🔧 What it does & how to use

This tool gradually enlarges a ring's internal diameter by working it up a tapered mandrel, tap by tap, until the desired size is reached. It's a simple, low-cost way to resize rings without cutting or soldering, and suits both hobbyists and working jewellers.

• Set up: place the plastic end and base on a flat, stable table.
• Position the ring: slide the ring onto the mandrel until it sits tight.
• Insert the enlarger: push the enlarger through the middle of the ring.
• Tap gently: use a hammer to tap the enlarger, working the ring further along the taper.
• Check size: stretch in small increments, testing fit regularly until the ring reaches the size you need.

⚠️ Please check the ring's material and any gemstones before stretching — soft metals stretch more easily than hard alloys, and stones set close to the shank can be at risk if over-stretched in one go.
