Natural or Lab-Grown Diamond? How to Choose the Right One for Your Engagement Ring
Choosing the perfect diamond for your engagement ring can be a difficult decision to make, and today more couples are asking: Should I choose a natural diamond or a lab grown diamond? Both options offer undeniable beauty, brilliance and longevity. But understanding the differences between natural and lab-created diamonds is key. We’ve put together a comprehensive guide to help you understand the differences and make an informed decision that aligns with your values, lifestyle and love story.
At Affinity Diamonds, we believe that every ring should reflect not just your taste, but your story. This guide shares everything you need to know to make a confident decision - whether you’re drawn to the rare wonder of natural diamonds or the innovative brilliance of lab-grown stones.
What is the Difference between a Natural Diamond and a Lab-Grown Diamond?
Natural diamonds are formed over billions of years deep within the Earth’s mantle, created under extreme pressure and heat. Every natural diamond is a unique geological wonder with a long history - making it a powerful symbol of enduring love.
Lab-grown diamonds, also known as man-made or synthetic diamonds, are created in controlled laboratory environments using advanced technology that replicates the natural diamond-growing process. They are chemically, physically and optically identical to mined diamonds - the only difference is their origin.
Can You Tell the Difference Between Lab-Grown and Natural Diamonds?
To the naked eye, lab-grown and natural diamonds look identical. Given they have an identical chemical composition, both have the same hardness, sparkle and structure. This makes it impossible to tell the difference without specialised equipment to determine their origin. This makes lab-created diamonds a popular choice for those who want a diamond with the beauty of a mined stone, but at a more accessible price point.
Are Lab Grown Diamonds Cheaper?
Yes - lab-grown diamonds are typically 30-50% less expensive than natural diamonds of the same carat, cut, colour and clarity. Their lower price is due to a shorter production time and more scalable manufacturing process. For couples who want a larger diamond or a more elaborate setting, lab-grown diamonds offer incredible value.
Are Lab-Grown Diamonds Ethical? What About Natural Diamonds?
Lab-grown diamonds are often seen as the more sustainable and ethical option, as they don’t require traditional mining and generally have a lower environmental impact. However, it is important to recognise that natural diamonds can also be sourced responsibly - and Affinity Diamonds is deeply committed to ethical practices across both options.
As a member of the Diamond Dealers Club of Australia, Affinity Diamonds sources all natural diamonds in accordance with the Kimberley Process - a United Nations initiative that ensures rough diamonds are conflict-free and ethically traded.
Do Natural Diamonds Hold Their Value Better?
In general, natural diamonds have stronger long-term resale value due to their rarity, historical demand, and established position in the luxury market.
Lab-grown diamonds, whilst stunning and identical in composition, are more readily available and have a lower resale value. If you’re considering your diamond as both a symbol of love and a potential investment, this may be an important factor to consider.
What’s the Best Choice for Your Engagement Ring?
Your engagement ring should reflect your story, your values, and your style. Some couples are drawn to the romance and rarity of natural diamonds, formed over billions of years. Others prefer the innovation, affordability and sustainability of a lab-grown option. There’s no right or wrong choice, just the choice that feels right for you.
