Why are customers preferring lab diamonds in London?

There are several compelling reasons why numerous people in London prefer man made diamonds over mined ones:

  1. PRICE - Lab created diamonds offer the dream diamond ring at a much more affordable price, ensuring you don't overspend.
  2. IDENTICAL APPEARANCE - Lab grown diamonds and mined diamonds are indistinguishable, sharing the same physical, chemical, and optical properties.
  3. ETHICAL SOURCING - Our lab grown diamonds in London are ethically sourced, ensuring no environmental harm during their creation. They are eco-friendly and conflict-free.
  4. GENUINENESS - It's critically important to be cautious of imitations in the diamond market. Some sellers use misleading terms like 'synthetic diamonds London', 'round brilliant', 'artificial', 'moissanite', 'cubic zirconia', 'crystals', and 'diamond simulants' to sell non-diamond materials. However, those are simply not natural diamonds or lab diamonds. It's essential to research, read reviews, and verify the authenticity of your diamond, especially for something as significant as an engagement ring.
Note that while 'synthetic diamonds' can refer to lab created diamonds, some websites misuse this term to sell cubic zirconia.

Absolutely, lab grown diamonds are genuine diamonds. They are created using the same chemical and physical processes that occur naturally inside the Earth, but within a controlled laboratory setting. This process involves gradually enlarging a starter seed of diamond crystal as carbon atoms are deposited onto it. Lab made diamonds are chemically, physically, and optically indistinguishable from natural diamonds, making them scientifically valid as real diamonds. Notably, IGI and GIA, two leading global authorities on diamonds, grade man made diamonds using the same criteria and scale as mined diamonds.

The cost of lab created diamonds is significantly lower than that of mined diamonds. The exact saving depends on factors like size, quality, and type of diamond, but on average, lab created diamonds are around 75% less expensive. This is primarily because producing rough lab diamonds is less costly than mining natural diamonds. However, the subsequent processes for a diamond to become retail-ready (such as cutting, polishing, certification, shipping, and insurance) are the same for both lab and mined diamonds. For example, a lab diamond might cost only £2,500, compared to a staggeringly high £10,000 for an equivalent mined diamond.

Yes, lab created diamonds test as real diamonds. When examined with a diamond tester, they exhibit the same properties as natural diamonds, including hardness, refractive index, and thermal conductivity, due to their identical chemical, physical, and optical characteristics.

Similar to natural diamonds, most lab diamonds have inclusions which we explain in our lab diamonds guide. These are natural imperfections that occur in both types of diamonds and can vary in form, such as tiny bubbles or carbon deposits. While most lab created diamonds, just like mined diamonds, have some flaws, very few are created flawless. Our 4Cs guide provides more detailed information about the colour, clarity, cut, and carat of diamonds.

Yes, lab grown diamond rings in London, and jewellery too, can be insured just like mined diamonds, as all lab created diamonds are recognized as real diamonds. Insurance policies typically cover replacement or repair costs in cases of loss, theft, or damage. It's crucial to understand the terms of your policy fully. For more comprehensive information about what is covered and what is not, our lab diamond rings guide is an indispensable resource.
