Top best answers to the question «What is the highest grade a diamond can be»

  • D, the highest grade, is reserved for diamonds that do not show any color, even when viewed under bright lighting and magnification. S through Z, on the other hand, are the lowest grades, and is typically used for diamonds that display an obvious, clearly visible yellow or brown tint.

A 'D' grade for a diamond refers to its colour. This grade is the highest jewelry grade of diamond, and it means that the stone lacks significant nitrogen, which gives a diamond a yellow colour.

So, What is the Best Diamond Clarity Rating For Your Purchase? It depends on what you are looking for. If you are on a budget and want to get the biggest bang for your money, the best diamond clarity grade for you is VS2 or SI1. As long as you have eyeballed the diamond and it is eyeclean, there’s really nothing to be worried about.

In the letter-grade diamond color scale, D (colorless) is the highest and best grade, and Z is the lowest. Diamond used to be graded like gemstones on a range that included AAA, AA, A, and B, so the new scale started at D to avoid confusion. This color chart shows how the color of a diamond changes visually across the scale.

GIA created the 4Cs (Color, Clarity, Cut and Carat Weight) as a universal method for establishing the quality of any diamond, anywhere in the world. The 4Cs means two very important things: diamond quality can be communicated in a universal language, and diamond-buying consumers can know exactly what they are about to purchase.

And when it comes to prices in the trade, clarity has just as much impact on prices as colour. So that 4 carat G graded Diamond I mentioned earlier, which was $47,000 per carat if it was IF graded (so the second highest grade), would be $6,600 per carat if it was I1 graded. What Difference Does This Make?

The D color grade is the highest quality color grade a diamond can receive, and can reasonably be called the “best color” for a diamond. However, it’s a little more complicated than that. While a D color diamond is undoubtedly the best in terms of color, the difference in price between a D color diamond and a diamond with a lower color grade but near identical appearance can often be huge.

The highest grade for diamond color is D, or completely colorless. But these ratings are determined by expert gemologists comparing against a set of master stones. The naked eye won't be able to detect the slight tint of yellow in a set diamond several grades lower. For sheer value, we recommend a diamond in the G through I range.

When determining the clarity of diamonds, experts will note the appearance of the diamond when it is face up, with a microscope at 10x magnification and eye visibility. However, to identify any diamond inclusions there may be, a higher power than 10x will be used. Otherwise, it may be too difficult to determine.

Diamonds are graded according to cut, colour, clarity and carat weight. When cutting a rough diamond stone, the diamond cutter first determines the natural colour of the stone, then plans a cut that preserves the highest carat weight for its maximum clarity. So the highest grade of diamond is the largest stone with zero flaws in the rarest colour with the most perfect cut for that stone. These diamonds are sold at auction and bring millions of dollars to sellers. In jewelry, the D colour is the highest grade colour; internally flawless is the highest clarity, blue and red could be the rarest natural colours. The Gemological Institute of America's Web site will help you better understand the four Cs, below. Finally, exceptional stones, are also graded according to the type of diamond, the most common being Type I. Read more about diamond types, below.
