White gold is gold that has been alloyed with a mix of nickel, zinc, copper, tin, and manganese (and sometimes palladium). White gold was originally developed to imitate platinum during World War II (during this time in the US, platinum was considered a strategic material and its use was prohibited for most non-military applications, like jewellery making).

The term is sometimes applied to the ancient electrum. Before the use of platinum or palladium, white gold was often used as a setting for diamonds, being highly reflective and, unlike silver, not subject to tarnish.

These originated in the beech woods of the Chilterns around High Wycombe, where bodgers turned crude versions before passing them to craftsmen. The name can be traced to the 1720's and is now used for variations on the theme of solid moulded seat, turned legs and stick back with hoop or comb top rails. Sometimes there are nods to passing fashions, such as cabriole legs or the Oxford types, but the basic form persists into the mechanical age. Elm was commonly used for seats, and legs and spindles might be yew. A popular type from the mid 1800’s is the low back smokers bow.

Xalostocite is a pink grossular garnet that is found in a matrix of white marble.

Xalostocite is found in Xalostoc, Mexico

YAG is an acronym for yttrium aluminium garnet, a man-made imitation diamond.

This imitation stone lacks the fire of a natural diamond.

Tough, close-grained hardwood used for turning, particularly in chair legs, and in veneer

Zamak is an acronym for Zinc Aluminium Magnesium and Kopper.. Zamak is a zinc alloy containing some aluminium (3.9-4.5%) and copper (0.02-0.05%).

The addition of Copper and Magnesium will give to this alloy diverse properties allowing it to be used to cast parts in industries such as Automobile, Building, Electrical, Electronics, Telephony, Toys, Cloth & Sports, Decoration etc.

There are many advantages of this high pressure die casting alloy. Used in continuous casting process, this alloys has great commercial advantages as it is cheaper than Aluminium and Magnesium, easy to cast (behave like virtual water) and has many similar properties to the both other non ferrous alloys.

Zoisite (Calcium-aluminum silicate) is a grey-green mineral that occurs in cracks of igneous rock.

Zoisite has three known forms: Anyolite a green matrix containing rubies Tanzanite transparent, blue-violet containing strontium Thulite opaque pink crystals containing manganese

Zoisite was named for the Slovenian mineral collector Baron Sigismund Zois von Edelstein, who financed the expedition that discovered Zoisite
