About $400 to $1,800. That's not a hedge - it's a bracket so wide because the variables aren't small. I've quoted both ends of that range in the last six months, and a few jobs went higher. Let me break it down so you know what you're actually paying for.
What drives the cost
The stone price is just the start. A pair of .10 carat single-cut diamonds in a shared-prong setting might cost $200 total for the stones - but the labor to set them adds another $300 to $500, depending on how tight the apertures are and whether the shank needs to be reinforced to carry them.
The heavier lift is when the side stones change the construction of the ring entirely. A solitaire shank is simple: a head, a band, done. Add side stones and you're now running a channel, building seatwork, setting multiple stones in a curved layout, and probably switching from a stamped or prefab head to a custom-cast one. That's where the money goes - not the stones themselves, but the metal and the hours around them.
The breakdown by stone type
Here's what I typically see:
- Small melee diamonds (1.0mm to 1.8mm, G-H color, SI clarity): About $50-$100 per stone for the diamond. Another $80-$120 per stone for setting labor in a shared-prong or micro-pavé layout.
- Full-cut side diamonds (2.0mm and up, each individually prong-set): $150-$400 per stone for the diamond itself, plus $100-$200 per stone for setting. At this size you're paying for grading consistency - the side stones need to match each other and the center, which adds sourcing time.
- Colored gemstones (sapphires, emeralds, rubies): $100-$1,000+ per stone depending on origin and treatment. Setting a 3mm round sapphire is about the same labor as a diamond of that size - maybe $100-$150 per stone - but if the stone is fragile, as emeralds often are, the risk premium shows up in the quote.
- Baguettes or tapered baguettes: $200-$600 per stone for the stone, and $150-$250 per stone for setting. Baguettes are harder to set than rounds because the corners need to be precise or they chip.
The hidden costs most articles skip
First: the shank redesign. Adding side stones to an existing solitaire design often requires thickening the band to support the new stone pockets. That's more gold, more labor, and sometimes a new casting of the entire ring. That alone can run $200-$600.
Second: the setting fee doesn't include the master mold or the CAD work if the ring is being built from scratch. If your side stones are what turn a simple design into a complex one - say, three-stone with tapered baguettes flanking an oval - the CAD revision might add $150-$300 to the job.
Third: rhodium plating, if the ring is white gold. Adding side stones means more metal surface area to plate, and some stones need to be masked. That's $50-$100 on top, usually rolled into a final polishing charge.
When the price surprises people - and when it shouldn't
Last spring a client named Marco came in with a 1.4 carat old European cut he inherited from his grandmother. He wanted two .25 carat round diamonds set on either side, in platinum. The stones were $200 each (good GIA-graded, G/SI, eye-clean). The platinum shank and the setting work came to $1,200. The total: $1,600 for the sides. He'd assumed it would be under $500. I showed him the casting, the platinum cost per gram, and the setting layout on the wax model. He understood. The ring took eight weeks and he still texts me photos of it.
On the other end: I had a woman named Nicole who wanted .06 carat melee set in a micro-pavé channel down each shoulder of a 14k yellow gold band. Eight stones on each side. The labor for the setting was $640. The stones were $320. The carving of the channel was included in the original CAD price. The ring came in at $960 for the sides. She'd budgeted $1,500. She added an engraving.
The flat answer you can take to a jeweler
If you're shopping quotes and you hear $400 to $800 for two small side stones in a simple prong setting on a band that already exists, that's reasonable. If you're starting from scratch with four or more stones, or baguettes, or a curved layout, expect $1,200 to $2,000. If anyone quotes under $300 for multiple stones, ask what you're not getting - thin settings, lower-grade stones, rushed work that'll need re-tipping in three years.
I tell clients to budget for the sides as if they were a separate piece of jewelry. Because they are. Every stone you add is another seat, another prong, another point of failure and another point of beauty. It costs what it costs.
