What makes this marquise lab diamond engagement ring different

Most rings at this price are plated or set in low-purity alloy. This one is solid gold throughout, hallmarked, and built around a certified stone. The marquise outline was chosen because it carries weight visually - at 2.0 carat it reads larger than a round stone of the same weight. See the full diamond collection for other shapes and carat weights.

The Problem

Ring shopping tends to go the same way. You set a budget, then discover that the natural stone at that price is half the size you pictured. The choice becomes compromise on the stone or stretch the budget, and neither feels good.

Why Solid Gold Changes Everything

A lab grown diamond removes that trade-off. It is the same material as a mined diamond - pure carbon, hardness 10 - grown in weeks rather than millions of years. Because supply is not constrained, the same budget buys a substantially larger stone. Set in solid hallmarked gold rather than plated brass, the ring lasts the way an engagement ring should. Every marquise lab diamond engagement ring we make is hallmarked and built to the same standard.

Picture This

Picture the moment you take it out. The stone catches the light before anything is said, and the size registers immediately - that is what a 2.0 carat centre stone does at arm's length. Years later it is still the ring being noticed, because solid gold does not wear thin and a diamond does not dull. A marquise lab diamond engagement ring is the piece people remember.

Frequently Asked Questions

The questions below are the ones buyers ask most often before choosing a marquise lab diamond engagement ring.

How much is a 2 carat lab grown diamond engagement ring?

A 2 carat lab grown solitaire starts from around £1,790 in 9ct gold and £2,370 in 18ct. The same stone as a natural diamond would sit between £12,000 and £20,000 at UK retail.

What is a marquise cut diamond?

A marquise is an elongated shape with pointed ends. It covers more finger than any other cut at the same carat weight, which is why it reads as the largest stone for the money.

Are lab grown diamonds certified?

IGI and GIA both certify lab grown diamonds. The certificate confirms carat, colour, clarity and cut, and states clearly that the stone is lab grown.

How do I clean a lab grown diamond engagement ring?

Warm water, a few drops of washing-up liquid and a soft toothbrush are enough. Doing this once a month keeps the stone bright. Avoid chlorine and abrasive cleaners - the risk is to the gold setting rather than the stone.

Lab grown diamond or moissanite - which is better?

Moissanite is not a diamond; it is silicon carbide. It throws more colour and costs less, but its hardness is 9.25. A lab grown diamond is harder at 10 and is certified as a diamond.

Are lab grown diamonds acceptable for an engagement ring?

A lab grown engagement ring is no longer a minority choice in the UK. It is a common decision among younger buyers, largely because the same budget buys a noticeably larger stone.

Are lab grown diamonds good for engagement rings?

Yes. A lab grown diamond is chemically and physically identical to a mined diamond: pure carbon, 10 on the Mohs hardness scale. There is no durability difference for daily wear. The only differences are where it formed and what it costs.
