About this 1.23ct lab-grown oval diamond

This 1.23ct lab-grown oval sits in the classic one-carat band, graded D colour (colourless) and VS1 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG753506677 or 753506677. Listed at 18 retailers as of November 1, 2026, with prices from $227 to $2,180, a $1,953 spread on the same certified stone. Do Amore Diamonds lists it at $2,180. 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.
