Round Brilliant
1. Traditional yet most popular, perfect for engagement rings.
2. Over 75% of diamonds sold today are Round Brilliant.
3. Goes very well with either as a solitaire or with accent stones.
4. Standardized through a precise formula to achieve the maximum in fire and brilliance.
Princess Cut

2. Requires more weight to be directed toward the diamond's depth in order to maximize brilliance from
    a square cut.
3. Depth percentages of 70% to 78% are common.
Emerald Cut
1. Tends to be less fiery than a "round brilliant" cut, but it also tends to have broader, more dramatic
    flashes of light.
2. Known as a step cut because its concentric broad, flat planes resemble stair steps; a rectangular
    shape with cut corners.
3. Inclusions and inferior colour can be more pronounced in this particular cut.

Marquise Cut

    diamond to match it.

    the effect of its colour refraction.
2. Shape of the less fiery Emerald Cut.

    cleft at the top).
2. Is considered by some to be the most romantic of all diamond cuts.
3. Requires extraordinary skill of the cutter determines the beauty of this cut.

The 4 C’s

Every diamond is unique, there are no two diamonds are identical. GIA created the first, and now globally accepted standard for describing diamonds, they are graded by: Color, Clarity, Cut, and Carat Weight. Today, the 4Cs of Diamond Quality is the universal method for assessing the quality of any diamond, anywhere in the world.


1. Colour refers to a diamond's lack of colour, grading the whiteness of a diamond.
2. A colour grade of D is the highest possible, while Z is the lowest.


1. Clarity refers to the purity of a diamond.
2. Clarity is a measure of the number and size of the tiny imperfections that occur in almost all diamonds.
3. Many of these imperfections are microscopic, and do not affect a diamond's beauty in any visible way.


1. Cut is a diamond's most important characteristic as the cut determines a diamond's shape and brilliance.
2. It has the greatest overall influence on a diamond's beauty.
3. It determines what we generally think of as sparkle.


1. Carat is specifically a measure of a diamond's weight, and by itself may not accurately reflect a diamond's size.
2. We tend to evaluate diamond size by viewing it from the top because that is how diamonds are presented to us
    when set into a ring.
3. To understand diamond size, carat weight should be considered in conjunction with two other criteria:
    A. Distance in millimetres across the top of the diamond.
    B. Diamond's cut grade.


A certificate describes the quality of a diamond, but it does not place a monetary value on the gem. Before purchasing a diamond, you should expect to review a copy of its certificate as proof that it has undergone an unbiased, professional examination.

There is no physical difference between a diamond that is certified and one that is not. The difference between a certified and an uncertified diamond is that; with the certified diamond, you have tangible, legal assurances as to the particular nature and quality of the diamond you are purchasing.

A certified diamond comes with a diamond grading report guaranteed by an accredited gem lab. This report assures customers that the diamond is independently recognized as possessing all the qualities specified by that report. When you purchase a certified diamond, you are getting a diamond with beauty and pedigree.

On the other hand, an uncertified diamond is not accompanied by a diamond grading report, and therefore its stated quality is only based on the word of the seller. An uncertified diamond is not necessarily a bad diamond; certainly, it can be as beautiful as its certified counterpart. However, regardless of certified or uncertified diamonds, we encourage our customers to always buy from trusted and well-established jewellers.

All the certified diamonds featured in Diamond2u.com are by GIA. For uncertified diamonds, Diamond2u is providing quality assurance with buy back policy and we offer a lifetime warranty.

Diamond Florescence

Referring to the diamonds that have the tendency to release a soft coloured glow when subjected to ultraviolet light (such as a "black light"). In the diamond industry, the existence of fluorescence in a diamond which is caused by the natural mineral properties of the diamond, has caused many debates and has influenced the pricing of diamonds. For the average observer fluorescence made no difference and experienced observers (diamond graders and trade professional) did not agree on the influence of fluorescence. And differing to previous theories, the experienced or trained observers most consistently determined that diamonds with strong fluorescence were the ones with the best colour.

So do not let fluorescence excessively influence your choice when selecting a diamond. Of course, if you are buying diamonds as an investment and intend resale, you would want to pay attention to how the industry prices diamonds with fluorescence, independent of whether the price difference is justified.
