FAQs About Natural Diamond Engagement Rings

Why choose a natural diamond engagement ring over other options?

Natural diamond engagement rings have a timeless appeal, symbolising enduring love and commitment. Formed over millions of years under intense heat and pressure deep within the Earth, each natural diamond is unique, making your ring truly one-of-a-kind. Diamonds are also renowned for their unmatched brilliance, with a sparkle that has made them the traditional choice for engagement rings. Their clarity and ability to reflect light give natural diamonds a captivating, eye-catching quality. Many people are drawn to the romantic history of natural diamonds, as they represent a classic and enduring symbol of love. Additionally, natural diamonds tend to hold their value better over time compared to some alternative options, making them a meaningful investment in both sentiment and worth.

How do you ensure that a natural diamond is ethically sourced?

To ensure that a natural diamond is ethically sourced, look for diamonds that come with certification from organisations like the Kimberley Process or those that are classified as conflict-free. The Kimberley Process is an international certification scheme that aims to prevent conflict diamonds—diamonds that fund violence—from entering the global market. However, for greater peace of mind, many jewellers go beyond the Kimberley Process and offer diamonds that are sourced from countries known for ethical mining practices, such as Canada, Namibia, or Botswana. Canadian diamonds, for instance, come with specific certifications that verify their origin and ensure they were mined responsibly. Another option is to work with jewellers who offer transparency about their supply chains and focus on supporting local communities where mining takes place. By doing some research and asking the right questions, you can find a natural diamond that aligns with your ethical values.

Are natural diamond engagement rings durable for everyday wear?

Yes, natural diamond engagement rings are one of the most durable options available, making them ideal for everyday wear. Diamonds score a perfect 10 on the Mohs hardness scale, meaning they are the hardest natural material on Earth and are highly resistant to scratches. This hardness makes diamonds perfect for engagement rings, which are meant to be worn daily and endure the bumps and knocks of everyday life. However, while diamonds are incredibly hard, they can still be chipped or damaged if subjected to strong impact, so it’s a good idea to handle them with care. For added protection, you might consider a setting that shields the diamond, such as a bezel or halo setting. With regular cleaning and occasional professional check-ups, a natural diamond ring can maintain its stunning sparkle and durability for a lifetime.

How do the 4 Cs affect the quality of a natural diamond?

The 4 Cs—cut, colour, clarity, and carat weight—are the key factors that determine the quality and value of a natural diamond.

  • Cut: The cut of a diamond is perhaps the most critical factor, as it affects how well the diamond reflects light. A well-cut diamond will have the most brilliance and sparkle, regardless of its other characteristics.
  • Colour: Diamonds are graded from D (colourless) to Z (light yellow or brown). Colourless diamonds (grades D-F) are considered the most valuable, but near-colourless diamonds (grades G-J) can offer excellent value while still appearing white to the naked eye.
  • Clarity: Clarity measures the presence of internal flaws (inclusions) or external blemishes. A diamond with fewer inclusions and a higher clarity grade will generally have more brilliance, but many inclusions are microscopic and do not affect a diamond’s visual appeal.
  • Carat Weight: This refers to the size of the diamond. Larger carat weights typically mean higher prices, but two diamonds of the same carat weight can vary in value based on their cut, colour, and clarity. Balancing these factors according to your budget and preferences can help you find the perfect diamond for your engagement ring.

How should you care for a natural diamond engagement ring?

Caring for a natural diamond engagement ring ensures it stays as beautiful as the day you first wore it. To clean your diamond at home, soak it in a solution of warm water and a few drops of mild dish soap. Use a soft toothbrush to gently scrub the diamond and setting, especially underneath the stone where dirt can accumulate. Rinse the ring with clean water and dry it with a soft, lint-free cloth. Avoid using harsh chemicals or abrasive materials, as they can damage the metal of the ring’s setting. It’s also a good idea to remove your ring during activities like exercising, gardening, or cleaning to avoid knocks and exposure to chemicals. For the best results, take your ring to a professional jeweller for a deep clean and inspection once a year to ensure the diamond remains secure in its setting and continues to shine.

Are natural diamond engagement rings a good investment?

Natural diamond engagement rings can be considered a good investment in terms of both sentimental and financial value. While most diamonds do not appreciate significantly in value over time, they tend to hold their worth better than many alternative gemstones, especially if they are high-quality stones. The value of a diamond is influenced by factors like its carat weight, cut, clarity, and colour, as well as market trends. Investment-grade diamonds are typically rare, large, and of exceptional quality, but even standard engagement diamonds can maintain their value as family heirlooms or cherished personal items. If investment potential is a key concern, it’s wise to consult with a reputable jeweller who can guide you towards diamonds that are more likely to retain their value. Regardless of market factors, natural diamonds carry significant emotional value, symbolising lifelong commitment and creating lasting memories, which is often the most important aspect of the investment for many couples.
