Cabochons Emerald for retail sales at retail pricing. Smaragd cabochons are sliced with a curved tip, usually in a round or egg-shaped one. These types of cuts show the stunning color and give you a great big rock at a fabulous cost. They are ideal for hanging in trailers or for making a high arched ring.
Search for gems that have a bright colour first, then search for bumps or tears. Colour is the most important characteristic of an emerald, not light.
Might some gemstones be cut as cabochons?
A cabochon in the gemstoneworld is a rock that is ground with a high-gloss polish, round or convex surface without facet polish and a shallow or slightly curved bottom. Cabochons can be sliced in any form, the most frequent being the ovals. It originates from the word caboché, which means "button" or "small dome".
So it is much easier to make a cabochon than to slice a facetted stone with many faces.
Prior to the development of the facetting technique, all gems were made as Cabochon, although some were also elaborate made. Facetted gems appeared in Europe's jewellery in the latter part of the thirteenth and early fourteenth century. At the end of the 19th century, with the emergence of the horizontal rotating cutter at the end of the 19th century, the opportunity arose to design and repeat complex geometrical facet patterns and thus to control and amplify the lighting from the inside of the gem.
Why were cabinochons still made when multifaceted precious stones were available? This is an interesting issue because different precious stones are used as cabins for different purposes. The reason in many cases is that the gemstone has particular characteristics that only become visible when it is ground as a cabochon.
For example, gemstones exhibit visual effects such as asternism (star effect), chato yancy (cat's eyes effect), iridescent (e.g. opal) or adular rescence (e.g. moonstone). If the gemstones are not transparent, they are not facetted but rather sliced as a cabochon. Also inferior materials of gemstones such as saphire, ruby and garnets are used as cabins.
When the stone has a very good colour but is not clear or clear enough to be facetted, it can still be formed and buffed into very appealing convercours. It' also customary to grind soft stone than cabins, as gemstones with a firmness of less than 7 (on the Mohs scale) can get scratches from crystal quite well.
Smallest scrapes show much less on a cabochon than on a facetted rock.
