Gemologist, Diamonds & Fine Jewellery Since 1971
Buying a gemstone is often a very different experience than buying a diamond. Gemstones are bought based on favorite colours, wardrobe matches, personality, and fashion trends. While gemstones are judged using the 4Cs, just as diamonds do, each is judged separately. For example, a sapphire is compared to another sapphire, but wouldn't be compared to an emerald or aquamarine. Choose your gemstone jewellery based on your personal preferences.
We sell a number of different shaped gemstone jewellery. Some of our most popular shapes include round, marquise, oval, pear, princess, and baguette.
Gems are cut in a variety of different ways. Transparent stones will often be cut with facets. Unlike diamonds, the facets are planned to maximize the colour. Other stones like jade, opal, and onyx will be cut into a smooth domed shape known as a cabochon. While still other stones like cameos are intricately carved.
Gemstone colour is different from judging the colour of a diamond. Every gemstone has a range of colour that runs from light to dark and more vivid to less vivid, with a small range of colour considered preferable. All of the families of colour are represented by gems of different types.

Gems also have internal characteristics called inclusions. Some gemstones are known for having many inclusions like emerald or for having few inclusions like citrine. Each gemstone will be graded for clarity differently.
Like diamonds, gemstones are measured using carats. A carat is equivalent to .2 grams or .007 of an ounce. Unlike diamonds, each gemstone has a different density which greatly contributes to the weight of the stone.
We take pride in offering great value and quality. In order for us to offer this value, it is necessary to buy and sell diamonds in weight ranges. To help assist you in understanding these ranges, we have provided the following chart of size tolerances.
Published by the American Gem Trade Association.
Enhancement: Any treatment process other than cutting and polishing that improves the appearance (colour/clarity/phenomena), durability, or availability of a gemstone.
N: The "N" symbol appears on the chart only for natural stones which are not currently known to be enhanced; however, the "N" symbol can also be used for other natural gemstones in the event that a gemstone has received no enhancement and the seller will provide a guarantee that there has been none.
E: The "E" symbol indicates that a gemstone has undergone its traditional enhancement process.
The use of heat, light and/or other agents to lighten or remove a gemstone's colour.
The use of such surface enhancements as lacquering, enameling, inking, foiling, or sputtering of films to improve appearance, provide colour, or add other special effects.
The introduction of colouring matter into a gemstone to give it new colour, intensify present colour or improve colour uniformity.
The filling of surface-breaking cavities or fissures with colourless glass, plastic, solidified borax or similar substances. This process may improve durability, appearance, and/or add weight.
The use of heat to effect desired alteration of colour, clarity, and/or phenomena (if residue of foreign substances in open fractures is visible under properly illuminated 10X magnification HF should be used.
The use of heat and pressure combined to effect desired alterations of colour clarity and/or phemonena.
The impregnation of a porous gemstone with a colourless agent (usually plastic) to improve durability and appearance.
The use of a laser and chemicals to reach and alter inclusions in diamonds.
The filling of surface-breaking fissures with colourless oil, wax, resin, or other colourless substances, except glass or plastic, to improve the gemstones appearance.
The use of neutrons, gamma rays or beta particles (high energy electrons) to alter a gemstones colour. The irradiation may be followed by a heating process.
The use of chemicals in conjunction with high temperatures to produce artificial colour and/or asterism-producing inclusions.
The impregnation of a colourless wax, paraffin, and oil in porous opaque or translucent gemstones to improve appearance.
