Custom Designed Engagement Rings

At James Porter & Son we can provide a bespoke design service for just about any piece of jewellery. Our unique history means we can source ring mounts and gemstones from all over the world and our generations of quality craftsmanship enables us to create new pieces from old and forgotten heirlooms.


Choose Your Setting

Your custom made ring can be designed in a wide range of settings from solitaire or diamond set shoulders, to contemporary claw and cluster settings. Simply choose your setting in platinum, 9ct or 18ct gold. Browse our extensive range of engagement rings for inspiration.


Select Your Gemstone

Take a look at our collection and choose a stone that matches your style. Or, If you’ve already found the perfect stone, we can match it with your chosen setting. If you need help with choosing a stone, read our guides on diamond buying and birthstones.


Tell us your ideas

There are so many different design elements to an engagement ring. Gives us a call and we’ll talk through your ideas, review your designs and provide more information on the process and cost involved. If your ideas are complex we can produce digital 3D design file which will be used for modelling.

The Crafting Process

For a completely bespoke engagement ring, the process typically works as follows:


When you have finalised your design we then create the wax model of the item from a 3D rendering or by hand. It is then created in metal through the casting process before stone set and polished for you.


Once returned, the ring is set by hand with your chosen gemstone/gemstones by one of our expert jewellers in the setting corresponding to your design.


When the ring is assembled it is then sent away to an assay office to be hallmarked which certificates the ring’s fineness, year of production and identifies the company that produced the ring with a stamp or laser engraving on the inside of the band. Find out more about hallmarking in our guide to hallmarks.

Finishing Touches

To complete the process, the ring is then engraved (if requested) and then polished by hand once more, packaged in one of our presentation boxes and either delivered to your door or available for collection in our glasgow showroom.


If diamonds aren't your style, we also hand pick our coloured gemstones for those who love a pop of colour or something more unique! We can also source coloured gemstones to match with existing jewellery items.

Frequently asked questions

How long does the bespoke design process take?

This all depends on the finished design, but on average 4-6 weeks start to finish. For ‘shaped to fit’ rings it can take around 3-4 weeks. For the more complex designs which require drawings, wax models or cad cam images we can usually provide accurate prices and timescales within a week, and will need another 5-6 weeks for the items to be crafted.

Can you remount or unmount stones from your range?

We can mount/unmount or remount stones into any setting and metal of your choosing from our entire collection. So, whatever you are looking for, we can help. If you’ve found the perfect diamond or just got your heart set on a certain setting, or even if you’ve found the perfect ring but want to swap the stone.

Can I use gemstones or diamonds that I already own?

Absolutely, using a setting or gemstones that you already own, our jewellers can assemble your bespoke piece. You’ll need to provide as much information about the stones or setting as possible or alternatively send it to us to work with.
