Brass is a metal alloy containing (at least 50%) copper and zinc Copper melts at 1083 Celsius and zinc boils at 907 Celsius and silver melts at 960 Celsius. Sometimes including small amounts of other metals, but usually 67 percent copper and 33 percent zinc. Formulas with varying proportions of copper and zinc are alloyed together colours to achieve different brass and different ductility (workability) of metal.

To give silver more durability when used in jewellery, it is combined with an alloy to change its physical characteristics. Sterling silver is an alloy with a fineness of 925, that is, sterling is 925 parts per thousand (or 92.5%) silver and 75 parts per thousand (or 7.5%) copper (the copper increases the silver's hardness).  

The gold plate is a thin coating of electroplated or mechanically plated gold on top of a base metal. 

Rhodium is a noble metal with a whitish grey appearance. Rhodium is typically applied to metal through the electroplating process. A thin plating of rhodium, which is one of the members of the platinum family, applied over either sterling or other alloy to give a bright, shiny, long lasting silver-coloured finish to a piece. 

Silver plating is a thin layer of silver bonded through an electrical process to a base metal core.  

Is the texture made by using any tool that leaves a mark on the surface of the metal, the list as long and as wide as imagination can go in the field of design and innovation.

Is a combination of two or more colour platings.  Example: plated with 18K gold and Rhodium, two kind of noble elements.

Gemmologists agree that Cubic Zirconia is the finest diamond simulation because it comes closer than any other gem material to the characteristics of a diamond. Like diamonds, the best cubic zirconia are colourless (or white) and do not lose their brilliance. Given proper cleaning, the cubic zirconia will retain its beauty for years. Almost all the cubic zirconia in the market today is chemically made of zirconium oxide and yttrium oxide. Individually, both of these materials are opaque, white ores, but when they are melted together under appropriate conditions, they combine to form an amazingly brilliant clear crystal. To fill the need for colours, manufacturers also produce a variety of coloured cubic zirconia.

Cubic Zirconia is cut in the same way as diamonds. The sizing of the gemstone is usually indicated by its weight in carats, a carat being one-fifth of a gram. Because the cubic zirconia is so dense and solid, it outweighs a diamond of the same millimetre size, weighing 1.7 times more than a diamond of the same millimetre diameter. We use the CZ weight in MBM copy, not the equivalent diamond weight.

Swarovski is an Austrian Company that makes high-quality rhinestones, beautiful cut crystals, costume jewellery, and other glass-related items. The company was founded by Daniel Swarovski (1862-1956), the son of a glass faceter. In 1892, Daniel developed a new mechanized technique for faceting glass crystals, creating a sparkling, diamond-like "chaton". He then started a factory (and company) in Wattens, Austria (in the Tyrolean Alps) in 1895. In the 1970's, the company expanded to the Providence, Rhode Island, USA - they later moved to Cranston, Rhode Island. In 1955, Swarovski and Christian Dior developed the iridescent aurora borealis stone. 

Synthetic Stone

Man-made, but having the same physical, chemical and optical characteristics as the natural stone. Synthetic stones are made in laboratories; these stones generally lack imperfections. It is very difficult to distinguish a synthetic stone from a natural stone.
