A lot goes into making one single piece of jewellery

There are numerous benefits to hand-made rings, and using the materials David does, discover more  herehere & here.

Every ring is handmade by David using skills he has finely tuned over decades, using tools he has made especially.

Making the band, here are the rollings mills, rolling is a metal forming process in which metal is passed through one or more pairs of rolls to reduce the thickness and to make the thickness uniform.

3

Draw plates, The plate is held securely in a vice or other fixture. Annealed wire is filed at one end to give it an initial taped. The tapered end is inserted into a hole with a final diameter just smaller than it’s current diameter. Special pliers called draw tongs hold the tip of the wire & pull it through, with the aid of wax as a lubricant.

Before and after milling & drawing. A piece of Platinum 6mm square rod, which has been drawn, then milled to produce a piece of 3.3 x 1.9 mm D profile wire, to be made into the shank of a ring, shown here hallmarked.

5

Next David needs to shape the straight piece of metal into a ring, here using half round pliers and strong hands

6

Once the ring is round, David welds the ends together with oxyacetylene, the melting temperature of Platinum is 3,224ºF.

7

Now a complete ring, David makes the ring round, and the correct size using a steel mandrill and a hide mallet

8

The ring is to have a bulb setting with rub-over and grain set diamonds. A platinum setting shown here in the lathe.

9

David makes the setting perfectly round, and ensures the diamond fits exactly in the setting. Still in the lathe, but turned round, the setting is polished, a post created to locate the setting in the band

10

The setting is then soldered to the band, using oxyacetylene, the metal is at red heat.

11

Next David needs to work out then mark the diamond spacing on the ring using dividers. The ring is coated in a special ink to make the marks easier to see.

12

The ring has 79 perfect brilliant cut diamond set in it, the setting 24 plus the main stone. The spacing is worked out and marked in the same way,  all to a tolerance of 0.01mm. 

 

13

After marking out, the holes are drilled. Very steady hands are required to ensure the holes are exactly the correct diameter and angle. Yes the tools are very like those used by dentists !

14

The main diamond is rub-over set. David has made his own tool especially for the task. His training as a scientific & medical instrument maker has provided him with excellent skills for such.

15

David sorts fine brilliant cut diamonds into 0.01mm increments, in lines. The small diamonds in the setting have been placed & set, the middle line in the band are in the process of being set.

16

Small grains of metal hold the diamonds in place. Once all the stones are set, David will spend many hours working with numerous grades of specialist compounds to achieve  a perfect mirror polished finish on the Platinum.

17

The finished ring, the main stone is a natural fancy colour diamond, with white diamonds in the setting and band which are made from platinum.
