About this 3ct lab-grown round diamond

This 3ct lab-grown round sits in the three to five carat band, graded J colour (near-colourless) and VS2 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG499190392 or 499190392.

If you can shift budget toward an Excellent or Ideal cut, do it before chasing higher colour or clarity.
