Collection: Heart Cut Engagement Rings

A heart cut diamond is a diamond shape that is cut to resemble a heart. It is a unique and romantic shape, making it a popular choice for engagement rings and other sentimental jewellery.

The heart cut diamond is essentially a pear-shaped diamond with a cleft at the top that creates the distinctive heart shape. It has 58 facets, similar to a Round Brilliant cut diamond, which allows for excellent light reflection and sparkle.

When choosing a heart cut diamond, there are several factors to consider. The symmetry of the diamond is crucial, as a well-cut Heart shape will have evenly rounded lobes and a distinct cleft at the top. Look for a diamond with a well-defined and proportionate shape.

Overall, a heart cut diamond offers a romantic and symbolic look that is perfect for a cherished and sentimental moment. It is a unique choice that can symbolise love and commitment, making it a meaningful option for engagement rings or other jewellery pieces.

The ideal length-to-width ratio for Heart cut diamonds is typically between 0.90 to 1.10, with a ratio of 1.00 being considered perfect. This means that the length of the diamond should be approximately 1.00 times the width of the diamond.

However, the length-to-width ratio is ultimately a matter of personal preference. Some individuals may prefer a more elongated heart shape, while others may prefer a wider and more symmetrical heart shape.

It is important to note that the overall appearance of a heart cut diamond is not solely determined by the length-to-width ratio. Other factors such as symmetry, cut quality, and the proportions of the diamond's facets can also greatly affect its beauty and sparkle.

In addition to the general characteristics found on a diamond certificate, such as the 4 Cs (carat weight, colour, clarity, and cut), there are a few specific elements to look for on the certificate of a heart shape diamond:

1. Cut grade: The certificate should indicate the cut grade of the heart shaped diamond. Look for a grade of Excellent or Very Good, as this ensures optimal symmetry and proportion. 

2. Length-to-width ratio: The certificate should provide the length and width measurements of the diamond and indicate the length-to-width ratio. For a well-proportioned heart shape, the ratio should typically fall between 0.90 and 1.10, with a slightly elongated shape being preferred over a more squat or rounded shape. The heart shape should also have a well-defined cleft or point at the bottom. Additionally, the diamond should have excellent symmetry and polish to ensure maximum brilliance and fire.

3. Symmetry: The certificate should mention the symmetry grade of the heart shaped diamond. A higher symmetry grade indicates better alignment and balance in the shape of the heart.

4. Bowtie effect: The bowtie effect is a dark shadow in the centre of the diamond that resembles a bowtie. It is a common occurrence in heart shaped diamonds. The certificate should provide information on the intensity of the bowtie effect, as it can affect the overall appearance of the diamond.

5. Additional measurements and proportions: The certificate should include additional measurements such as total depth percentage, table percentage, pavilion angle, and crown angle. These measurements can give you a better understanding of the diamond's overall proportions and how it reflects light.

Yes, heart cut diamonds can have a bow tie effect and are not recommended as the bow tie effect refers to a dark shadow or area that appears in the centre of some diamond cuts, including the heart cut. It is caused by light leakage or poor reflection within the diamond, resulting in a loss of brilliance.  A well cut heart shape diamond will have minimal or subtle bow tie effect, with the facets and proportions carefully optimised to minimise its appearance. On the other hand, a poorly cut heart shaped diamond may have a more pronounced and prominent bow tie effect, which can negatively impact its overall beauty and brilliance.

When it comes to finding the best ring style for a heart shape diamond, there are a few considerations to keep in mind:

1. Solitaire Setting: A solitaire setting can be an excellent choice for showcasing the unique shape of a heart diamond. This minimalist style allows the diamond to be the centre of attention, highlighting its romantic and distinctive shape.

2. Three-Stone Setting: A three-stone setting, with two smaller side stones or other gemstones flanking the Heart shape diamond, can create a beautiful and symbolic design. This style adds extra sparkle and visual interest to the ring.

3. Halo Setting: A halo setting consists of a ring of smaller diamonds or gemstones surrounding the centre diamond. This setting can enhance the size and impact of a heart shape diamond, making it appear larger and more radiant.

4. Split Shank Setting: A split shank setting features a band that splits into two or more strands as it approaches the centre stone. This style can add an elegant and modern touch to a heart shaped diamond ring, creating a unique and contemporary look.

5. Side Stone Setting: A side stone setting involves smaller diamonds or gemstones set along the band of the ring, complementing and accentuating the heart shape diamond. This style can add extra sparkle and glamour to the overall design.

6. Vintage Setting: A vintage-inspired setting, such as a filigree or milgrain design, can add a touch of timeless elegance to a heart shape diamond ring. This style can be perfect for those who appreciate vintage or antique aesthetics.

Ultimately, the best ring style for a heart shaped diamond is a matter of personal preference and style. It's important to consider your individual taste, as well as the overall aesthetic and design that you desire for the ring.
