What are the main differences between lab-grown and natural diamonds?
The main differences between lab-grown and natural diamonds are the place of origin and the price. Natural diamonds are created within the Earth's mantle millions of years ago due to extreme heat and pressure. Lab-grown diamonds are made within months inside a chamber that can re-create the same conditions as the Earth's mantle.
Price is where there is the most apparent difference. Lab-grown diamonds are typically 50% less than an equivalent quality natural diamond. The price disparity will increase even more the heavier you go in the diamond's carat weight.
In most cases, you can also get a lot more for your money with a lab-grown diamond as well as a higher quality stone.

What are the similarities between lab-grown and natural diamonds?
Visually, optically, and physically, both options are identical. The only way to tell the difference between the two is by checking the laser inscription on the stone to see what the certificate number is. You can then search for the certificate number on GIA, IGI, or GCAL's respective websites to see if the diamond is natural or made in a lab.
If there is no certificate number engraved onto the diamond, then you would need to visit a jeweler to help test the diamond for you or submit the diamond to GIA, IGI, or GCAL.
Are lab diamonds real diamonds?
Yes. Lab diamonds are real diamonds; they are just made in a lab. They have the same chemical composition as natural diamonds being 100% carbon.
Are lab-grown diamonds the same as moissanite or cubic zirconia?
No. Diamonds, moissanite, and cubic zirconia are each distinct individual stones with different chemical compositions. Lab-grown diamonds are pure carbon, moissanites are silicone-carbide, and cubic zirconias are zirconium dioxide.
Do lab-diamonds hold any re-sale value like natural diamonds do?
Yes. You can re-sell lab-grown diamonds. Traditional jewelers of mined diamonds regularly lie to the public, claiming that there is no resale market for lab-grown diamonds. This is false. At our store, you can re-sell both your lab-grown or natural diamonds.
Whether the diamond is lab-grown or natural, the value retainment depends on the supply and demand from consumers. Buying a diamond engagement ring with a lab-grown or natural diamond should be considered a discretionary, luxury purchase, and not an investment. The diamonds used in engagement rings are historically not a good place to invest your money. You should treat your lab or natural diamond engagement ring for what it is. A beautiful piece of wearable art and representation of your love that will last forever.
Investment grade diamonds need to be extremely rare, and will typically cost millions of dollars.
