A Guide to Plus-Sized Engagement Rings and Wedding Rings

What are Plus Size Rings?

We create some rings to fit larger finger sizes that fall above the average finger sizes available. Many jewellers accommodate regular sizes. As a result, little attention is given to buyers looking for bigger ring sizes.

Plus Size Wedding Rings

Most large-size wedding rings created at Serendipity Diamonds are sized above Z. Contact us if you cannot see your size available. We create the biggest wedding rings through our bespoke design service. Before any work commences, we provide clients with detailed quotes.

Visit our ring size conversion chart to understand better how sizes convert. We are always happy to work with either UK or US-size systems. At the same time, enjoy help from our perfect ring size service available to ensure the best fit with any engagement ring, wedding ring or eternity ring.

What are Z+ size rings?

For every size above Z, a (+) symbol and number are assigned to denote an increase in size—for example, Z, Z+1, Z+2, Z+3 etc. We can create Z+ ring sizes to order in most precious metals. We create Z+ sizes for engagement and wedding rings for men and women.

Typically, we create any size Z engagement rings by bespoke design. Owing to the large band size, we often CAD design the band to the exact finger size to avoid stretching a ring. By stretching a smaller band, the shank often becomes thin and distorted compared to the original design. 

What is the largest wedding ring we have created?

The tickled pink ring created in a larger finger size.

Over the last decade, we have created many large rings. The largest we created was a wedding ring measuring size Z+8. This is by far the very largest ring we have created to date.

Consider the size of your gemstone.

When it comes to a plus-size engagement ring, consider the diamond or gemstone size. 

Avoid small stone sizes. A large band demands a bigger stone size to retain the proportions. Set with a 0.25-carat diamond, or 0.30-carat diamond, a large band tends to dwarf the stone. For this reason, we recommend a much larger diamond. 

Alternatively, choose a cluster with a bigger show of diamonds. Or, choose a different gemstone. For example, a large Aquamarine will be far less costly than a big diamond.

Are plus size engagement rings and wedding rings more expensive?

Expect to pay a little more for any ring with a larger-than-average band due to the additional precious metal required for the larger finger size. 

At the same time, a much larger diamond or gemstone could cost much more than a smaller size. For this reason, we provide Moissanite and Lab-grown diamond alternatives. Both suggestions provide a way to maximise the gemstone size at a lower cost than a natural diamond.

Lab-grown diamond engagement rings cost approximately half the price of a natural diamond equivalent. For this reason, lab-created diamonds make a popular choice for bigger finger sizes when clients look to maximise the size of their diamonds.

Large wedding rings can be more expensive owing to the extra precious metal weight. However, two suggestions will help to reduce the cost.

Firstly, consider a lighter-profile wedding ring. In fact, most wedding rings come in light, medium and heavyweight options depending on the thickness of each option. A light profile contains less metal and will cost less. Conversely, a wide plus-size wedding ring in a medium or heavy weight will cost much more.

Alternatively, choose a non-precious metal. We create many big-size wedding rings made from Titanium. Titanium is a cost-effective metal choice that is perfect for large finger sizes.

How we create a bespoke plus-size ring

Many of our plus-size rings are crafted individually. In addition, our bespoke design service ensures the perfect finger size and design. Finally, our remodelling service offers a way to set existing gemstones into new jewellery items.

Bubble rings worn as plus-size engagement rings.

Diamond bubble rings make a perfect alternative to traditional engagement rings for plus-size fingers. Bubble rings spread a set of diamonds across three bands. Styles are well-suited for larger hands. At the same time, we occasionally make shaped wedding rings to fit bubble ring styles.

How to wear an inherited plus-size ring

Some clients face a dilemma when they inherit a ring from a family member far too large to wear. Due to decorative detail on many rings, size changes can be difficult. For this reason, we recommend clients wear the ring on a chain as a necklace design. This works well for plain, patterned, and even diamond set rings unsuitable for size adjustments.
