How To Make Your Own Engagement RingS

Matt Katz is the fiancé every DIY girl dreams of. Here he explains how he painstakingly constructed a gorgeous engagement ring: bending the band, setting the gem, and polishing it all off. Think of it as "I Do-It-Yourself."

This project will take around 7 years of preparation and 42 hours of labor. Choose your inspiration wisely, then make sure to work with a professional for guidance, troubleshooting, advice and assistance. [1]

Gather your materials. In our case we will be using recycled white gold, a few flecks of rose gold and a Moissanite [2] gemstone.

Making the band

Anneal the long bar with an oxy-propane torch to make it more pliable. Once you've annealed it, take it to the bending machine and work it into a circle.

Once the bar is bent into a circle, place the circle on an anvil with the crack at the top. Hit the ends gently with a small hammer to fold them in on themselves. There will still be a small V shaped notch.

To close the notch, use a fine jeweler's saw to cut through the very middle of the notch. A few more bangs on the ends and they should close up.

Close and round the band

Now solder the band closed. Cover the band with flux paste. This flux paste keeps the ring from being discolored by oxidation, etc. during the annealing process. Clamp the ring in a helper and then put a chip of white gold solder on the crack. Use a torch to heat the band until it begins to glow, heating evenly all over. As soon as the solder liquefies, capillary action should draw it into the crack. Immediately take the heat away. Quench the ring and put it back in the heated pickle[3] to dissolve the flux.

This is the time to round out the ring. Put it on a mandrel to check the size. Hammer with a leather hammer until the ring is circular and the correct size.

File away at the surface of the ring to get rid of any oxidation.

Now this is a single formed band. Some wedding bands end here and just go to being rounded and polished. This engagement ring is much more complicated.

Making the gem setting

To form a smooth transition to the gem setting, take a leftover waste section of the bar, roll it out to thin it. Then bend it on the bending machine so that the arc matches the outside arc of the ring. Hammer at it on a mandrel to thin out the ends.

Paint the ring and the arc with flux, then wire them together. Solder the two pieces together to form one.

Time to make the gem setting. Use the flat piece of white gold bar and roll it into a loop. Put the loop in a setting punch – in this case an oval one. The setting punch has an oval punch that matches – this presses the gold into a nice oval tapered cup. The ring needs a place for this cup to sit. Use a fine jeweler's saw to cut out a wedge from the ring and then grind away with a dremel-style tool till the ends of the ring match the sides of the cup. Finish with a half round file to ensure a smooth fit.

Solder them together.

Now it is time to smooth out the transition from the ring to the setting. This will take forever and is done with a dremel tool for the course work and is finished with a file. Finally, fill in the concave section of the transition with chips of gold. For this ring, use rose gold chips. Clamp the ring at an angle when heating so that the rose gold falls into the right spots of the ring. This part must be done quickly or the bottom of the ring will heat too much and the rose gold on the underside will drip off.

With the rose gold blazes in the setting transition done, shape and grind the ring. Remove material from the sides to thing them for comfort. Round off all of the edges. Curve the inside of the gem setting so it doesn't grate or rub against a very important finger. Begin polishing the band and setting. The rest of the polishing will take place after the gem is set.

Setting the gem

Cover the band in thermoset plastic and secure it in a ball clamp.[4] Now use a dremel tool to carve a thin seat in the setting cup. It should be deep enough to let the gem sit securely, but not so deep that it will scratch the finger.

With a jeweler's saw, cut away a symmetrical rhomboid to expose a floating setting – this means the gem is sitting only on the raised seat and light can go through the sides of the stone. With a small hammer and chisel, tap the edges over to keep the gem secure against the seat. Go very slowly. A wrong tap could chip the gem. Examine the setting with a loupe after every few taps to make sure the gem is level.

Polish

Drop the ring and thermoplastic into hot water and peel off the plastic gunk. Buff the ring with increasingly finer abrasive and papers. Thoroughly wash the ring to remove any grit or abrasive. Hold the ring only with soft strips of leather and buff it against what looks like the world's fastest shoe polisher. Take pictures to eventually show this beautiful ring to friends near and far.
