Frequently Asked Questions
How much is a 3 carat lab grown diamond engagement ring?
This engagement ring starts at $2,162.79 USD and goes up to $2,900 USD depending on the options you choose. A mined diamond of similar size and quality usually costs several times more, which is why many buyers choose lab grown.
