Thinking of buying lab-grown diamonds? Read more to find out what lab-grown diamonds are, how they are made, the difference between lab-grown and naturally mined diamonds, and their benefits.
Yes. Lab diamonds and mined diamonds have the same physical and chemical structure and are both real diamonds. Their only difference is their origin - mined diamonds are formed deep beneath the Earth’s surface, while lab diamonds are created in a controlled laboratory environment.
Yes. Both lab-grown diamonds and natural diamonds can crack under extreme pressure. However, as the most durable gemstone on Earth (ranking a 10 on the Mohs hardness scale), damaging either type during daily wear is highly unlikely.
Lab-grown diamonds and mined diamonds have the same chemical composition, crystal structure and physical properties, and they are visually and optically identical. Lab-grown diamonds have the same 4Cs (Cut, Colour, Clarity and Carat weight) as mined diamonds when evaluating their quality and value. ZCOVA’s lab diamonds are IGI-certified so you can be assured of its authenticity.
Generally, lab-grown diamonds are less expensive than mined diamonds. However, the cost of a lab-grown diamond will depend on factors such as the 4Cs - Cut, Colour, Clarity and Carat weight.
Choosing the right lab-grown diamond and setting depends on your personal preferences, price range and occasion.
For a classic look, go for a round diamond. Princess, cushion, and radiant shapes are a popular choice for those who love extra sparkles. To make your fingers appear longer, you may choose elongated shapes like marquise, pear or oval. For something more vintage, asscher and emerald are ideal. Lastly, heart-shaped diamonds are perfect for those who want a unique and romantic design.
If you prefer a simple and classic design, the solitaire setting is for you. The halo setting can make the centre diamond appear bigger. For extra sparkles and glam, go for a pavé setting.
