What makes this oval three stone 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 oval outline was chosen because it carries weight visually - at 1.5 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

You have probably found the same thing everyone else does when they start looking. A natural diamond at the size you actually want costs more than you planned, and the stones inside your budget look smaller in person than they did online. Most people end up choosing between the size they wanted and the price they can justify.

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 oval three stone 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 1.5 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. An oval three stone engagement ring is the piece people remember.

Frequently Asked Questions

The questions below are the ones buyers ask most often before choosing an oval three stone engagement ring.

How much is a 1.5 carat lab grown diamond engagement ring?

A 1.5 carat lab grown solitaire starts from around £1,400 in 9ct gold, £1,700 in 14ct and £1,930 in 18ct. Going from 1 carat to 1.5 carat adds roughly 27% to the price, not 50% - carat weight and price do not rise in step.

What does a three stone engagement ring mean?

A three stone ring has a centre diamond flanked by two side stones. The three stones are commonly read as past, present and future. Practically, the side stones add width and make the ring read larger on the finger.

Why choose an oval diamond for an engagement ring?

An oval stone looks larger than a round diamond of the same carat weight because more of its surface faces upward. The elongated outline also lengthens the finger. Oval is currently one of the two most requested shapes in the UK.

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.

Do lab grown diamonds have resale value?

Limited. Resale value for lab grown diamonds is markedly lower than for natural diamonds, and continues to fall as production costs drop. If you are buying an engagement ring as an investment, lab grown is not the right choice. Most people buy one to wear, not to sell.

Should I buy a lab grown diamond engagement ring?

It makes sense if you want a larger or cleaner stone for the same budget. It does not make sense if you are buying for investment, because resale value is low. For most buyers an engagement ring is a piece to wear rather than an asset to sell.

Which gold carat should I choose - 9ct, 14ct or 18ct?

9ct is the most common choice in the UK: it is harder, so it scratches less in daily wear, and it is the most affordable. 18ct gives a richer gold colour and is softer. 14ct sits between the two. All three are hallmarked.
