4Cs: The universally accepted elements of diamond quality: Colour, Cut, Clarity, Carat.


9k gold: 9 parts of 24 gold (37.5%)


14k gold: 14 parts of 24 are gold (58.3%), but stamped as 585. It’s popular in the US, however Australia follows the English standards of 9k and 18k gold


18k gold: 18 parts of 24 are gold (75%). This is the most popular gold caratage worldwide in white or yellow for diamond settings.


24k gold: 24 parts of 24 are gold (100%). Popular in Asia and the Middle East, particularly in chains and bangles. It is however too soft to set diamonds into.


Accent stones: Gems that surround the centre stone to ‘accent’ or enhance its appearance.


Asscher cut: A square shaped diamond with step facets and small table. It resembles a square emerald cut diamond.


Baguette: A rectangular shaped diamond with step facts. It tends to be a long stone and is often used to compliment a centre stone.


Band: The metal ring to which the diamond is fixed.


Bar setting: A setting style that divides stones by metal bars on the ring band. This setting is very popular with those that have problems with claws catching on to their clothing.


Bezel setting: A setting style where the ring metal partially or fully surrounds the stone, forming a frame-like appearance.


Blemish: A surface imperfection on the diamond, which may or may not be visible to the naked eye.


Branded: A diamond with a patented cutting style.

Brilliant cut: A round diamond cut consisting of traditionally 58 facets.


Cathedral setting: A traditional setting style using arches of metal to secure the diamond in place.


Carat: A term used to describe the weight of a diamond. One carat equals one fifth of a gram in weight. The word comes from the carob plant whose seed consistently weighs the same.


Certificate: A laboratory-supported report which describes the characteristics and measurements of a diamond or precious stone. It is particularly important today to determine whether a stone is natural or synthetic.


Channel setting: A setting style that includes smaller diamonds set into a channel in the ring band.


Colour: Shades and tones of diamond colour rated from D (best) to Z (worst).


Cut: The geometric qualities and angles of the diamond, which impact its light reflection and overall quality.


Cushion cut: A square cut diamond with rounded corners, resembling a cushion shape.


Clarity: A measurement that notes the number and severity of a diamond’s imperfections, ranging from flawless (FL) to severely included (I3).


Claw: A popular setting style involving small metal arms to hold the diamond in place. Also called a prong setting.


Cluster setting: A setting style involving several (usually smaller) diamonds set closely together, giving the impression of one large stone.


Cloud: A term used to describe an internal imperfection within a diamond.


Crown: The section of diamond between its girdle and its table.


Culet: A facet at the bottom of a diamond.


Depth: The distance from the culet to the table of the diamond, or the stone’s height.


Eye clean: A term used to describe a diamond with no inclusions visible to the naked eye.


Emerald cut: A rectangular-shaped diamond with the corners taken off.


Exclusion: External imperfections on the diamond, also called blemishes.


Face up: A viewing position where the diamond’s table is faced towards the viewer.


Face down: A viewing position where the diamond’s pavilion (or point) is facing the viewer.


Facet: A flat surface on the diamond that reflects light.


Fancy cut: A term used to describe diamonds that aren’t round.


Fire: A term used to describe flashes of colour when reflecting light.


Flawless: The highest rating on the clarity scale. Flawless stones have no visible imperfections at 10x magnification.


Fluorescence: A term used to describe whether a stone emits a glowing effect when viewed under an ultraviolet lamp. In real terms, a high fluorescence stone will look bright in artificial light and dusty in daylight.


Flush setting: A setting style where the diamond(s) is set into the ring band without protruding. Also called a gypsy setting.


Girdle: The outline of a diamond, or its perimeter.


GIA: The Gemological Institute of America; a non-profit research institute and authority on gems.


Halo setting: A setting style featuring a border of stones surrounding the centre diamond in a circle, often creating a floating effect.

Round cut: The most popular diamond shape.


Scintillation: A term used to describe the visible sparkle of a diamond in motion.


Shape: A term used to describe the physical shape of the stone.


Solitaire: A term used to describe a piece of jewellery featuring a single stone.


Synthetic: A laboratory-grown diamond, also called an artificial, cultivated or cultured diamond, that has the molecular structure of a natural diamond.


Symmetry: A term used to describe the proportions of a diamond and position of its facets.


Tension setting: A modern setting style which uses the tension of the ring band to secure the stone in place.
