  • Lab Diamonds cost significantly less than Natural Diamonds

A “Lab Grown Diamond” is just like a Natural Diamond, except instead of growing in the Earth, they grow in a lab. A “Lab Grown Diamond” will have the same or similar chemical and physical properties as a Natural Diamond produced by the geological process as Mother Nature. There is no visual difference in Lab Created Diamonds vs Natural Diamonds. They sparkle the same, have the same color and clarity, and can come in the same sizes and shapes. Similarly, Lab Grown Diamonds have the same hardness as Natural Diamonds.
