Cut

The cut of a diamond is all about unlocking the most out of the stone using the art of gemstone cutting, which has the greatest influence on overall appearance and sparkle. This involves fashioning the stone so its proportions, symmetry and finish reflect light to achieve the maximum ‘brilliance’ (reflected white light) ‘fire’ (spectrum of colours) and ‘scintillation’ (sparkle and the pattern of light and dark areas within the diamond).

Shape

Often confused with the shape, the cut refers to a diamond’s proportions and facets.
The cut is the process undertaken to transform the rough gemstone into the finished gem yet the shape represents the finished form such as round, heart or marquise.
The most popular shape of diamond is the round brilliant cut, however there are many shapes to choose from and each shape has its own unique appeal and advantages.

Blaze of light

Diamonds cut too shallow or too deep do not reflect light as efficiently to the top of the stone and may show black centres or a bow tie effect. An ideally cut diamond reflects the light up to the top and displays a blaze of light and spectrum of colours.

Proportions and facets

The cut of a diamond, its proportions and facets determines the light dispersion and has the greatest influence on overall appearance and sparkle. Precise craftsmanship is required to fashion a stone with ideal proportions. A well proportioned round brilliant cut diamond will have between 57 and 58 facets.

Light in, light out

Well proportioned diamonds maximise on the light in and out of the stone. As the only characteristic not solely influenced by nature, the cut can be exposed to human error. At Fultons we understand this, so you can be assured that we only select the finest gemstones for your jewellery.

Cutting it

The cut of a diamond can be graded ranging from excellent to poor and is the factor which is determined by human intervention rather than by nature.  Generally the higher the grade the brighter the stone’s appearance.  The cutting system is mathematical and optimises fire and brilliance using ideal proportions.

Carat

The name carat is derived from the carob tree as the seeds were of a constant weight, 1ct equals 1/5th of a gram

Clarity

Diamond clarity refers to the absence of naturally occurring inclusions within the stone or blemishes on the surface

Colour

Most diamonds can appear white to the natural eye but many display hints of colour especially on closer inspection.
