Your cart is empty.Ideal For Everyone: This Rathburn Ring Stretcher is ideal for both beginners as well as expert jewelers to increase the size of a ring. Notes: (1) Not to be used for stone-set rings. (2) Before using you should anneal your ring. (3) Some rings with weak solder joints, and some cast rings (casting causes metal to be more porous) can break when stretched. (4) You have to make sure you use ring stretchers with plain ring bands only. (5) A light coat of oil is applied to the stretcher to avoid Oxidation. (6) Do not use Titanium, Tungsten, or Stainless Steel. These metals are delicate and will break. Keep in Mind: Inspect for any solder joints that may break apart when stretching. You may need to anneal to soften the ring to afford the expansion of the metal. Generally, this tool fixture will not expand more than 1 finger size. Specification: Material: Steel Application Type: Ring Enlarging Ring Size Capacity: 6 Or Larger Finger Size Steps on Collet Holder: 7 Overall Length: 6-1/2" with base Weight: 9.59 Ounces (271.88 grams) Product Dimensions: 5.8 x 1.2 x 1.2 inches (14.7 x 3 x 3.3 cm) Package Content: Tapered Pin, Mandrel with Nylon Base.

Over the last 47 years my fingers got a bit fatter. Could not comfortably slip on or remove my ring.In about 5 minutes, I stretched my gold wedding band to fit my ring finger perfectly. I used a plastic hammer and a bench vise to hold the mandrel while tapping the inner shaft loose after each 'stretch'. I did about 3 or 4 'stretches' to get it just right. Go carefully and try as you go. You don't want to make it too large.

Bought to try to stretch my wife's wedding rind as the local jewelers wouldn't do it (ring with band).I heated the ring until blood red with my MAP torch (while holding it with tweezers) and used a hammer to strike the wedge-plunger.Left to cool down a bit, and then used a punch from the other side to remove the plunger and release the ring.Took baby steps and tried for fit each time.Took 5 or 6 rounds (check for fit, heat up, place in the tool, expand a little bit, leave to cool) and it fit very well at a bit over 1 size bigger (from 6 to 7+).The ring is about 5 mm wide an d1 mm thick 18K.After stretching it needed some polish because of the torch.Tools used: - MegaCast Metal Ring Stretcher Rathburn 6-1/2 Inches, - MAP torch, - 250 gram hammer, - tweezers, - and a sturdy heat resisting surface (tiled floor, good thing as I dropped the red hot ring once).No damage on ring or the stretcher/plunger and even the laser engraving on the inside of the ring survived.Over all, simple and easy to use tool, I would recommend to anyone willing to try.Just keep in mind not to go overboard as the ring can break.

Easy to set up and use - for years my wedding band was uncomfortably tight so left it in door. Local jewelry sire quoted $75.00/ring and would take 2 days to pick back up. With the ring expander I was able to get my wedding ring to fit perfectly and 3 small expansions to insure I had it just right - highly recommend this tool!

Needed to stretch my wedding band that is white gold one size up. Never used one of these before so was very careful to start by next smashing it with a hammer. I began with a wood mallet. Didn't seem to be changing at all because there's no way to measure how much it expands without disassembling the whole thing as you go. Wasn't changing size at all so I switched to another hammer and again was very careful about how hard I tapped. Didn't seem to be changing size again. Tapped a little firmer and the next thing I know it split the ring. Well now it fits! 😬😳 I don't know what else I could have done differently to not damage the ring. The other big complaint was that when you drive the tapered shaft into the sizer it is extremely difficult to get it out. I would have thought it came with something to reverse punch it out. I ended up taking a long screwdriver and tapping it till it popped out. Construction material is quality. Step sections are good. I don't know if I would think about using it again on any ring even if I thought it was softer metal just because I don't want to take the chance of damaging it like I did my wedding ring. White gold should stretch fairly easily. Disappointed

This is a good tool for $15. It functions well but you should polish it a little on the cut edges and use a plastic wrap to reduce the marking on the inside of the ring. I would recommend some oil on the pin and not driving the pin too far in on each stretching.

Works just like they say, I would have given 5 stars if they had something to help get the rod out.

Product requires a metal mandrel to hammer the ring off, which it does not include for some reason. Neither does it come with proper instructions to use the product. I tried lubing, heating and hammering the opposite end as the instructions on this products images insist, but it didn’t work. My only solution was to use a screw driver as a mandrel and hammer the opposite end until the ring eventually came off. Save your money and mind and buy another ring resizer on amazon that actually gives you the necessary tools and instructions to use their product

Paid a little extra for this higher grade steel tool. Worked as described on two gold wedding bands that needed 3/4 of a size stretch. Took a few firm hits on a solid surface. Did not anneal metal first and still worked well. This product will last for many years and many uses.

I don't know if the seller understands what the components involved are for. The Nylon rest that comes with the ring stretcher is a vital component and it's incomplete.The stretcher is supposed to sit partly inside the nylon rest and the center of the rest has a hole for the metal rod while you're sizing.The issue is, the Nylon rest doesn't have the cutout as it should so the stretcher can rest partly inside it TO HOLD IT IN PLACE. It's pointless to have a hole in the Nylon rest if the rod doesn't reach all the way down into it to hold the stretcher in place. The only way this happens is if someone hammered the rod as far as it would go, which also defeats the purpose of the stretcher. Even then, you would have to use a hard surface to hammer the metal rod down far enough, then line up the rod and hole and HOPE you can hammer the rod the rest of the way through without missing and destroying the nylon rest altogether.If you search for the REAL stretchers these are trying to mimic, the nylon rest shows correctly and has a seat where the stretcher sits INSIDE.Second issue is the metal rod doesn't seem to be fully compatible with the stretcher. They do not fit well together but this is the least of the two by far.It can still be used but not as it's recommended and not without possibility of causing an injury. This is unsafe.
