Choosing a Band
We want your ring to last forever. Which is why we follow strict tolerances that keep slim bands narrow, but not wimpy, and we carefully hand-finish all bands to a depth of at least 1.6mm. (See this design’s width specs below in Description & Details.)
Customize Your Band
Don’t see the perfect band? We can customize any design so it’s perfect for you. Just reach out to get started.
Pro Tip
Keep your band safe and looking its best: remove before working out, don’t sleep in your rings, and take advantage of Plum’s free annual maintenance that’s included with purchase.
Style
There’s no right or wrong answer here. We only offer classic options, and you can’t go wrong. If you don’t see exactly what you want, reach out to customize.
Band Design
We want your wedding ring to be treasured forever, which is why our bands are crafted with the best alloys and why we follow strict tolerances for beauty and durability. (See this design’s diamond and width specs below in Description & Details.)
Pro Tip
Keep your band safe and looking its best: remove before working out, don’t sleep in your rings, and take advantage of Plum’s free annual maintenance that’s included with purchase.
Showing Off Your Diamond
Our centers are designed for security and aesthetics, to hold your diamond safely in place while letting it sparkle like crazy.
East-West Orientation
(Available with elongated diamond shapes.) A great way to personalize your ring for a unique, modern look is to modify your center diamond so it’s set east-to-west.
Pro Tip
When choosing your metal, opt for a white center setting to keep your diamond bright. Platinum is a great choice, or you can select a two-tone setting. This is where the band is yellow or rose gold and the center is platinum. Choose 18k Yellow & Platinum or 14k Rose & Platinum when selecting your Metal Type for a two-tone setting.
The Center Setting
We design each setting from scratch, to precisely fit your center diamond. Plum center settings are crafted for security and sparkle, to hold your diamond safely in place while letting it shine like crazy.
Securing Your Diamond
Our claw prongs are the opposite of chunky or square and hold your diamond with a graceful point, while Plum bezels are slim yet secure.
Cathedral or No Cathedral
Cathedral settings feature graceful arches that rise from the band, creating a flowing, integrated look that connects beautifully with the center stone.
In contrast, non-cathedral settings allow the center stone to sit more prominently above the band, almost appearing to float—perfect for showcasing your diamond as the star of the show.
A Flush Fit
Many of our settings are thoughtfully designed so that a straight wedding band stacks closely with your engagement ring.
However, low basket and low bezel settings are exceptions—when your diamond sits lower on your finger, a small gap between the rings is natural.
If you’re looking for the perfect wedding band to pair with a low-profile ring, we’re happy to help! Options like contour bands, open bands, or even a custom design can create a beautiful fit. (That said, we don’t mind a little gap—it adds character!)

Your Center Diamond Shape
We couldn’t pick a favorite shape any more than we could pick a favorite child! There’s no right or wrong when choosing the one that’s perfect for you, and if you’d like help, we’re here to assist.
Here’s a handy graphic with Plum’s lineup of diamond shapes—you can see that certain shapes look larger than others for their carat weight.
Choosing a Halo Shape
This comes down to whether you want to gaze at your hand and see a round halo or a slightly squared off halo shape. If you like the idea of having some angles, a Soft Square halo is a great choice because you still get the maximum brilliance of a timeless round diamond, with a little added geometric interest.

Precious Metals
We use recycled gold and responsibly-sourced platinum. Our casters have been turning out the best quality metal alloys for decades and are certified by the Responsible Jewellery Council for sustainability. Plum rings come in high karat gold, platinum, and gold with platinum center prongs (“two tone”).
Gold
We craft yellow and white gold rings in 18k because it has a higher gold content than 14k. If you’d prefer 14k gold instead, we’re happy to accommodate you.
Rose gold rings are crafted in 14k; our gold alloy is a beautiful, rich rose color and it is alloyed to be more durable than alternatives.
Platinum vs. White Gold
Platinum is a pure metal and very rare; it’s hypoallergenic and naturally white, so it does not require plating. A great choice if you’re looking for a low maintenance metal.
Pro Tip
When selecting a rose or yellow gold engagement ring, keep in mind that diamonds reflect the colors around them. To amplify the whiteness and brightness of your diamond — and for an elevated look — consider choosing platinum prongs.
The Side View
We design each setting from scratch, to precisely fit your center diamond. Plum center settings are crafted for security and sparkle, to hold your diamond safely in place while letting it shine like crazy.

Choosing Your Side Shape
All are classic choices, and you can’t go wrong. All of our Three Stone customizations were carefully chosen to be universally flattering with your lab diamond center.
Side Setting Size
This comes down to personal preference. Some like smaller diamonds on the side to help the center look larger by contrast, while other people prefer a look with larger diamonds and more coverage across the finger.
All of our Three Stone customizations were carefully chosen to be universally flattering with a round diamond center.
