The Mohs Scale is used to determine hardness, Hardness is a measure of a mineral's resistance to abrasion and reflects the atomic structure of a mineral. Generally, high scratch resistance is desirable for gemstones, and a Moh's hardness of 7 or higher is important. The principal reason is that a common cause of abrasion is sand, which is silica grit (quartz), and is commonly present in dust. Stones which are softer than quartz are not suitable for everyday use as facetted jewellery gemstones, particularly in rings, although many are beautiful and attractive.
Some gems, such as pearls, coral, turquoise, lapis lazuli, amber, and opal are quite soft, but are usually polished into cabochons or beads, rather than facetted, and therefore do not show scratches so easily.
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. The procedure can take 3-6 weeks. 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. If necessary we can supply stones on approbation(appro) for you to show your customer under no obligation to buy. 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.

The correct method to describe the position of missing stones.
Wherever possible try to describe the position of the stone relative to the hallmark. In order for the position of the stone to be accurately described it is essential that all parties hold the ring the same way up. Firstly you will need an eye glass so that you can read the hallmark on the ring. Look at the hall mark through an eyeglass and hold the ring in front of you so that hallmark is the right way up with the head of the ring on top and facing towards you.
