Diamonds are equally spaced approximately 0.10 mm apart.

Bead prongs are proportionally sized, consistently rounded and smooth so the ring is comfortable to wear.

Shank thickness is substantial enough to support the bead-set diamonds securely for normal wear.

To maintain shank strength, there are no openings or drill holes beneath the settings. The bearings support the diamonds above the shank surface to allow for easier cleaning.

Bead contact on crowns ranges between 30% and 40%, and beads – even split beads – are ample for proper setting and stone security.

Each bearing is precisely fitted to the stone size, and diamonds are seated securely.

It shouldn’t be difficult, costly or time consuming to maintain or alter a ring.

Shanks shouldn’t go out of round during vigorous physical activity.

The diamond setting in this shank is a different style to the ring shown above, but follows the same criteria for precise bearings, shank thickness and amount of platinum covering the stones.
