Choosing your diamond
You may have heard about the 'four C's' to consider when choosing your diamonds. They include the cut, colour, clarity and carats of the diamond. The quality of each of these dimensions determines the overall quality and value of the diamond. We are skilled in helping our customers find their perfect diamond to suit their preferences. We also believe that certification, design of the jewellery piece, and ethics of the diamonds are important considerations.
Cut refers to both the shape and the quality of the facet style of the diamond.
Diamonds come in a vast array of shapes, including round brilliant, emerald cut, heart shaped, oval, pear, marquise, cushion, princess square cuts, baguettes and more.
The quality of the cut determines the light performance of the diamond, that is, how much is sparkles!
The proportions of the diamond determine the light performance. An ideal cut yields the highest light return. Also to be considered are symmetry and finish.
The quality of the cut has a great influence on the value of a diamond. Superior cuts take more time, greater skill and yield lower finished weights, adding to the overall value.
We prefer to use only diamonds classed from 'very good' to 'triple excellent' cuts.
Colour ranges from totally colourless through a progression of tinted and lighter colours to fully saturated 'fancy colours', which are themselves priced for their colour.
G-J near colourless
K-M faint yellow
N-R very light yellow
S to Z light yellow
Z + fancy yellow
Clarity of a diamond refers to its optical quality. Grading depends on the size, number and position of internal or external flaws or imperfections. Most of our diamonds fall in the VS1 to P range.
FL totally flawless at x10 magnification
IF internally flawless at x10 magnification
VVS1, VVS2 very very small inclusions, very difficult to see at x 10 magnification
VS1, VS2 Very small inclusions, difficult to see at x 10 magnification
SI1, 2 small inclusions, easily seen at x 10 magnification
P1, 2, 3 pique or imperfect inclusions, visible without magnification
'Carat' comes from the ancient Greek name for the Carob seed, which had a very consistent size and weight, and was once used as a counterweight for weighing diamonds and gemstones. The metric carat is the international standard unit of weight for diamonds and gemstones.
1 carat = 0.2 gram
The carat is further divided into points
1 carat = 100 points
Many of our larger and higher quality diamonds come with certification from the Gemological Institute of America. If you are having a diamond piece made to order, we can choose a diamond that has this certification. Once a diamond has already been set in a piece, it can not be submitted for certification.
Many of our pieces come with independent valuations which can be used for your insurance. If the piece you are interested in does not have a valuation, we can have one arranged for you. We can also have valuations done for jewellery pieces you already own.
We specialise in designing jewellery made to order. If you can imagine it, we will do our very best to make it!
We are very happy to help guide you through the design process.

We are members of the Jewellers Association of Australia and signatories to their code of conduct. We have also made the a public pledge in joining the campaign for ethical jewellery. And perhaps the best evidence that we care about the ethics behind what we do, is that we have taken the time to write about it here.
We would be happy to hear from you with any queries in choosing your jewellery.
