This 2.5ct lab-grown heart sits in the two to three carat band, graded D colour (colourless) and VS1 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG816683457 or 816683457. Listed at 20 retailers as of October 30, 2026, with prices from £312 to £2,694, a £2,382 spread on the same certified stone. Brilliant Earth lists it at £2,694. 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.
