About this 3.73ct lab-grown oval diamond

This 3.73ct lab-grown oval sits in the three to five carat band, graded H colour (near-colourless) and VS1 clarity (very-slightly-included), with a standard cut grade and certified by IGI LG570365495 or 570365495. Listed at 18 retailers as of October 31, 2026, with prices from $1,032 to $4,143, a $3,111 spread on the same certified stone. Brilliant Earth lists it at $4,143. 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.
