The same stone as mined diamond, grown differently. Laboratory-grown diamond is diamond — the same carbon crystal, hardness 10, the same brightness and fire, and the same reading on a thermal tester — so it sets, polishes and wears exactly like mined diamond and sits unnoticed next to a mined centre stone. What differs is where it grew, what it costs, what a screening instrument reports, and the wording on your invoice: laboratory-grown diamond, never diamond alone. What's the same and what's different →
