About this 0.73ct lab-grown oval diamond

This 0.73ct lab-grown oval sits in the half to three-quarter carat band, graded H colour (near-colourless) and SI1 clarity (slightly-included), with a very-good cut grade and certified by IGI LG414059517 or 414059517. Listed at 11 retailers as of November 5, 2026, with prices from $830 to $4,573, a $3,743 spread on the same certified stone. MOH London lists it at $4,573. 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.
