I love rocks :p Only diamonds, because they fascinate me and chicks dig em... And being South African and having a father who is good mates with polishers it don't help. Anyhow loads of people always question me on some stuff so here is most of what you need to know.
Clarity
| FL,IF | Flawless, Internally Flawless: No internal or external flaws. Internally Flawless: No internal flaws. Very rare and beautiful diamonds. |
| VVS1,VVS2 | Very, Very Slightly Included: Very difficult to see inclusions under 10x magnification. An excellent quality diamond. |
| VS1,VS2 | Very Slightly Included: Inclusions are not typically visible to the unaided eye. Less expensive than the VVS1 or VVS2 grades. |
| SI1,SI2 | Slightly Included: Inclusions are visible under 10x magnification, and may be visible with the unaided eye. A good diamond value. |
| I1, I2, I3 | Included: Blue Nile does not carry diamonds of I-grade clarity. |
Colour
| D | Absolutely colourless. The highest colour grade, which is extremely rare. |
| E | Colourless. Only minute traces of colour can be detected by an expert gemmologist. A rare diamond. |
| F | Colourless. Slight colour detected by an expert gemmologist, but still considered a "colourless" grade. A high-quality diamond. |
| G-H | Near-colourless. Colour noticeable when compared to diamonds of better grades, but these grades offer excellent value. |
| I-J | Near-colourless. Colour slightly detectable. An excellent value. |
| K-M | Noticeable colour. Not carried by Blue Nile. |
