Education and my ring size

"A Diamond Education" – The 4C'S

Carat Wight

The weight of a diamond is measured in carats.  One carat is equal to 1/5th of a gram.  A gram is also split into points.  100 points = 1 carat.
For example:

 Carat Size = Millimetre Width
0.05 Carat  =  2.5 mm

0.10 Carat  =  3.0 mm

0.15 Carat  =  3.4 mm

0.20 Carat  =  3.8 mm

0.25 Carat  =  4.1 mm

0.40 Carat  =  4.8 mm

0.50 Carat  =  5.2 mm

0.65 Carat  =  5.9 mm

0.75 Carat  =  5.9 mm

1.00 Carat  =  6.5 mm
1.50 Carat  =  7.4 mm

2.00 Carat  =  8.2 mm

Cut

This is the actual shape of the diamond.  An example of this is a Princess cut diamond.

Colour

Diamonds are graded using a scale that ranges from "D" to "Z".  Colorless or near white diamonds are classified "D" to "K".  At Vertigo Diamonds we only use "D" to "K" diamonds.

Clarity

Most diamonds have imperfections, which are graded on a scale from IF – I3. At Vertigo Diamonds we only use diamonds between IF – SI3.
