mediterranean) and it occurs in all colors of the rainbow. It was first brought to Europe by Dutch traders whom also discovered its pyro-electric effect. When heated, tourmaline is electrically charged, this charge was used to attract ashes from a smoked pipe and these stones thus received the glorious name of asschentrekker (old Dutch for ash puller).
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.
