About this 1ct lab-grown oval diamond

This 1ct lab-grown oval sits in the classic one-carat band, graded H colour (near-colourless) and SI2 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 3545665724. Listed at 3 retailers as of October 30, 2026, with prices from $1,539 to $2,488, a $948 spread on the same certified stone. 77 Diamonds lists it at $2,488. 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.
