When choosing the perfect Celtic wedding ring, it's important to remember that the design is steeped in tradition and meaning.  I suggest considering the following:

1. The knotwork design: The intricate knotwork is a defining feature of Celtic rings and symbolizes the intertwining of two lives. Look for a ring with a design that speaks to you and your partner.

2. The metal: Celtic rings are typically made of precious metals such as gold, silver or platinum. Consider which metal you prefer and whether you want it to be white, yellow, or rose-gold. Or even a mixture of these colours.

3. The width: Celtic rings come in a variety of widths, from thin bands to wider, more substantial rings. Consider your personal style and the size of your fingers when choosing the width.

4. The symbolism: Many Celtic rings feature symbols such as the trinity knot, representing the Holy Trinity, or the Claddagh, which represents love, loyalty, and friendship. Consider which symbols hold special meaning for you and your partner.

5. The craftsmanship: Look for a ring that has been expertly crafted, with a smooth finish and precise detailing. A well-made ring will last a lifetime and become a cherished symbol of your love.

Ultimately, the perfect Irish Celtic wedding ring is one that speaks to you and your partner. Take your time, consider the options, and choose a ring that you'll be proud to wear for the rest of your life.

Oh, and just to confuse you further, there is always an option to get something bespoke. What I mean is, completely new and original and crafted just for you.
