Affordable Luxury: Lab Grown Diamonds in Hong Kong

Every few weeks someone asks me some version of "should I wait for lab-grown diamonds to get even cheaper?" I used to give a vague answer. I don't anymore, because the pricing data in front of me every day as a buyer says something fairly specific: for lab-grown, the floor is now — not next year.

Quick take

  • Natural diamond prices fell 15–30% from their 2022 peak and have held roughly steady through 2025–2026.
  • Lab-grown diamond prices are sitting close to their floor right now — raw material costs keep falling, but rising industrial demand is pushing cutting and polishing costs the other way.
  • If you've been waiting for lab-grown to get meaningfully cheaper, that wait is largely over.

Two Different Price Curves in the Lab-Grown Diamond Market Right Now

Natural and lab-grown diamonds are on genuinely different trajectories, and conflating them is where most of the confusion comes from.

Natural diamonds
-15% to -30%

Fell from the 2022 peak, then largely stabilized through 2025–2026. The correction has mostly played out.

Raw material cost keeps declining, but rising industrial demand is pushing polishing and cutting costs up — the two roughly offset each other in 2025–2026.

Why Lab-Grown Diamond Prices Aren't Dropping Much Further

The instinct is to assume lab-grown gets cheaper every year, forever — more labs, more supply, lower price. That was true for a while. What's changed is that lab-grown material now has real industrial demand outside jewelry, which is pulling on the same cutting and polishing capacity that finishes engagement rings. That's a cost that doesn't disappear just because the raw crystal got cheaper to grow. The practical result: retail prices on finished, certified stones have flattened out rather than kept falling.

None of this is unique to MadisonDia's pricing — it's the shape of the market itself, and it's the same reason I tell people not to keep waiting on the sidelines for a bigger drop that isn't coming.

What This Means If You're Buying a Lab-Grown Diamond in Hong Kong

If your plan was "buy when it's cheapest," this is close to that point for lab-grown. If your plan was "buy natural once prices bottom out," that's also mostly already happened. Either way, the pricing argument for delaying further has weakened. The decision left is really about which type of stone fits your budget and values — not about timing the market.

Why the Lab-Grown Diamond Price Floor Sits in Hong Kong

Part of why lab-grown pricing can sit this close to the floor without cutting corners on quality comes down to where the stones get finished. Hong Kong has one of the highest concentrations of gold and fine jewelry trading in Asia — walk through Tsim Sha Tsui or Mong Kok and you'll pass a jewelry counter on nearly every block. That density means cutting, polishing, and setting expertise is close at hand rather than outsourced across borders.

Free port, no general sales tax

Hong Kong doesn't apply VAT or general sales tax on retail goods, including fine jewelry — so the price on the stone or ring is closer to the actual price, without a tax layer stacked on top.

Craftsmanship on the doorstep

A dense local trade in cutting, polishing, and setting means less added cost from shipping half-finished stones elsewhere for the final work.

Put together — a tax-free retail environment and craftsmanship concentrated locally rather than fragmented across supply chains — Hong Kong is a natural base for lab-grown diamonds to sit near their price floor while the finishing quality stays high.

Frequently Asked Questions

Will lab-grown diamond prices drop further in 2026?

Unlikely to drop much further in the near term. Raw material costs are still falling, but rising industrial demand for lab-grown material is pushing up cutting and polishing costs elsewhere in the supply chain, which is keeping finished-stone prices roughly flat.

Have natural diamond prices finished falling?

Natural diamond prices fell 15–30% from their 2022 peak and have been relatively stable through 2025–2026 — the sharpest part of that correction appears to be behind us.

Is now a bad time to buy because prices might fall later?

Based on current pricing dynamics, waiting for a significant further drop in lab-grown prices isn't well supported by the data. If you're ready to buy, the pricing argument for delaying has weakened.
