Our Portraits are artistic representations of people. They can be created in any media, from traditional oil paintings, to photographs, sculpture and even mixed media. Our Portraits can show part figures, usually showing the sitter's head and shoulders, but they can also depict the whole figure. They can also illustrate more than one person, in a group portrait.
Our artist aims to show the sitter's appearance as well as some elements of their character. Our Portraits often relate to a message, which our artist wished to relay, such as the beauty of a woman being wooed by a king, or the wealth and power of a monarch etc

Emerald is a gemstone and a variety of the mineral beryl colored green by trace amounts of chromium or sometimes vanadium. Beryl has a hardness of 7.5 8 on the Mohs scale. Most emeralds are highly included, so their toughness is classified as generally poor. Emerald is a cyclosilicate
Californium is a very strong neutron emitter. It is used in portable metal detectors, for identifying gold and silver ores, to identify water and oil layers in oil wells and to detect metal fatigue and stress in aeroplanes.
it is an actinide element, it is a silvery white radioactive metal with chemical symbol of CF
Its a purple variety of quartz (SiO2) and owes its violet color to irradiation, impurities of iron and in some cases other transition metals, and the presence of other trace elements, which result in complex crystal lattice substitutions.The hardness of the mineral is the same as quartz, thus making it suitable for use in jewelry.
