Lab-grown diamonds have the same chemical composition and physical properties as mined diamonds. Tests available on the high street will not be able to tell the difference. The only way to tell them apart is by testing using specialist laboratory equipment.
Lab-grown diamonds are grown from a diamond seed by replicating the same conditions that would have occurred naturally. Just as with mined diamonds, they can have slight imperfections and colour differences.
No. Lab-grown diamonds have the same chemical and physical makeup as mined diamonds and will not change over time any more than a natural diamond will.

Yes. As with any individual piece of jewellery or expensive item in your home, you should be sure it’s covered by your insurance.
The very act of extracting diamonds from the earth is hugely expensive in equipment, manpower, time and transportation. All of these costs are added to the price of the diamond that you pay for. A lab-grown diamond is less costly to create, and therefore less expensive to purchase.
A fake diamond is an imitation stone such as cubic zirconia or moissanite. These may have a diamond-like appearance but are made of completely different materials and properties.
