A client brought us two loose sapphires, one from her mother's ring and one bought loose online. They looked the same in a drawer, but the moment she held them to her ear one was clearly bluer. That is the first truth of bespoke gemstone earrings: stone matching is half the job, and it does not show up on a sketch. The other half is balance, because a drop that looks elegant on a screen can swing or catch on a shoulder by lunchtime.
Start with the stones, not the silhouette
We lay the matched pair on a grey card under north-facing light and photograph them next to a ruler. If the colour, weight, or cut mismatch is more than a few points, we tell the client before drawing anything. For a pair of matched stones this is standard practice; for a single family stone paired with a loose stone, the atelier will often suggest a near-match rather than a perfect match, because chasing a twin of an uncertified stone drives cost without visible benefit. Our notes on birthstone and gemstone colour pairing cover the palette questions most clients ask first.
Choose the silhouette against the face, not against the page
Earrings are worn against skin, hair, and neckline, so a drawing on A4 lies. We use a face cutout to scale the drop length against the jawline: under 20 mm is a stud or small hoop, 20 to 35 mm is a day drop, and over 40 mm is evening wear. Width matters as much as length. A hoop that is 2 mm wide reads light; the same diameter at 4 mm wide reads heavy. Compare our hoop versus drop settings guide for the trade-offs. The back choice is separate: surgical-steel posts for sensitive ears, lever backs for drops over 20 mm, and hooks only for lightweight pairs.
Why we cut a sample before casting gold
For any pair over a certain budget, we 3D-print a resin sample in the exact size and hang it on the client. This is not theatre. A drop that swings against the jaw when the head turns is a ring-tone in real life, and a post that tilts under stone weight will tilt forever. The sample lets us shorten the basket, widen the post, or swap the hook before the metal is poured. We also use the sample to check the karat weight of the chosen alloy, because 14k and 18k earring posts bend at different loads and the post gauge is set in the CAD.
Build in a service margin
Earrings get lost, one at a time. A bespoke pair that cannot be remade as a single is a future problem. We cast both earrings from the same wax tree so the metal grain matches, and we keep a resin vault of the CAD for ten years so a single replacement is a one-cast job. Retail partners on our white-label programme can pass this on as a service promise. Read about the sketch-to-wax step on pendants to see how the same vault practice applies to neckwear.
Photographing the pair before it leaves the bench
Every bespoke earring pair is photographed on a neutral grey card under north-facing light before dispatch. The client receives the photos with the work order, so there is a record of what the pair looked like on day one. This matters if one earring is lost in five years and needs to be matched; we can compare the replacement against the original photo rather than guessing from memory. For trade clients, the same photos are used for the white-label product sheet, so your retail listings show the actual pair rather than a generic stock image.
FAQ
Can you pair a family stone with a new stone?
Yes, and we do it often. We source a near-match in cut and colour rather than a certified twin, because the ear sees the pair from 30 cm away, not from a loupe. We will show you three loose candidates under the same light before you choose.
How long does a custom earring pair take?
Four to six weeks for a stud or small hoop. A drop with a resin sample fitting adds one to two weeks. If the stones need sourcing, add the time it takes to match them, which we quote separately.
Are custom earrings heavier than ready-made ones?
Not if the basket is hollowed. We keep solid gold only at the post and the seat; the drop itself is hollow-cast to keep the ear comfortable through a full day. Weight is stated on the work order so there are no surprises on the scale.
What metal is safest for sensitive ears?
Titanium or 18k gold posts are the standard. Avoid sterling silver posts for clients who react to nickel, because silver alloys can release trace nickel under the EU REACH nickel directive limits on prolonged skin contact. We confirm the post alloy in writing on every order.
Have a pair of loose stones, or a single stone to match? Send photos under natural light and we will lay out the matching options. We will sketch two silhouettes against a face cutout, quote the resin sample, and only cast once both of you have hung the pair. Trade retailers: our earring white-label pack includes the post-alloy checklist so your sales team can answer sensitive-ear questions on the spot.
