About this 1.6ct natural oval diamond

This 1.6ct natural oval sits in the one-and-a-half to two carat band, graded H colour (near-colourless) and SI2 clarity (slightly-included), with a very-good cut grade and certified by GSI 98510300101. Listed at 6 retailers as of October 30, 2026, with prices from £6,653 to £12,054, a £5,401 spread on the same certified stone. NZ Jewellers lists it at £12,054. 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.
