What Determines Lab-Grown Diamond Prices?

Short answer: The price of a lab-grown diamond, and so of a solitaire ring, is set by the stone’s carat, cut, colour and clarity and by the ring’s setting. It is far more affordable than a natural diamond with the same characteristics. Because every stone is unique and prices change, we give a current price for your choice rather than a fixed list.

Why is there no fixed price list?

No two diamonds are identical. Two stones of the same carat can differ in price by a single grade of colour or clarity. On top of that come the gold price and the workmanship of the setting. So an accurate price can only be given for a specific stone and a specific design.

To make this easy, in our ring designer you can choose the stone’s shape, carat and gold colour and send your choice to us on WhatsApp with a single tap.

Six things that set the price

1. Carat

This affects the price most. Price does not rise in a straight line with carat; as the stone gets bigger, the price per carat rises too. There is also a jump at round values such as 1, 1.5 and 2 carats. More: what is a carat.

2. Cut

It has two meanings: the stone’s shape (round, oval, emerald…) and the quality of the cut. The round cut is usually more expensive than other shapes because it is the most in demand and loses the most rough in cutting. Cut quality decides how much the stone will sparkle.

3. Colour

The closer the stone is to colourless, the higher the price. D–F is colourless, while G–H is the class that looks white when worn.

4. Clarity

A stone with fewer marks inside is more expensive. VS stones and above look clean to the naked eye. Colour and clarity in detail: diamond colour and clarity.

5. Certificate

A report from an independent laboratory documents the stone’s characteristics and shows what the price is based on. More: GIA and IGI certificates.

6. Setting

This is the ring that holds the stone. The gold’s purity and weight, whether there are side stones and the fineness of the workmanship all add to the total. A plain solitaire setting costs differently from one with side stones or a halo.

How does the price compare with natural diamond?

A lab-grown diamond is noticeably more affordable than a natural diamond of the same carat, colour and clarity. The reason is not a difference in quality but in origin: a natural diamond is mined and rare, while a lab-grown diamond is grown under controlled conditions within weeks. Chemically, both stones are the same diamond.

You can use this difference in two ways: buy a bigger or higher-quality stone for the same budget, or buy the same stone for a smaller budget.

Five ways to make the most of your budget

• Do not compromise on cut. The cut is what makes a stone sparkle; a well-cut stone looks bigger and livelier than it is.
• Eye-clean clarity is enough. VS clarity looks the same as VVS when worn.
• Choose a colour that looks white when worn. G–H colour looks colourless to most eyes.
• Look just below the round numbers. The size difference between 0.90 carat and 1 carat, for example, is hard to see.
• Consider elongated cuts. Oval, pear and marquise cuts look bigger at the same carat.
