Side stone engagement rings: elegant, balanced, and enduringly popular

A side stone ring has a dominant centre stone flanked by smaller accent stones. A trilogy ring has three stones of equal or near-equal status — there is no single dominant stone. In a side stone ring, the flanking stones are typically 30–60% of the width of the centre stone. In a trilogy, all three stones are of similar visual weight.

Tapered and straight baguettes work with almost any centre stone but are particularly effective alongside emerald, Asscher, and princess cuts where the rectangular geometry continues across the ring. Trillions suit round, cushion, and oval centres. Half moons work best with round and cushion centres. Round brilliants are universally compatible. The compatibility section on this page covers all eight shapes in detail.

Yes, as closely as possible. Because side stones are set symmetrically and viewed together, mismatches in colour, cut quality, or size are more noticeable than they would be in pavé or melee work. We source matched pairs as part of the commission process, not as an additional service. GIA and IGI grading reports are available for larger side stones on request.

In most cases, yes. Side stone rings typically have a lower profile than halo rings, and a straight wedding band will sit close to the engagement ring without a significant gap. If the side stones extend to the point where they create an obstacle, a shaped or contoured wedding band is the cleanest solution. This is easiest to plan when both pieces are commissioned together.

Yes. Most side stone configurations are suitable for everyday wear. Baguette and channel-set side stones are among the lowest-snag options in fine jewellery. Prong-set shaped side stones — trillions, pears, or shields — require slightly more care as the prongs can loosen over time. An annual check by a jeweller is sufficient for most designs.

It depends on the shape. Step-cut side stones — baguettes, trapezoids, shields — show inclusions more readily than brilliant-cut shapes because their long, open facets act as windows into the stone. For step-cut side stones, VS2 or better is a reasonable guideline. For brilliant-cut side stones such as round brilliants or trillions, SI1 can be eye-clean in smaller sizes. We advise on clarity at the stone selection stage based on the specific shape and size involved.

A bespoke side stone ring starts from £1,200 at À Vie Diamonds. The centre stone accounts for the majority of the cost. The side stones themselves add relatively little compared to the equivalent halo commission — a matched pair of tapered baguettes or round brilliants typically adds £150–£500 to the overall price, depending on shape, size, and quality. Most side stone commissions at À Vie fall in the £2,000–£5,000 range.

Sometimes. Whether side stones can be retrofitted depends on how the original band was constructed — specifically whether the shoulders have enough metal and width to accommodate a setting without compromising the structural integrity of the ring. This is something our team can assess from photographs and measurements. In most cases, if the original ring was made as a solitaire with a straight plain band, there are options. We will give you an honest assessment before any work is agreed.
