What Is a Micro (Castell) Set Diamond Setting?

A castell set ring is almost identical to the micro pave setting, with the only distinction being the size of the stones used. Both castell and micro pave settings involve closely setting diamonds to ensure that the prongs or tiny metal beads holding the stones in place are barely visible. This is an ideal choice for those seeking a ring with abundant sparkle, especially if the ring is low set or lacks the desired level of brilliance.

In short: A micro (castell) setting holds small diamonds between tiny tapered prongs cut directly into a raised wall of metal — creating a continuous gleaming band similar to pavé but with stronger structural support. Stones typically range 0.005-0.05ct each. New York's 47th Street specialists hand-cut the castells under magnification, taking 4-6 hours per band. Works best on engagement-ring shoulders and full-eternity bands in 18kt white gold and platinum.

So, what sets apart a micro pave setting from a castell setting? It's straightforward. A micro pave setting involves diamonds smaller than 0.1 carats, typically ranging between 0.01 and 0.05 carats. Your choice between the two depends on personal preference—how you want the diamonds to appear on the ring—and the available space. In some cases, a micro pave setting may be the only feasible option.

This type of setting demands an exceptional level of skill, although modern CAD design has made it somewhat easier in recent years. CAD design ensures effective layout planning on pre-drilled surfaces, leading to a better distribution of diamonds. Nevertheless, mastering this technique may take several years, as acknowledged by most specialists.

One consideration is that this setting may be susceptible to stone loss over time, regardless of the setting's quality. However, with careful wear and avoidance of knocks, this shouldn't be a significant concern. If a stone is lost, simply bring the ring back to us, and we can replace it for you.
