How much does a lab-grown engagement ring cost?

The centre diamond, the gold and the setting set the price. Here is one design across sizes, the Classic Bond oval solitaire in 14K gold, November 2026:

  • 0.5 carat: ₹45,099
  • 1 carat: ₹64,799
  • 1.5 carat: ₹83,199
  • 2 carat: ₹1,06,699
  • 3 carat: ₹1,66,599

The same ring with a 1 carat centre costs ₹78,299 in 18K and ₹94,399 in 22K. Settings with more diamonds or more gold cost more: a round bezel solitaire with a 1 carat centre is ₹87,899 in 14K. Prices move with the gold rate, and each product page shows the full breakup. See our solitaire ring price guide for more sizes.

Choose the shape first

  • Round: the most brilliant cut, timeless and easy to wear.
  • Oval: lengthens the finger and looks larger than a round of the same weight.
  • Pear: a teardrop with direction, elegant and a little different.
  • Emerald: step-cut flashes rather than sparkle, clean and architectural.
  • Radiant and cushion: square or rectangular outlines with lots of sparkle.
  • Marquise: long and slim, the most finger-lengthening shape.

How big should the centre diamond be?

0.5 to 1 carat looks refined and suits slim fingers and daily wear. 1 to 1.5 carat is the most versatile range: clearly visible without feeling heavy. 2 carat and above is a statement. Lab-grown diamonds cost far less per carat than mined ones, so many couples choose a larger stone for the same budget. Our 1 carat diamond ring guide shows how each size looks on the hand.

Which setting?

  • Solitaire: one diamond on a plain band. The classic choice and the easiest to pair with a wedding band.
  • Pavé: small diamonds along the band for extra sparkle.
  • Hidden halo: a ring of small diamonds under the centre stone, visible from the side.
  • Bezel: a rim of gold around the diamond. Smooth, secure and good for active hands.

Which gold?

14K and 18K gold are harder than 22K and hold a centre stone more securely for daily wear. Yellow gold is warm and traditional, white gold makes the diamond look icier, and rose gold flatters warm skin tones. All three purities are BIS hallmarked.
