A castell set ring is virtually identical to the micro pave setting, with the only difference being the size of the stones used. A castell setting and a micro pave setting refer to one whereby the diamonds are set closely together to ensure that the prongs or tiny metal beads holding the stones in place are barely visible. This is the perfect option for those who are looking for a ring that provides them with a lot of sparkle. It is also recommended if your ring is low set or does not have as much sparkle as you envisioned.

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. Hatton Garden 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 is the difference between a micro pave setting and a castell setting? It is simple. A micro pave setting refers to one whereby the diamonds are smaller than 0.1 carats. For most micro pave set rings, the diamonds will be between 0.01 and 0.05 carats. When you choose between the two, it largely comes down to your own personal preference, i.e. how you want the diamonds to appear on the ring, as well as the space that is available. With some rings, a micro pave setting is the only feasible option.

This type of setting is one that requires an exceptional amount of setting skill, however it has become somewhat easier over the past few years thanks to modern CAD design. This ensures the pre-drilled surfaces are laid out effectively, which leads to a better distribution of the diamonds. Nevertheless, most specialists will admit that it takes a number of years to perfect the technique.

One thing you do need to be mindful of is that this setting can be susceptible to stone loss over time, irrespective of the setting’s quality. Nevertheless, if you do avoid knocks and are careful when wearing the ring this is not something you should have to worry about. If you do lose a stone, simply bring the ring back to us and we can replace it for you.
