In Part 1 of this series, we introduced the key differences between natural and lab-grown diamonds — how they are formed, their chemical similarities, and why lab-grown diamonds have become a popular topic in South Africa. In Part 2, we help you make the decision: which diamond is right for your specific situation, whether you are designing an engagement ring, buying a gift, or investing in fine jewellery?

A Quick Recap

Natural diamonds are formed deep in the earth over billions of years and extracted through mining. Lab-grown diamonds are created in a controlled environment using HPHT or CVD technology. The result is chemically and optically identical to a natural diamond — the only difference is origin and price.

Price: Lab-Grown Wins

Lab-grown diamonds are typically 50 to 70% less expensive than natural diamonds of the same carat weight, cut, colour, and clarity. Your budget goes considerably further — a larger stone, a higher quality grade, or a more intricate custom setting for the same cost as a smaller natural diamond.

Resale Value: Natural Wins

This is the most significant practical consideration. Natural diamonds hold their value better over time. The resale market for lab-grown diamonds in South Africa is still developing, and because they can be produced at scale, resale prices are generally lower. If long-term investment value matters to you, a natural diamond is the stronger choice.

Ethics & Sustainability: It’s Nuanced

Lab-grown diamonds avoid the environmental and social impacts of mining — a genuine advantage. However, they are energy-intensive to produce, and their environmental footprint depends on the energy sources used by the laboratory. Natural diamonds, sourced through reputable suppliers adhering to the Kimberley Process, can also be obtained ethically. At Gold and Diamond Traders, we source our stones responsibly and are happy to discuss provenance.

For Custom Engagement Rings: Our Take

Choose a lab-grown diamond if budget is a priority, you want maximum size or quality for your money, or if ethical sourcing is your primary concern.

Choose a natural diamond if long-term value, tradition, and the unique romance of a stone formed over billions of years matter most to you.

We have manufactured stunning engagement rings with both. The visual quality difference is genuinely negligible — what matters is what the stone means to you.
