About this 1.18ct lab-grown oval diamond

This 1.18ct lab-grown oval sits in the classic one-carat band, graded H colour (near-colourless) and VS1 clarity (very-slightly-included), with a standard cut grade and certified by IGI LG611391338 or 611391338. Listed at 19 retailers as of October 28, 2026, with prices from $342 to $1,355, a $1,013 spread on the same certified stone. Reve Diamonds lists it at $1,355. 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.
