Scientists can make Synthetic flawless crystals to grow in specific shapes and sizes. However, time and care are needed to grow the synthetic crystals, the equipment is expensive so gems cut from such crystals are not cheap. Rocks and Minerals have been used in jewellery and decorations for thousands of years the best known are Jade, Lapis Lazuli and Turquoise.
Organic Gems are those derived from animal or plants they include Amber (fossilized tree resin), Jet (fossilized compressed trees), Coral, Pearl, Ivory and Shells.
Repolish/Recut - on some softer stones e.g. opal, emerald and garnet the surface can wear away and may, after some years, need to be repolished or recut by a lapidary (a stone cutter). The harder stones such as diamond, ruby and sapphire can also chip or wear over time and these can also be recut. The cost price does vary according to the amounts of facets (surfaces of the stone) the size, and its hardness. In some cases it is cheaper to replace the stone than have a damaged stone recut.
Supply - we stock a large range of the most common gem stones and can supply a variety of grades and sizes. We have suppliers who can provide the more unusual stones. We can also supply and cut stones to fit settings if they are not stock sizes.
Setting Techniques - stones are secured into their settings by first cutting a seat in which the stone rests and then covering the stone from above with some additional metal. This traps the stone so that it cannot move down or up. The setter (the person who sets stones) has several options on how to secure a stone into a mounting. The most common settings are Claw Setting or Grain Set other styles are Rub Over, Pave, Channel, Illusion, Star Setting, Invisible Setting, Suspension Setting and Countersunk.
