About this 3.57ct lab-grown round diamond

This 3.57ct lab-grown round sits in the three to five carat band, graded I colour (near-colourless) and VS1 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG605341390 or 605341390. Listed at 11 retailers as of October 29, 2026, with prices from $504 to $2,586, a $2,082 spread on the same certified stone. MOH London lists it at $2,586. 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.
