Well, you don't put emphasis on the price. I recently got my wife some diamond earrings. I would have bought her mined diamonds, but was considering lab produced stones. What is the difference? The difference is that lab stones are essentially "organic" diamonds - they cut out the suffering and corruption (pesticides) from the production of something nice. She liked the idea of getting a product that is part of an ethical supply chain. I enjoyed getting a nicer stones for half the price.
