The Diamond Debate: Lab-Grown vs Natural
Few topics in the jewellery world generate more discussion than the choice between lab-grown and natural diamonds. Both have real merit, and the right choice depends entirely on your priorities. Corelune Jewellery offers both options and will always help you make the decision that is right for you.
What Are Lab-Grown Diamonds?
Lab-grown diamonds are real diamonds — they share the same chemical composition, crystal structure, and optical properties as mined diamonds. They are created in controlled laboratory environments using two main methods: High Pressure High Temperature (HPHT) and Chemical Vapour Deposition (CVD). Neither method can produce a diamond that a gemologist can distinguish from a mined diamond without specialised equipment.
How Do They Compare in Quality?
Lab-grown diamonds are graded using the same 4Cs criteria as natural diamonds — cut, colour, clarity, and carat. They are available across the full range of quality grades, from flawless to included. There is no difference in hardness, brilliance, or durability between a lab-grown and a mined diamond.
Price Difference
Lab-grown diamonds are typically 30–50% less expensive than equivalent natural diamonds. This price gap has widened in recent years as lab-grown production has scaled up. This means you can often afford a significantly larger or higher-quality stone for the same budget if you choose lab-grown.
Environmental and Ethical Considerations
Lab-grown diamonds have a significantly smaller physical environmental footprint than mined diamonds — no open-pit mining, no habitat disruption, and no risk of conflict diamond sourcing. However, they do require significant energy to produce, and the environmental impact depends greatly on the energy source used.
Long-Term Value
Natural diamonds have historically held their value and can appreciate over time, particularly for rare or high-quality stones. Lab-grown diamonds currently have a lower resale value, which is worth considering if long-term investment value is important to you.
