About this 1.61ct lab-grown round diamond

This 1.61ct lab-grown round sits in the one-and-a-half to two carat band, graded H colour (near-colourless) and SI1 clarity (slightly-included), with a very-good cut grade. Listed at 4 retailers as of October 29, 2026, with prices from £139 to £554, a £415 spread on the same certified stone. NZ Jewellers lists it at £554. 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.
