- Choose metal and finger size — platinum, 18K or 14K in white, yellow, or rose.
- The setting is cast to order — every element is proportioned to your exact diamond and finger size.
- A gemologist reviews the diamond before setting, then the finished ring ships from the Los Angeles atelier.
How Custom Engagement Rings Work: Process, Cost, and Timeline
A custom engagement ring is built in two halves: you choose a center diamond, then a setting is cast specifically around that diamond and the wearer's finger size. There is no inventory ring pulled off a shelf — the metal is poured for your stone. Here is exactly how that works, what it costs, and how long it takes.

What can go wrong with a custom engagement ring, and how is it prevented?
Custom engagement ring FAQ
Is a custom ring more expensive than a ready-made one?
Not inherently. You pay for the center diamond and the setting. There is no markup for a finished piece held in inventory.
Can I use my own diamond?
The standard process is choosing a certified diamond and having the setting cast around it. Contact RockHer for other arrangements.
How long does it take?
8–12 business days from order to shipment, made in the Los Angeles atelier.
Can the ring be resized later?
Cast-to-order settings reduce the need for resizing because the band is built to size. Resizing afterward is possible for most plain or partially-paved bands; full eternity-style bands are harder to resize without rework.
