Online-only auction formats for natural diamond resale are growing faster than traditional in-room sales, widening access to a market once dominated by physical attendance.

  • Online formats lower the barrier to bidding, bringing in buyers who wouldn't travel to or register for an in-room sale for a single lot.
  • Detailed video and imaging standards for online lots have improved enough that condition and quality concerns are less of a barrier than they once were.
  • Prices achieved online for comparable lots have generally tracked in-room results closely, suggesting the format shift hasn't meaningfully changed valuations.

If you're considering reselling a natural stone, it's worth comparing online auction, in-room auction and private sale routes before choosing one. Ask the trade desk for a read on which route suits a specific stone.
