Lab Grown Diamond Engagement Rings at One Mo Diamond

Lab-grown diamond engagement rings are redefining the jewellery industry. Combining timeless elegance with 21st-century innovation, these diamonds are more than just beautiful; they are a modern, ethical, and affordable choice. With their rising popularity across Europe, lab-grown diamonds offer a sustainable alternative to traditionally mined diamonds. Visually identical and every bit as dazzling, they give couples the opportunity to indulge in luxurious designs while supporting transparency and environmental responsibility. At One Mo Diamond, we pride ourselves on offering a diverse collection of lab-grown diamond engagement rings made to perfection.

What Are Lab-Grown Diamonds?

Lab-grown diamonds are real diamonds. Scientifically, they share the same physical, chemical, and optical properties as their mined counterparts. However, unlike natural diamonds—which are formed deep within the Earth’s crust over millions of years—lab-grown diamonds are created efficiently in controlled settings using state-of-the-art technology.

Two primary methods are used to create lab-grown diamonds:

  • High-Pressure High-Temperature (HPHT): Mimics the natural formation conditions with heat and pressure.
  • Chemical Vapour Deposition (CVD): Carbon layers grow on a seed crystal to form a diamond.

Lab-grown diamonds are sustainably produced and ethically sourced. Often certified by trusted organisations like IGI and GIA, they offer the same clarity, brilliance, and durability as natural diamonds. Choosing lab-grown means choosing sophistication and ethics without compromise.

Why Choose Lab-Grown Diamond Rings?

  • Affordability: 30–50% more affordable than natural diamonds.
  • Eco-Conscious: Created with minimal environmental impact.
  • Ethical Sourcing: Conflict-free origins and transparent practices.
  • Bigger Brilliance: Enjoy larger, higher-quality diamonds within budget.

A lab-grown diamond engagement ring is the ideal symbol of love for environmentally and socially conscious couples who value brilliance, craftsmanship, and sustainability.

Design Options Available

  • Styles: Solitaire, Halo, Trilogy, Vintage-inspired, Contemporary.
  • Diamond Shapes: Round, Oval, Cushion, Pear, Emerald.
  • Metals: White Gold, Yellow Gold, Rose Gold (14K & 18K), Platinum.
  • Finishes: Polished, Matte, Brushed.
  • Customisation: Choose carat, cut, clarity, colour, and setting.

Comparison: Lab-Grown vs. Natural Diamonds

Similarities:

  • Appearance and brilliance are identical.
  • Same hardness and durability.

Differences:

  • Lab diamonds are more affordable.
  • Created in controlled labs vs. mined from Earth.

Lab-grown diamonds are perfect for those seeking ethical, beautiful, and budget-conscious options.

The difference is in gold purity. 14K gold (also called 585) contains 58.5% pure gold and 41.5% other metals. 18K gold (also called 750) contains 75% pure gold and 25% other metals. Because 18K has more gold in the alloy, it has a richer colour and is more expensive. Pure gold (marked 999 or 24K) is very soft, so jewellery is usually made from 14K or 18K gold — for better strength and everyday wear.
All One Mo Diamond jewellery is ready to ship within 1–2 business days.

Of course, only a jeweller can give the most accurate answer to such a question :) But if you don’t have the chance to visit one, you can try to measure your ring size at home: Use a ring that already fits you well – measure its inner diameter and compare it to a size chart. If you’re still unsure, feel free to contact us at info@onemodiamond.com – we’ll be happy to help you find the perfect fit.
