About Heart Shape Ratio

The beauty of a heart-shaped diamond lies in its proportions, with the length-to-width ratio being the key. A 0.95 ratio offers a more rounded heart shape, while a 1.05 ratio presents a narrower, longer shape. The standard ratio of 1.00 is the most balanced and closest to a perfect heart shape. Although there is no official cut grade for heart-shaped diamonds, it is important to consider personal preference and the overall harmony of the diamond. The cut grade reference chart below will assist you in selecting your ideal heart shaped diamond.

About Heart-shaped Diamond Colour

The colour grading of diamonds ranges from D (completely colourless, the highest grade) to Z (light yellow). Diamonds graded D to F are considered colourless, while those graded G to J are nearly colourless, with the colour becoming increasingly noticeable as you move down the scale. Generally, the closer a diamond is to being colourless, the more valuable it is, though certain colour grades, like light yellow, can have their own unique appeal.

Heart-shaped Diamond Clarity

Clarity refers to a diamond's degree of internal and surface imperfections (known as inclusions and blemishes). Clarity grades range from Flawless (FL/IF) to Included (I1-I3). Diamonds with higher clarity grades have fewer imperfections, making them rarer and more expensive, while diamonds with lower clarity grades have more noticeable flaws, but can still display beautiful brilliance in certain cases.

FAQ

About Heart Shaped Lab Grown Diamonds

The cut quality of heart-shaped diamonds is primarily assessed based on symmetry, proportions, and polish. A high-quality heart-shaped diamond should exhibit a balanced and symmetrical heart outline, which is especially noticeable in diamonds of 0.5 carats and above, where the iconic heart shape is more pronounced.

 

The ideal length-to-width ratio typically ranges between 0.95 and 1.05 to ensure the diamond is neither too elongated nor too rounded. The quality of the polish is crucial for the smoothness of the diamond's surface, directly influencing its brilliance and sparkle. Overall, precise cutting, proper proportions, and meticulous polishing are key factors that contribute to the beauty and allure of heart-shaped diamonds.

How to Evaluate the Cut Quality of Heart-Shaped Diamonds? What Factors Affect Their Brilliance and Sparkle?

When selecting a heart-shaped diamond, colour and clarity grades are crucial considerations. Due to the unique shape of heart-shaped diamonds, colour can be more noticeable at the pointed end. It is advisable to choose a higher colour grade (G-H or higher) to ensure uniformity and aesthetic appeal. For clarity, the distinctive structure of heart-shaped cuts can make inclusions more visible. Therefore, opting for diamonds with a clarity grade of VS or higher will help ensure the diamond's appearance remains flawless. Overall, high-quality colour and clarity grades are essential to accentuate the beauty of heart-shaped diamonds.

How to Choose Colour and Clarity Grades for Heart-Shaped Diamonds

To authenticate lab-grown diamonds, you should first rely on professional certifications such as those from GIA (Gemological Institute of America) or IGI (International Gemological Institute). Lab created diamonds share the same chemical and physical properties as natural diamonds, but specialised instruments like spectrometers can detect subtle differences by examining internal structure patterns or using ultraviolet light. Additionally, lab-grown diamonds often have specific marks, such as laser inscriptions, to confirm their identity. Choosing reputable suppliers and requesting certification reports during purchase are crucial steps in verifying the authenticity of lab-grown diamonds.

How to Authenticate Lab-Grown Diamonds?

Lab-grown diamonds often surpass natural diamonds in quality. This is because the production process in a laboratory under precisely controlled conditions can significantly reduce the inclusion of impurities, ensuring the diamonds' purity and colour consistency. Unlike natural diamonds that take billions of years to form deep within the Earth and may contain natural flaws, lab-grown diamonds benefit from this controlled environment, often resulting in higher clarity and better cut quality. Consequently, lab created diamonds can offer superior options in terms of visual appeal and technical characteristics compared to traditional natural diamonds.

Can lab-grown diamonds compare in quality to natural diamonds?

Lab-grown diamonds are synthetic diamonds created under laboratory conditions. This process mimics the natural conditions under which diamonds are formed within the Earth and is primarily achieved using High-Temperature High-Pressure (HTHP) or Chemical Vapor Deposition (CVD) techniques. 

 

HTHP: In this method, carbon elements are subjected to high temperatures and pressures that simulate the Earth's crust conditions, transforming the carbon into diamonds.

 

CVD: This method involves decomposing carbon source gases in a gas mixture and depositing the carbon onto a specific substrate to grow the diamond.

 

Both techniques produce lab diamonds with the same structure and optical properties as natural diamonds, offering high-quality and affordable options.

How are lab-grown diamonds made?

Lab-grown diamonds, also known as synthetic or lab-created diamonds, are gemstones scientifically synthesised under controlled conditions to have the same chemical structure and physical properties as natural diamonds. Unlike natural diamonds, which are formed over billions of years deep within the Earth, lab-grown diamonds are produced much faster and more environmentally friendly. The production process is also more cost-effective and ensures the diamonds are conflict-free. While visually and structurally indistinguishable from natural diamonds, lab diamonds offer a more sustainable and economical alternative.
