Lab Grown Diamond Ring Prices 2026: What You Pay by Carat
Lab grown diamonds cost far less than mined diamonds of the same size, and their prices have fallen a lot in recent years. At Bhumi Gems, a lab grown diamond engagement ring costs about $1,200 to $1,350 for 1 carat in 14K gold, and about $1,650 to $1,800 for 2 carats. Here are our real prices by carat and metal, what changes the price, and how to get the most diamond for your budget.

What decides the price
1. Carat weight
With lab grown diamonds, the stone is most of the price. In our store, going from 1 to 2 carats adds about $450, and from 2 to 3 carats about $600. That is a much gentler climb than with mined diamonds, where larger stones are rare and the price per carat jumps sharply.
2. Color and clarity
We use E-F color and VVS clarity, which is near the top of both scales. Elsewhere you will see lower grades such as G-H color or VS clarity for less money; at normal viewing distance many people cannot see the difference. If you compare prices between sellers, compare the same grades.
3. The metal
Moving from sterling silver to 14K gold adds about $300 on our lab grown rings. For a ring worn every day, solid gold or platinum lasts better. Yellow and rose on sterling silver and platinum are plated finishes. See white gold vs platinum.
4. The design
A plain solitaire is the most affordable. Bezel, three stone, halo and hidden halo designs add metal, small stones and setting work, usually a modest amount on top.
5. Grading reports
Some sellers include an independent laboratory grading report, which adds to the cost. Every Bhumi Gems piece comes with our own certificate of authenticity stating the stone, carat and metal; independent lab reports are not included.
Why lab grown diamond prices keep falling
Lab grown diamonds are made in factories using two methods, CVD and HPHT, and production has grown and become more efficient year after year. More supply and cheaper production have pushed prices down steeply since around 2020. That is good news if you are buying, but it also means lab grown diamonds resell for little. We explain both sides in are lab grown diamonds worth it? and CVD vs HPHT.
Lab grown diamond vs moissanite vs mined diamond
For a 2 carat solitaire in 14K gold in our store:
- Moissanite: about $550 to $575. See our moissanite ring price guide.
- Lab grown diamond: about $1,650 to $1,800.
- Mined diamond: many times more for a similar size and quality.
A lab grown diamond is a real diamond with the same hardness and white sparkle as a mined one. Moissanite is a different gem with more rainbow fire and a much lower price. Compare them in moissanite vs lab grown diamond.
How to get the most for your budget
- Choose a shape that looks bigger. Oval, pear and marquise look larger per carat than round. See oval vs round.
- Spend on the stone, then the metal. 14K gold is the usual sweet spot for daily wear.
- Add sparkle with the setting. A halo or hidden halo makes a 1 carat centre look bigger. Browse hidden halo engagement rings.
- Do not buy for resale. Buy the ring you love wearing.
