Agate

A generally accepted requirement in the definition of Agate is that it has to be banded. This qualification distinguishes it from other forms of Chalcedony which are not banded. Exceptions include Dendritic Agate and Moss Agate, which are not true Agates since they lack the banding patterns, but they are still traditionally called Agates since they have more than one color. Onyx, when banded white and black, is technically a form of Agate, and Sardonyx, which is a banded reddish and white Chalcedony, is also technically a type of Agate. Some forms of Carnelian may also exhibit banding and can therefore be classified as both Carnelian and Agate. Deposits where Agates are commercially mined are usually very extensive, thereby enabling this gemstone to be affordable and inexpensive. However, a fine and sharp banded pattern, combined with natural strong coloring, will quickly increase the cost and value of and Agate. Specific Agate localities will provide similarities in banding style and color, thereby lending many Agates a geographic prefix. Other variety names used will connote specific colors or patterns, such as Fire Agate or Eye Agate. The history of Agate production is closely tied to German town of Idar-Oberstein, which has evolved as an important gemstone center. Agates and Jasper were historically found in the Idar-Oberstein region, and cut and polished by local craftsman. With the discovery of the enormous Agate deposits in Rio Grande do Sul, Brazil in the 1800's, the new material was shipped to Idar-Oberstein for cutting and polishing. The local Agate cutters of Idar-Oberstein were well-suited for this job, having been historically trained in this profession. Idar-Oberstain remains today as an important cutting and polishing center.One of the most plentiful and varied stones on Earth, Agate is found in nearly every colour in the rainbow and ranges from translucent to completely opaque. This beautiful stone belongs to the Chalcedony family, and is a relative of Aventurine and Carnelian. Opaque Agate is called Jasper. Agate can be found in many shapes as it is easy to cut and polish. We have a variety of Agate, including red and black striped Botswana Agate, patterned orange Crab Agate, dappled green Moss Agate, and more.

Amethyst

Amethyst is a violet variety of quartz. The name comes from the Koine Greek αμέθυστος amethystos from α- a-, "not" and μεθύσκω (Ancient Greek) methysko / μεθώ metho (Modern Greek), "intoxicate", a reference to the belief that the stone protected its owner from drunkenness.[1] Ancient Greeks wore amethyst and carved drinking vessels from it in the belief that it would prevent intoxication.

Amethyst, a semiprecious stone, is often used in jewelry.

Emerald

Emeralds are a beautiful green gemstone, although are a slightly less common choice for rings than sapphires and rubies. Reaching 7.5–8 on the Mohs scale, the beryl mineral is softer than rubies, sapphires and diamonds, making them a marginally less cautious choice for engagement rings – which should be able to withstand life’s daily activities. Emerald gems are, however, a particularly enchanting choice of centre stone, and as they remain an uncommon choice for engaged couples, the green stone offers a unique edge. The lush, verdant hues are caused by traces of chromium and sometimes vanadium.
