The heart shaped diamond is easily the most romantic shape option, hence a popular shape, especially around Valentine’s Day. To ensure diamond brilliance the lobes must be totally symmetrical, so forming this shape accurately can be difficult.

The heart shape diamond is quite similar to the pear shape. It often begins as a pear shape that has an inclusion within the rounded end. The portion with the inclusion is removed, thus creating the heart shape.

It is essential that the heart shaped diamond must have a highly skilled cutter to insure that the distinctive lobes are balanced, smooth, and well defined, all the while retaining a brilliant shine.

Emerald Cut

The emerald cut with its long lean lines is a rectangular shaped diamond which has a relatively larger open table (top, flat surface) and fewer facets, highlights the clarity of the diamond more than any other shape, hence an unmatched elegance that a brilliant will not possess.

The emerald shaped Diamond is similar outwardly to the radiant, but vastly different in that it is a step cut diamond (like the asscher cut and baguette cut). This was originally the accepted way for the emerald gemstone to be cut and subsequently adopted for cutting diamonds, hence the name – Emerald Shape.

The emerald cut, beautiful and precise, gives the emerald shape a timeless, elegant  look, differing to the modern sparkle of other Brilliant diamond shapes. It makes up for the lack of brilliance by the crystal clarity of its vast, open table. This makes it important that it should maintain a higher quality of color and clarity.


Asscher Cut

Asscher Cut

The asscher cut is an octagonal shape with its mirror like tendencies, the asscher is bright, shiny and clear.

This diamond shape is almost identical to the emerald shape, but square with cropped corners rather than rectangular.

The baguette cut is most often used as a side stone.  Similar to the Emerald cut but with different facets and with pointed corners, it usually comes in smaller weights.

The cushion shape is like a square where the sides and corners have been rounded out, and has larger facets to increase the stone’s brilliance. It may be described as a softer emerald shape.

The cushion shape is a hybrid of the old miner cut and the more modern cuts, sometimes brilliant cut or step cut. The old Miner and European cuts are no longer used, as they were present before the fine-tuning of today’s modern round brilliant and cushion shapes.

Typically recognized as an antique shape, the cushion cut has been popular for more than a century and always elegant. At one point it lost its popularity but with new technology in cutting, it is becoming a trendy shape, modern yet traditional.  It shows good light performance and  brilliance under low lighting.


Princess Cut

Princess Cut

The princess cut is the second most popular shape, a square or rectangular diamond shape with an array of intricate facets that increase the diamond’s inherent sparkle. Cut for maximum light reflection, this stone looks at home in almost any setting and is a beautiful variation of the standard round cut without losing the diamond look.

The princess cut shape is very popular with diamond cutters because more of the rough diamond can be used, that means less wastage and a cheaper price per carat weight. It suits people with a taste for symmetry and more contemporary style

The most sought after Princess Diamonds are completely square, while variations of the princess stone are longer on the sides, more rectangular and usually less valuable.


Radiant Cut

Radiant Cut

The radiant can be either square or rectangular diamond shape (as is the princess) but with angled, cut off edges, a combination of the round brilliance cut with the elegance of the emerald cut.

Its trimmed corners are the signature characteristic of this shape.

Radiant cut diamonds tend to make any color in the diamond look brighter, this is great for color diamonds but not so good for colorless diamonds.


Cuts Of Diamonds For Engagement Rings

There are many different cuts of diamonds for engagement rings. The way a diamond is cut will have the biggest effect on how the diamond catches and interacts with light. While high grades of color, clarity, and carat weight also contribute to a diamond’s appeal, it’s the cut that determines the symmetry of the stone’s facets, its overall proportions, and its ability to reflect light.

An expertly cut diamond will achieve high levels of brilliance, sparkle, and durability. Even if a diamond is graded well in other areas, a poor cut can result in a dull, muted effect. A diamond’s cut is the most critical of the 4 c’s of diamonds, it’s what gives the diamond its brilliance, sparkle, and fire, the diamond’s three main attributes.

If the diamond is too shallow and not cut right, some of the light will be lost out of the bottom. A diamond that is cut too deeply will lose light out the side of its base. An ideal cut diamond will reflect most of the light through their table or top surface.

Round Cut Diamond Engagement Rings

While there are many different cuts of diamonds and different diamond shapes for engagement rings, many are set with princess cut diamonds, but the majority are set with a round cut diamond, and the traditional shape, a round brilliant diamond.

An Ideal cut has a specific set of guidelines defining the proportions that give a diamond the highest level of fire and brilliance. It takes into account the relationship between the table size, crown angle, pavilion angle, girdle, crown depth and pavilion depth. It evaluates the following:

-The size of the table (flat surface) relative to the stone’s width at its widest point, called the girdle.
-The angles of all facets relative to one another.
-The depth of the crown vs. the pavilion and how well the facets at the crown (top) align with the pavilion (bottom).
