10 Gemstone Shapes for Diamonds

Gemstone shapes are like expressions of love, each one unique and beautiful in its own way. Unique, classic, bold, and elegant are some of the few ways certain gemstone shapes can make you feel. Here are 10 popular gemstone shapes to consider for your jewelry piece:


The round shape is a timeless and classic symbol of love and romance. Its perfectly symmetrical shape represents the eternal bond between two individuals, with no beginning and no end. 

 The round diamond's brilliance and sparkle captures the light and reflects it back in a dazzling display of fire and radiance. When set in an engagement ring, the round diamond represents a promise of everlasting love and commitment, a reminder of the depth of emotion between two people. 

Its versatile shape makes it a popular choice for a variety of styles and settings, from simple and elegant solitaires to more intricate and unique designs. With its stunning beauty and enduring symbolism, the round diamond is the ultimate expression of love and romance.

Due to their deep pavilion, round gemstones can appear smaller than other shapes of the same carat weight, but it does not diminish in value and is a shape always coveted in the jewelry world.


An oval-shaped diamond exudes a sense of timeless romance and elegance. Its elongated shape creates a flattering silhouette on the finger, giving the appearance of longer, slender fingers

The oval shape also has a classic feel that adds to its romantic charm. When set in a minimalist design, it can evoke a sense of understated luxury and sophistication. The oval also maximizes the diamond's brilliance and fire; as brilliant as its round counterpart, having the same number of facets.

This makes it a perfect choice for engagement rings or romantic jewelry pieces that capture the beauty and sentiment of a special moment. Overall, the oval-shaped diamond embodies a sense of refined, timeless romance that is sure to take your breath away.

Some oval-shaped stones may exhibit a "bow-tie" effect, which is a dark or shadowy area in the center of the stone caused by the way it is cut, detracting from the overall appearance. 

Additionally, oval-shaped gemstones can vary in length-to-width ratio, which can affect the overall appearance of the stone, and some people may prefer a longer, more elongated oval shape, while others may prefer a more rounded shape.



The pear-shaped is a stunning choice for engagement rings and other jewelry. With its unique shape, it is often described as a teardrop or a drop of dew, adding to its ethereal and delicate beauty. 

The rounded bottom of the pear shape gently tapers into a point, giving the diamond a graceful and elegant appearance that is both sophisticated and timeless. The elongated shape of the pear can also make the finger appear slimmer and more delicate. 

As the light dances across the facets of the pear-shaped diamond, it creates a mesmerizing and dazzling sparkle that captures the eye and the heart. Whether set in a classic solitaire or a more intricate design, a pear-shaped diamond is sure to evoke feelings of romance and enchantment.

It can be challenging to find a matching pair of pear-shaped gems for earrings or other types of jewelry, as each stone's shape can vary significantly. Though, a perfect pear-shaped gemstone is truly a beauty to behold.


The marquise shape is a symbol of elegance and sophistication, with its unique pointed oval shape that evokes a sense of timeless beauty. Its elongated form represents the infinity of love, as well as the promise of a future together. 

It is perfect for the romantic at heart, as its dramatic appearance captures attention and admiration. When paired with other diamonds or set in a delicate band, the marquise diamond can add a touch of glamor and luxury to any engagement ring or piece of jewelry. 

It is a unique and striking choice for those who want to express their love in a bold and unforgettable way.

Their less common shape makes them an eye-catching option, and yet borrows its shape from one of nature’s beautiful patterns: leaves – shaped for a love ever-growing.

They are also known for having the largest carat face. A 1.0ct marquise stone will appear larger than a 1.0 round stone due to their cut.


The step-cut facets of the emerald shape give it a timeless elegance that is highly sought after. Emerald-shaped gemstones are versatile and can be used in various styles of jewelry. The transparency of the flat facets also showcases the clarity of the gem, making it the perfect cut for higher quality stones. 

The limited sparkle of emerald-shaped stones may be a downside for those looking for more eye-catching shine and fire in their gems. Inclusions and blemishes may also be more visible in emerald-shaped stones. 

Though with the right quality gemstone, the emerald-cut is magnetizing for such a unique shape, drawing people to look into the perfection of your ring. 


This fancy shape is the perfect embodiment of timeless elegance and romantic allure. With its soft and rounded edges, the cushion shape exudes a sense of warmth and charm that captures the heart. 

They are typically cut with a large number of facets, which can maximize the stone's brilliance and sparkle. This cut also hides inclusions or blemishes within the stone's facets, making it a good choice for gemstones of SI1 clarity and above. 

The large number of facets on this shape of diamond creates a spectacular play of light, enhancing its brilliance and fire. The cushion diamond is a classic choice that exudes grace and sophistication, perfect for those who appreciate timeless aesthetics. 

Their elongated counterparts offer the same soft warmth with the edge of elongating your finger. Think, a cross between emeralds and rounds creating a shape with the best of both worlds.  


A heart-shaped diamond is the perfect symbol of love, with its unique and instantly recognizable shape capturing the essence of romance. Its elegant curves make it a striking yet tender choice for any piece of jewelry, especially for engagement rings. 

The elongated point of the heart shape can make the diamond appear larger and more dramatic, adding to its allure. The way that the two halves of the heart come together perfectly also symbolizes the union of two people in love. 

When a heart-shaped diamond is given as a gift, it expresses a deep and powerful emotion that can be felt for a lifetime. Whether it's a first love or a long-lasting commitment, a heart-shaped diamond is a beautiful and sentimental way to celebrate the beauty of true love.
