Diamonds are admired for their brilliance, durability, and timeless beauty. While colourless diamonds remain the most familiar choice, diamonds are available in many remarkable colours, shapes, and origins.
At The Boundless Legacy Jewels Inc. (TBLJ), we manufacture and offer jewellery featuring both natural and lab-grown diamonds. Understanding the differences between these options can help you select a diamond that suits your style, purpose, and budget.
Natural and Lab-Grown Diamonds
Before exploring diamond colours, it is important to understand the two primary origins available in fine jewellery.
Natural Diamonds
Natural diamonds develop deep within the Earth over billions of years under intense heat and pressure. Each diamond has its own characteristics, making every stone unique.
Lab-Grown Diamonds
Lab-grown diamonds are created using advanced technology that recreates the conditions under which natural diamonds form. They have essentially the same chemical, physical, and optical properties as natural diamonds.
Lab-grown diamonds are real diamonds—not imitations. They offer exceptional brilliance and often allow customers to select a larger or higher-quality stone within their preferred budget.
TBLJ clearly identifies whether a jewellery piece contains natural or lab-grown diamonds.
Popular Diamond Colours
Colourless and Near-Colourless Diamonds
Colourless diamonds are highly valued for their bright, clean appearance and ability to reflect light beautifully. The GIA colour scale grades these diamonds from D to Z, with D representing the highest colourless grade.
Colourless and near-colourless diamonds are popular for engagement rings, earrings, necklaces, bracelets, and other timeless jewellery designs.
Champagne Diamonds
Champagne diamonds feature warm shades ranging from light golden brown to deeper cognac tones. Their rich, earthy appearance works especially well with yellow and rose gold.
These diamonds are an excellent choice for customers who prefer distinctive jewellery with warmth and character.
Yellow Diamonds
Yellow diamonds receive their colour primarily from nitrogen within their crystal structure. Their shades range from soft lemon yellow to rich canary yellow.
Diamonds with strong, attractive yellow colour may be classified as fancy-colour diamonds. They create a bold and luxurious appearance in rings, earrings, pendants, and custom jewellery.
Pink Diamonds
Natural pink diamonds are exceptionally rare and highly valuable. Their colour is generally connected to changes within the diamond’s crystal structure rather than the presence of a colouring element.
Lab-grown pink diamonds provide another beautiful option for clients who want this distinctive colour at a more accessible price.
Blue Diamonds
Blue diamonds are among the rarest fancy-colour diamonds. Natural blue diamonds usually receive their colour from trace amounts of boron.
Their shades may range from light blue to intense blue. Lab-grown blue diamonds are also available for customers looking for this striking appearance.
Green Diamonds
Natural green diamonds typically develop their colour through exposure to natural radiation within the Earth over a very long period. Their colour can range from pale mint to deeper green.
Because natural green diamonds are extremely rare, they should be evaluated by a reputable gemological laboratory whenever possible.
Grey Diamonds
Grey diamonds offer a sophisticated and contemporary appearance. Depending on their characteristics, they may display silver, charcoal, or slightly blue-toned shades.
Their neutral colour makes them suitable for modern engagement rings, fashion jewellery, and gender-neutral designs.
Diamond Simulants
Diamond simulants may resemble diamonds, but they do not have the same chemical structure or physical properties. Common examples include:
- Cubic zirconia
- Moissanite
- White sapphire
- Certain types of crystal or glass
Simulants are not natural or lab-grown diamonds and should always be clearly identified as alternative stones.
Understanding Type I and Type II Diamonds
Diamonds may also be scientifically classified according to the impurities found within their crystal structure.
- Type I diamonds contain measurable amounts of nitrogen and represent the majority of natural diamonds.
- Type II diamonds contain little or no detectable nitrogen. Some Type II diamonds are exceptionally colourless, while others may display blue, pink, brown, or other colours due to different structural characteristics or trace elements.
This scientific classification is different from the colour, shape, or origin descriptions commonly used when purchasing jewellery.
How to Select the Right Diamond
When comparing diamonds, consider the traditional 4Cs:
- Cut: Determines how effectively the diamond reflects light.
- Colour: Measures the presence or absence of colour.
- Clarity: Evaluates internal and external characteristics.
- Carat weight: Measures the diamond’s weight rather than its visible size.
You should also consider the diamond’s origin, shape, certification, setting, and how the finished jewellery will be worn.
