Initially celebrated as the ethical and affordable alternative to mined diamonds, lab-grown diamonds are now experiencing a significant decline in value. What’s behind this dip, and what does it mean for the diamond industry? Let’s dive into the dazzling—albeit now slightly dimmed—world of lab-grown diamonds.

The Swift Decrease in Value

Lab-grown diamonds have seen a steep drop in their market value. Here’s a quick snapshot:

  • Depreciation Rate:  Unlike natural diamonds, which tend to retain value, lab-grown diamonds lose their worth almost immediately after purchase. (Money Under 30)
  • Price Plunge: For example, the price of a F-H colour and VS clarity 1.5-carat lab-grown diamond sold $10,300 in 2016 but then plummeted to $3,975 by 2021 (JCK) In comparison, a natural diamond in the same colour and clarity grades was listed in 2016 for $12,375 online, with the subsequent price in 2021 fetching $12,550.
  • Current Market: Forbes reports as of 2024, DeBeers’ Lightbox brand reduced prices to $600 australian dollars for a G-H colour VS clarity 1 carat brilliant cut diamond, while the equivalent natural diamond price is fetching $11,600.

Key Factors Driving the Decline

  • Market Saturation: Manufacturers flooding lab-grown diamonds into the market has driven prices down.
  • Production Advances: Improved and cheaper manufacturing techniques have lowered production costs, further reducing prices.
  • Quality Variability: The market is filled with stones of varying quality, with lower-quality stones dragging down overall value.
