Why are you still paying 97% more for the same stone?

A 3-carat Colombian Emerald with no inclusions can cost $30,000 or more. The lab grown version (chemically identical, visually indistinguishable, certified by the same gemological labs) costs $135. Same crystal structure. Same refractive index. Same deep green colour. The only difference is that one took millions of years underground and the other took a few weeks in a controlled environment. Use the calculator on the right to see exactly how much you'd save on any carat weight, any quality, any origin.
