About this 0.51ct lab-grown oval diamond

This 0.51ct lab-grown oval sits in the half to three-quarter carat band, graded E colour (colourless) and SI1 clarity (slightly-included), with a very-good cut grade and certified by IGI LG847690786 or 847690786. Listed at 10 retailers as of November 6, 2026, with prices from $124 to $408, a $284 spread on the same certified stone. Michael Trio lists it at $408. 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.
