Rings & Diamonds

Can I customize my ring?

Yes! We are a custom manufacturer at heart and are happy to customize your ring design.

Once we know what customization you’d like, we’ll provide a quote; the cost covers your revised CAD/CAM and any additional metal, diamonds, setting and finishing labor.

When you’re ready, we’ll email a separate invoice with payment link for easy order processing.

All of our rings are already made-to-order, and so customizing with us is a simple way to get EXACTLY what you want!

If you’ve got your heart set on a customized ring, contact us to get started.

What are lab-grown diamonds?

Lab-grown diamonds are also known as man-made or lab-created. The main difference between lab-grown diamonds and mined diamonds is where they come from. Believe it or not, lab diamonds have the same physical and chemical properties as mined diamonds but they’re made under controlled laboratory environments. Learn allll about lab grown diamonds.

All of our lab diamonds come with a unique grading certificate from an independent lab such as IGI (International Gemological Institute), GIA (The Gemological Institute of America), AGI (Accredited Gemological Institute) or GCAL (Gem Certification and Assurance Lab).

How do I choose a center diamond?

Our goal is to help make choosing your lab grown diamond uncomplicated. Once you select your ring design, you'll be prompted to choose your diamond.

Plum's lab grown diamond selection has been curated for quality, and we share expert tips along the way. Of course, you can always contact us for help.

How are your rings made?

By magic! Kidding (sort of). We use a mix of old-school and modern technology that starts with a CAD design and photopolymer prototype. Our proprietary casting methods and precious metal alloys result in the highest quality settings that are hand-set and polished.

Our selection of lab diamonds meets strict criteria for cut, polish, symmetry, color, and clarity. Our manufacturing team only works with high-quality precious metal alloys, and our expert setters hand-finish each ring—all of which go through rigorous quality assurance checks.

What is your production time?

Since all of our rings are custom made-to-order, production times can vary, but our rings typically ship within 3 weeks.

So you always know what's going on with your ring, we'll send email updates as your ring progresses.

I have a vintage stone/diamond/ring—am I able to use that in my ring?

We appreciate how precious heirloom diamonds can be and know that they require extra special care. We are unfortunately unable to work with diamonds, gemstones, or metals that are not provided by Plum.

If you are in or around Chicago, please email hello@plumdiamonds.com, and we'll do our best to provide a referral who may be able to help.

Are your rings environmentally friendly?
