Introduction to lab roughs for lapidaries

Lab roughs are chosen for gem-cutting, otherwise known as lapidary to make into saleable and usable form. Loose gemstones are made up of crystalline structures that can be cut into desired shapes through faceting or cabbing and polished to reveal their lustre.

Lapidary roughs are chosen carefully for their ability to be cut into many smaller pieces of gemstone and for their carat weight, shape, and clarity. The cut that can be applied to a lapidary rough depends on its symmetry and surface area that a lapidarian can work with.

Gemstones can be cut with flat or round surfaces to showcase them in the best light and to maximise light refractory and colour.

A raw gemstone that has not yet been cut or polished can be lapidary roughs for wholesale or direct suppliers. The ideal shape can be cut from a lapidary rough by manufacturers of lab-grown gemstones or in factories. The 4C’s are maintained as best as possible for jewellery craftsmen who mount polished and cut gemstones onto jewellery pieces, before selling to consumers directly or via jewellery brands and retailers.

Lab-grown gemstones can be made to the ideal carat weight with top clarity and colour to allow for the perfect cuts. As most of the surface area is designed to maximise yield on cut gemstones, man-made counterparts of natural gemstones can better avoid wastage.
