Although we always try to label treated materials appropriately, buyer discretion is advised. Please ask our staff if you have any questions regarding a particular material or item of stock.

What does “treated” or “heat treated” mean?

Heat treatment is considered a fairly natural enhancement as it is a continuation of the processes that occurred in the earth when the stone was originally formed. During treatment the stone is heated to very high temperatures which can cause the colour of a stone to lighten, darken, or to change completely. It can also bring about an improvement in clarity and brightness. Heating is detectable only by trained observers in a laboratory setting and is usually irreversible.

There are some gemstones that would not be as readily available if not for heat treatment. For example; the abundance of citrine on the market is actually the result of heat treating amethyst.

What does “oiled” mean?

Oiling of emeralds is pretty universal, but not every emerald is oiled. When the rough emerald is mined it is thrown into a barrel of oil; when it is cut, oil is used as a lubricant on the cutter’s lap. The colourless oil seeps into the fissures on the surface of the emeralds and when the fractures contain oil of a similar refractive index they are less visible to the naked eye. To complete the process oil is pressurised into the fissures of the polished stone.

What does “irradiated” mean?

Irradiation means pounding material with subatomic particles or radiation. Sometimes irradiation is followed by heating to produce a better or new colour for the gem. Blue topaz is the most common example. Although blue topaz does occur naturally, it is much paler in colour than treated topaz and more expensive.

What does “stabilised” mean?

Stabilisation is the introduction of a bonding agent, usually plastic, into a porous material. Some gems are also waxed on the surface to enhance colour and lustre. Stabilised turquoise will not break as easily and will not absorb oils and discolour as untreated turquoise may.

What does “dyed” mean?

Dyeing of chalcedony/agate and of pearls is prevalent, permanent and is generally considered acceptable practice. These colours do not occur in nature are usually pretty easy to spot, although the fact that they are dyed should always be disclosed. Dyeing of other materials however; for instance jade, lapis lazuli, turquoise, rubies, emeralds and sapphire is sometimes done to disguise poor quality goods.

Cultured freshwater pearls grow naturally in a limited selection of colours. Most colours other than white and pale shades of pink and peach can be assumed to be dyed and should be labelled as such. Dyeing can usually be detected by looking for concentrations of dye around drill holes or around blemishes. Other kinds of cultured pearls such as southsea pearls and tahitian pearls may grow into a variety of exotic colours naturally because they are grown in a different variety of oyster.


Are your products ethically sourced?

We are very concerned with ethical issues surrounding the stones that we supply and we try to source stones ethically as far as possible but with such a large and varied stock it is almost impossible to track where every individual stone was mined and cut. Coloured stones often go through many different hands in many different countries before they eventually arrive in the UK.

What is a mabe pearl?

A mabe pearl is a hemispherical shaped pearl which is grown against the inside of the oyster’s shell, rather than within its tissue. Once grown, the nucleus is removed and replaced with resin and they are then given a mother of pearl back.

Although mabe pearls do occasionally appear in nature, all our mabe pearls are cultured.
