Ever since http://www.diaprices.in stopped publishing prices in the old format I mentioned before and switched to the current one with no details of smaller stones and better colour grades I have found the price list here of more use to figure out what sort of deals I am being offered on my diamonds.Hope you find it useful too.

The beauty of a diamond depends more on cut than any other factor. Diamond cut has three primary effects on appearance: brilliance (the brightness created by the combination of all the white light reflections from the surface and the inside of a polished diamond), fire (the dispersion of light into the colors of the visible spectrum, seen as flashes of color), and scintillation (the flashes of light and dark, or sparkle, when a diamond or light source is moved).
When a diamond is fashioned from a rough stone, the cutter must balance optimal cut (and therefore appearance) against maximum yield (cutting the diamond to maintain as much carat weight from the rough stone as possible). Because many customers are willing to pay more for a larger, fair-cut cut diamond than for a slightly smaller, well-cut diamond, there is pressure on the cutter to sacrifice appearance for weight. This is why the cut is so important.
For the larger and more expensive diamonds dealers will be willing to provide more detailed grading reports with diagrams ,as above,showing proportions of the diamond.Use the tables below to ensure you are getting the best value for money. Read more of this post

The round cut diamond is the most popular diamond shape, representing approximately 75% of all diamonds sold. Due to the mechanics of its shape, the round diamond is generally superior to fancy diamond shapes at the proper reflection of light, maximizing potential brightness.
Virtually all round diamonds are brilliant-cut, meaning they have 58 facets (57 when there is no culet).
Round diamonds cost more on a per carat basis than fancy shapes for two reasons; the demand for round diamonds is very high, and the yield is relatively low. Because more of the rough stone is lost in the cutting of a round diamond, the cost of each carat retained is higher. A typical round diamond (for example; a 1.00 carat, F-colour, VS2-clarity, Ex cut) may cost 25-35% more than a similar fancy shape.
The colour chart below provides a general guide for evaluating color in round diamonds. Read more of this post

The vast majority of untrained observers (and many gemologists) cannot distinguish a colour grade from the one just above or below unless the diamonds are compared side by side in a controlled environment. Even when side-by-side, changes in colour are difficult to detect in I colour and higher diamonds.
Colour becomes much harder to detect once a diamond is set in a ring and placed in an environment that contains colour (as opposed to the all white background used in colour grading). For instance, a H colour diamond may look as colourless as a D when set in a ring under normal lighting conditions, especially if the two are not compared side by side.
For the best value in what would appear to the naked eye as a colourless diamond, look for G-J diamonds. Because colour is easier to detect in larger diamonds (just as a large carafe of white wine shows more colour than a small glass), opt for G-H in diamonds over 1 carat, and I-J for those under 1 carat. Once set in a ring, these diamonds will look just like higher colour grade diamonds. Instead of investing in higher color, invest in higher cut, the most important factor in a diamond’s brilliance.
