About this 1.89ct lab-grown heart diamond

This 1.89ct lab-grown heart sits in the one-and-a-half to two carat band, graded F colour (colourless) and VS1 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG849602432 or 849602432. Listed at 9 retailers as of October 31, 2026, with prices from £277 to £1,179, a £902 spread on the same certified stone. Brilliant Earth lists it at £1,179. 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.
