About this 1.21ct lab-grown oval diamond

This 1.21ct lab-grown oval sits in the classic one-carat band, graded G colour (near-colourless) and VS1 clarity (very-slightly-included), with a standard cut grade and certified by IGI LG600347630 or 600347630. Listed at 17 retailers as of October 31, 2026, with prices from $346 to $1,899, a $1,552 spread on the same certified stone. Taylor and Hart lists it at $1,899. 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.
