About this 1.8ct natural oval diamond

This 1.8ct natural oval 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 and certified by IGI 732579307. Listed at 7 retailers, with prices from $4,886 to $9,980 at MOH London, a $5,094 spread on the same certified stone. 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.
