About this 1.78ct natural oval diamond

This 1.78ct natural oval sits in the one-and-a-half to two carat band, graded M colour (faint-tinted) and VS2 clarity (very-slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 6341487672. Listed at 12 retailers as of November 5, 2026, with prices from £3,492 to £7,737, a £4,245 spread on the same certified stone. NZ Jewellers lists it at £7,737. Cut grade matters more than carat or clarity for visible brilliance. If you can shift budget toward an Excellent or Ideal cut, do it before chasing higher colour or clarity.
