What Color grade should I buy?
Color Grade starts from D and then lowest goes upto P but normally from D to M. Never spend on higher color grades as diamond prices go steeply high as you go for higher color grades without adding comparable value to the diamond(see Rapaport Price List). You can comfortably start with IGI certified K color which is reasonably good white faceup when set in the ring. After this going for higher Color grades depends upon your budget and your capacity to spend.
What Clarity grade should I buy?
Clarity grades start from FL to I3. You can start with IGI certified Si1 which must be either 100% Eyeclean and not too many Inclusions/Spots in the centre or atleast 80-90% eyeclean. If your budget higher, first go for higher clarity grade than going for higher color grade.
What Cut grade should I buy?
Your first priority should be to buy a Triple Excellent Cut diamond meaning Cut: Excellent, Polish: Excellent and Symmetry: Excellent. This provides best luster and fire in a diamond.
What Fluroscent grade should I buy?
This is the parameter which is highly misunderstood or people are highly misguided. You can save a lot of money on this. For color grades K and below and clarity Si1 and below and weak VS2, go for None fluroscence only. For color grades K and below and clarity good vs2 and above you can go upto even STRONG fluroscence if there is no internal graining in the centre of the diamond. This will save you a lot of money besides giving your diamond a whiter faceup and no effect on luster and fire. Internal graining not visible even with magnifying lens. If there is strong internal graining in the centre of a diamond, it will make it hazy. For color grades J and I and clarity good vs2 and above you can go upto SLIGHT fluroscence if there is no internal graining in the centre of the diamond. For color grades H and above and clarity good vs2 and above you must go only for NONE fluroscence.
