The production of your wedding rings"""

Golden craft meets state-of-the-art technology"

The alloy

From an alloy to a ring blank

First the bars are casted from the very hot, liquid metal.

The thickness of the bars is then reduced by repeated rolling. This condenses the material while preparing it for the later wear and tear of a wedding ring.

Once the final thickness has been reached, the ring blank is punched out with great force. This is the highest quality way to produce wedding rings. By punching out the complete ring, there is no need for a soldering joint later.

Then, the interaction of manual and machine processing of the ring continues.

Our ring shanks have an unusual degree of hardness thanks to our special hardening processes. The hardness is measured and expressed in Vickers (HV).

The ring takes shape

Setting the stones

Our jewel setters need a steady hand and great sensitivity when they set the diamonds.

At acredo you have a wide range of settings and stones. Brilliant-cut, princess, baguette or heart-shaped diamonds - they don’t only have to be held safely, they must also harmonise perfectly with the ring shank.

A rub over stone is placed in a recess that has usually been pre-drilled in the ring shank. The complete material is rotated.

The miracle crown holds the stone with 4 grains that are cut from the precious metal. This setting looks square and is suitable for both single stones and diamond bands.

Another popular setting for diamond bands is the channel setting. Stones are set next to one another without a gap in-between; the channel is usually pre-milled. The stones are only held at the top and bottom and appear to be floating.

Personal engravings

Every piece of jewelry becomes absolutely unique when engraved. Modern laser technology means acredo can provide any kind of engraving from the classical name and date to free drawings.

We have specialists who implement your engraving ideas. Once your rings have been manufactured in our factory, we turn your template into reality.

Each engraving is precision work. The ring must be positioned exactly before the laser begins its work. Concentration and dexterity are indispensable for this.
