About John: John is a Syzjewelry jeweler and business owner with 13 years of jewelry-design experience. This guide shares the wall thickness and height I work to when a bezel is modelled in CAD.

A bezel wall needs at least 0.45 mm. In practice I run 0.5-0.6 mm for stones under 6 mm and 0.7-0.8 mm for stones of 8-10 mm, with the bezel height at about 70% of the stone's depth.

My notes cover those two size ranges. For a stone between 6 and 8 mm, ask rather than guess.

The numbers I work to

• Bezel wall, absolute minimum: 0.45 mm.
• Stones under 6 mm: 0.5-0.6 mm wall.
• Stones of 8-10 mm: 0.7-0.8 mm wall.
• Bezel height: about 70% of the stone's depth.

Height follows the stone

I set the height as a share of the stone's depth, so a deeper stone gets a taller wall. A flat height figure would be wrong for one stone or the other.

The minimum is the floor

0.45 mm is the floor. The 0.5-0.6 mm and 0.7-0.8 mm figures are what I run in practice.

Using this when you shop

• Match the stone size in millimetres to the setting size on the listing.
• If the listing does not show wall thickness and it matters to you, ask before you order.
• For a stone between 6 and 8 mm, ask.

Figures are ranges from my own bench notes. Actual practice follows each workshop's process card, order requirements and the current standard.

A semi bezel on this page is the setting that says half bezel. Metal covers part of the stone’s edge, and the rest of the edge stays open. A full bezel covers the edge all the way around.

How to choose

• Read the bezel word in the title: full, half, split, channel, or flush.
• Match your stone’s shape and its millimeter size. Carat weight does not tell you the seat size.
• The center stone is included only when that listing says so.

One listing can use more than one of these words. This page is bezel settings. It does not include prong settings.
