How To Choose Your Diamond

White Diamonds

White diamonds are a traditional option that reflect our approach to engagement; minimal, classic, and timeless. Our white diamonds are hand selected to match our strong standards, with each stone meeting a high quality of brilliance, clarity and cut.

 

Champagne Diamonds

Our champagne diamonds are ethically and sustainably sourced from Australia’s renowned Argyle Mine. We are proud to celebrate a stone that shares the same heritage as our brand, and captures the natural hues and warm tones of the Australian landscape.

Australian champagne diamonds are graded against the Argyle Colour Grading Scale, ranging from a light Beige (C1) to dark chocolate (C7) in colour. The colouring is 100% natural, providing each stone with a unique shade and increased rarity. Our C4 champagne diamonds have been carefully selected to complement the warm tones of yellow and rose gold, and cut specifically to maximize colour and brilliance.

 

Colour

Diamond colour is determined through the use of an alphabetical grading scale that ranges from D (colourless) through to Z (light colour). This grading system is used to grade all white diamonds, which contain varying degrees of natural colour. Our diamonds meet a G grade, which ensures our diamonds look transparent even within a white gold setting.

Cut

The most important characteristic of a diamond is its cut. This feature determines the overall brilliance of the stone and amplifies the diamond’s unique dispersion properties. The cut is measured through a diamond’s proportion, symmetry and polish, ranging from ‘Poor’ to ‘Excellent’. When light enters a diamond, an Ideal cut will refract the light back through the table (top) of the stone, producing brilliance and fire. Our priority is to offer a diamond that is well proportioned, aiming to feature an ‘Excellent’ cut grade.

 

Clarity

Clarity refers to the visual appearance of a diamond in relation to internal and external blemishes. As a diamond forms, minerals create small marks and imperfections, making each stone unique. These are called inclusions. It is rare to find a diamond free from inclusions, however, the type and positioning of these marks is what makes no two stones the same.
The clarity scale ranges from IF (Internally Flawless) to I2-I3 (Included). The smaller the size and quantity of inclusions, the higher the clarity grade. At Sarah & Sebastian each stone is carefully scrutinised under magnification to meet our high selection criteria.

 

Carat

A carat refers to the total weight of a diamond; this translates into the diamond’s physical size.
We offer four pre-selected diamonds through our Co-Create digital experience ranging from 0.5 carat through to 1.5 carat in the below shapes. The physical size and proportions of a diamond are also dependent on its cut. We also offer a bespoke service beyond these sizes; please contact us for more information.
