guide to

the four c's

When it comes to diamonds, there are four defining factors that determine its quality: Cut, Colour, Clarity and Carat. These characteristics will directly impact the lustre, sparkle and overall look of your diamond.

cut

A diamond’s cut refers to the balance of proportion, polish and symmetry to maximise the stone’s light performance. This is arguably the most important of the four C's, as the cut has the most significant effect on the diamonds appearance and sparkle.

colour

This refers to the natural colour or lack of colour visible within a diamond, not the coloured flashes of light the diamond emits when it moves, known as fire. Diamond Colour is graded alphabetically from D (Colourless) to Z (Light Yellow).

At EF Studios we work with D and E coloured laboratory diamonds, ensuring the brightest and best quality stones.

clarity

Clarity refers to how clear a diamond is, grading its purity according to the number of imperfections or inclusions present within the stone. 

Our EF Studios diamonds range between the VVS1-VS1. We strive to only work with the most exquisite diamonds that deliver on our commitment of balancing quality and affordability.

carat

Carat (ct.) refers to the specialised unit of measurement used to weigh a diamond and other gemstones.

WHAT ARE LAB DIAMONDS?

Lab grown diamonds are the exact same physical, chemical and optical properties as a mined diamond.

A lab grown diamond, however, is created above ground sustainably, with advanced technology mimicking the natural growth process of a mined diamond.

A laboratory grown diamond is the perfect choice for somebody who desires a real diamond with ethical origins.
