About this 1.71ct lab-grown heart diamond

This 1.71ct lab-grown heart sits in the one-and-a-half to two carat band, graded D colour (colourless) and VS1 clarity (very-slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 5453396965. Listed at 17 retailers as of October 27, 2026, with prices from £303 to £2,180, a £1,877 spread on the same certified stone. Queensmith lists it at £2,180. 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.
