What makes this marquise split shank 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 1.0 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

Almost everyone hits the same wall. The shape is decided within a week; the size takes months, because the natural diamond that looks right costs three to five times what feels sensible to spend.

Why Solid Gold Changes Everything

Lab grown diamonds close that gap without asking you to accept a lesser stone. Identical hardness, identical brilliance, identical certification categories - a different origin and a different price. Combined with a solid gold setting, that means a bigger stone on a ring built to be worn every day. Every marquise split shank engagement ring we make is hallmarked and built to the same standard.

Picture This

Imagine it on the hand rather than in the box. At 1.0 carat the stone is large enough to read across a room, and the marquise outline is what makes it recognisable. This is the version of the ring you pictured before you started worrying about price. A marquise split shank engagement ring is the piece people remember.

Frequently Asked Questions

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

How much is a 1 carat lab grown diamond engagement ring?

A 1 carat lab grown diamond engagement ring at Qutahia starts from around £1,100 in 9ct gold, £1,360 in 14ct and £1,575 in 18ct. Cut affects the price: emerald is the most affordable, marquise the highest. A natural diamond of the same weight typically costs three to five times more.

What is a split shank engagement ring?

A split shank ring has a band that divides into two as it approaches the centre stone. The split frames the diamond and makes it appear raised and larger, and the wider profile suits bigger centre stones.

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.

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.

Is a lab grown diamond a real diamond?

Yes. A lab grown diamond is a real diamond, not a simulant. Cubic zirconia and moissanite are different materials; a lab grown diamond is diamond itself, and is certified as such.

What is the difference between lab grown and natural diamonds?

Only the process of formation. A natural diamond forms underground over millions of years; a lab grown diamond is produced in weeks with the same crystal structure. Hardness, brilliance and chemical composition are identical. The price difference is three to five times.
