0.87ct I SI1 Radiant Lab Grown Diamond

About this 0.87ct lab-grown radiant diamond

This 0.87ct lab-grown radiant sits in the just-under-one-carat band, graded I colour (near-colourless) and SI1 clarity (slightly-included), with a very-good cut grade and certified by IGI LG407950377 or 407950377. Listed at 11 retailers as of October 31, 2026, with a 247% spread between the cheapest and most expensive listing. That is exactly the kind of price-discovery gap Carat Hunter was built to surface. 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.
