Jewelers frequently employ precious metals and stones, but contemporary jewellery can be made from a variety of materials. As a result, traditional jewellery models take on a more contemporary look. Contemporary jewellery, in contrast to classic jewellery, reflects the tastes of the day. This provides the jewellery a distinct personality that places it between fashionable high-street jewellery and traditionally made works of art. You'll need both specialised training and in-depth subject knowledge to create contemporary jewellery. The contemporary aesthetic honours historical creativity while incorporating new innovations.
Topaz is a gemstone which, throughout history, has shared its name with all other yellow gemstones. It was not until the mid 18th century that the name was assigned to the aluminum fluor-silicate that is uniquely topaz. During the 16th century Cellini described a (most probably) yellow sapphire as "topaz". Due to its close resemblance in color to citrine, yellow to orange "actual topaz" were termed "precious topaz" to distinguish between them. Topaz comes in many hues, from colorless to yellow, blue, brown, red and everything in between. The colorless and pale blue stones are most abundant in nature, followed by yellow and brown stones, while the golden-orange, pinks and reds are most rare. The latter are mostly mined in Brazil.
Brilliant Cut Diamond
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.
Because of the softness of pure (24k), it is usually alloyed with base metals for use in jewelry, altering its hardness and ductility, melting point, color and other properties. Alloys with lower carat rating, typically 22k, 18k, 14k or 9k, contain higher percentages of copper or other base metals or silver or palladium in the alloy. Copper is the most commonly used base metal, yielding a redder color.
