Deciding on a lab or mined diamond is vital for those considering purchasing precious diamond jewellery. Diamond adornment is a personal aesthetic choice. Our goal is to give you all the information you need to make an informed decision on whether to opt for lab or mined diamonds.

At OM Gold & Diamonds we create stunning designs using both. Whatever your preference, you can trust us to source exquisite diamonds. Our focus is always on quality and we offer an array of cuts. We believe diamond jewellery should resonate in the heart of the wearer and that you should have complete confidence in your choice.

Mined Vs Lab-Grown Diamonds: Key differences

The main difference between lab diamonds and ‘natural’ diamonds is their origins. Lab diamonds (or laboratory diamonds) are created. Mined diamonds occur naturally in the Earth’s crust in limited quantities, and are sourced through mining.

The value placed on where a diamond came from varies between cultures and individuals – asking your partner about their preferred diamond may inform your decision.

So lab and mined diamonds are the same? Not quite

A lab diamond is just as hard as a mined diamond and is capable of achieving the same lustre and cut. But while mined diamonds take billions of years to develop, lab diamonds are generally created in less than a month, with science imitating the natural development process. It is difficult even for professionals to differentiate the two types without appropriate equipment.

So, is a lab or mined diamond the smarter choice? A few factors need to be considered before deciding on your preference.

Cost comparison

A lab diamond is much less expensive than a mined diamond of similar quality. The difference in cost can be up to 30-40%. As a result, a lab diamond will be more impressive in size or quality than a mined diamond at any given budget.

The price gap is a huge part of the appeal lab diamonds hold for modern jewellery lovers. A ring with a lab diamond is going to be more accessible for clients working with a limited budget, hence the rise in popularity.

A warning on resale value

However, if you plan to resell your jewellery at a later date, a mined diamond will offer a much higher return. Unlike mined diamonds, lab diamonds do not increase or even maintain value. Their resell value is much lower.

Assessing diamond quality

Grading and certification can be obtained for both types of diamonds. At OM Gold & Diamonds we provide our clients with ethically sourced diamonds and only use reputable suppliers. We pride ourselves on our transparency.

When it comes to the four Cs of Diamonds — colour, clarity, cut, and carat — both types of diamonds perform beautifully. Lab diamonds, though formed differently, are still diamonds, unlike other clear sparkling options on the market.

What about other diamond alternatives?

Moissanite and cubic zirconia are not diamonds and sparkle completely differently. Moissanite is simulated to resemble diamonds but created from another substance; Cubic Zirconia is man-made and less durable.
