The mission is simple, we need to show how to convert ring setting from “4 prong” ring to a “6 prong”. Many people might be wondering if this is even possible or what the benefits or drawbacks might be for each prong style. One of the main reasons to opt for a 6 prong style would be for security. Simply put, a 6 prong setting is going to hold a diamond more securely than it’s 4 prong counterpart.
Most people wear their engagement rings daily, and as a result these rings will be subject to the abuse of everyday “wear and tear.” It is not terribly uncommon for the prongs of a ring to be bent out of place as they sustain impact with another object. When this happens the center stone has a much better chance of staying in place if there are 6 prongs protecting it rather than 4.
Proponents of the 4 prong head usually like the way they can see a lot more of their diamond, as a 6 prong mounting generally covers the center stone a bit more. It’s important to note that even when a 4 prong head sustains a heavy impact, the center stone still has a good chance of staying in the ring. This is especially true if the head is platinum, which is a very durable metal.
For those people who want the extra piece of mind of a 6 prong setting, or just like how they look in general, there is definitely a way to make it happen!
Let’s dive in.
Removing the 4 prong setting
The first thing that needs to be done to covert a 4 prong ring setting into a 6 prong setting is to remove the existing head. If a stone is already set into the ring, it will be removed beforehand. For this example the ring setting was brand new and had never held a stone before.
In order to remove the head, the ring is placed in a soldering clamp and turned upside down. At this point the base of the head is slowly heated up by the goldsmith’s hand-torch. Once the solder that is holding in the head in places reaches “flowing” temperature, the head is pulled down and out of the ring mounting with tweezers.
6 Prong setting replacement
Once the old head has been removed from the ring mounting, you can see the leftover solder where the old head had once been.
The 6 prong replacement setting is made to fit the center stones size.
Soldering the new 6 prong setting
Once the new head is in position a torch is used yet again, this time to flow the existing solder that was on the ring. This secures the head in place.
A grinding wheel is used on the inside of the ring to make sure the plane between the new head and the ring mounting is nice and smooth.
At this juncture a polishing brush is used to clean up the solder and discoloration between the prongs.
Setting the diamond
Now that the new 6 prong setting is in place it’s time to set the diamond. A setting bur is used to cut the “seats” where the diamond will sit inside of the prongs.
The seats are cut evenly in each prong to allow the stone to be set nice and straight.
Once the diamond is resting in the seats in the prongs, stone-setting pliers are used to pull each one of the prongs individually over the stone. This creates the pressure necessary to ensure the diamond will be remain secure in the ring mounting.
The Finished Product
Here is the completed 4 to 6 prong head conversion! There are multiple benefits to choosing a six prong head over a four, but the greatest and most obvious will always be for the added security.
