Synthetic diamonds are now purer, more beautiful, and cheaper than mined

Market & Pricing Trends

• Many commenters say the “lab cheaper than mined” situation has existed for years; the big change is mainstream jeweler adoption.
• Reported retail prices for lab-grown: often ~$600–200/ct wholesale-equivalent, with 2–3ct stones around $1.2k–1.4k, versus many thousands for comparable mined.
• Several note huge price declines for lab diamonds and moissanite over the last decade; moissanite is now described as “near-worthless” per carat.
• Others point out retailers still maintain large markups and that diamond resale values (especially mined) are poor and have dropped over time.
• Some share sources for very cheap stones from Chinese/Indian platforms and caution about scams and weak third‑party certificates.

Status, Signaling, and Culture

• Repeated framing of mined diamonds as Veblen goods: value driven by conspicuous cost, branding, and “romance” rather than intrinsic properties.
• Engagement culture (especially in the U.S.) is criticized as consumerist and debt-inducing; others push back that practices vary widely by country and individual.
• Several note that many women are indifferent to diamonds, but social expectations and “three months’ salary” norms persist.
• Debate over whether natural diamonds will retain luxury status as a “real” or “authentic” good even when lab stones are visually superior.

Lab-Grown vs Natural: Quality and Terminology

• Consensus that lab diamonds can be purer, larger, and visually flawless; sometimes too perfect, lacking the “character” of natural inclusions.
• Some argue “synthetic/manufactured” diamonds are still fully “real” diamonds; others insist “artificial” is a legitimate descriptor and that natural vs synthetic is a meaningful distinction.
• It’s difficult for non-experts to distinguish lab vs natural; grading labs inscribe microscopic marks on lab stones.

Ethics and Human Impact

• Strong criticism of the historical diamond cartel, price-fixing, marketing (“diamonds are forever”), and links to conflict, exploitation, and environmental harm.
• Some foresee social stigma attaching to mined stones (“did a child slave mine that?”), though others think luxury buyers won’t care.

Industrial & Technical Uses / Future Outlook

• Thread highlights cheap industrial diamond: files, cutting tools, 3D printer nozzles, windows, heatsinks, optics.
• Discussion of potential diamond lenses, cookware, semiconductors, and heat spreaders, with technical caveats (brittleness, thermal expansion, doping).
• Many expect continued price collapse for both lab and mined diamonds, with large natural “investment-grade” stones seen as risky “bag holder” assets.
