A Ring That Reflects Your Story and the Way You Live It
Not sure where to start? That’s completely normal. At Thollot & Co. Jewelers, we’ll walk you through everything; from diamond shapes, settings, custom design, all with a calm, friendly & thoughtful approach that feels more like a conversation between friends rather than a presentation. After all, selecting an engagement ring is a time to celebrate!

There’s Something About Getting Engaged in Colorado
It rarely happens in a ballroom.
It happens at the top of a trail after a quiet hike. On a ski trip where the moment catches you off guard. At sunrise in Boulder. On a weekend in Copper where everything just feels right.
Colorado has a way of making moments feel real; unfiltered, a little adventurous, and deeply personal. And that’s exactly how an engagement should feel.
At Thollot & Co. Jewelers, we’ve had the privilege of being part of thousands of those moments across metro Denver and beyond. What we’ve learned is simple: The ring matters, but how it feels matters more.
How Do You Choose the Right Engagement Ring?
You don’t need to know everything walking in.
You just need the right guidance.
There’s a lot to sort through; diamond shapes, setting styles, natural vs. lab-grown, custom vs. ready-made. It’s easy to overthink it.
Our role is to simplify that for you.
We’ll ask the right questions. We’ll show you what actually matters. And we’ll help you land on something that feels like the two of you, like this moment.
Because today, couples aren’t just buying jewelry. They’re making thoughtful, intentional decisions; and they want to feel confident in the decisions they have made.
Couples from Denver and throughout Colorado trust Thollot & Co. Jewelers for engagement rings because we focus on what matters most – beautiful diamonds, exceptional craftsmanship, and personal service.

Custom Engagement Rings
Designed Around Your Story
Some of the best rings we create at Thollot & Co. are ones that don’t exist yet. They start with a conversation. A sketch. A memory. A place.
Maybe it’s the ridge line where you hiked together. Maybe it’s a vintage ring your grandmother wore. Maybe it’s just a feeling you can’t quite describe.
Our custom design process is built to bring that to life:
- Collaborative design consultations
- CAD renderings so you can see it before it’s made
- In-house craftsmanship from experienced jewelers
For many couples, creating the perfect ring becomes part of the story itself, especially with Thollot’s signature “Pour Your Heart Into It” experience, where you can literally pour the gold that becomes your ring. That’s not something you will soon forget.
Custom design doesn’t necessarily cost more. In many cases, it simply allows you to create exactly what you want. Couples often choose custom engagement rings when they want something distinctive that can’t be found in a display case.

Its very form captures the fire of our Colorado sunsets, the fire of your passion, captured in the cut of your diamond.

Colored Gemstone Engagement Rings
A Little More Personal. A Little Less Expected.
Colorado isn’t exactly a “follow the rules” kind of place. And increasingly, neither are engagement rings.
Sapphires. Emeralds. Rubies; or even a subtle hint of color tucked into a hidden detail.
For some couples, color reflects personality. For others, it reflects a place; a blue that reminds them of hanging lakes, a green tied to summer hikes, something that feels just slightly different and distinctly personal.
Selecting color gemstones or a fancy-colored diamond is about being expressive and intentional. It’s about choosing something that feels like you.

Lab-Grown Engagement Rings
Lab-grown diamonds have become an increasingly popular option for engagement rings. These diamonds are physically, chemically, and visually identical to natural diamonds, but they are man-made in advanced laboratories rather than coming from the earth’s natural processes.
Many couples choose lab-grown diamonds because they offer:
- Larger carat weight for the same budget
- Excellent color and clarity
- Modern technology and sourcing
At Thollot & CO. Jewelers, we carry both natural diamonds and lab-grown diamonds. Compare them side by side and choose the option that feels right for you. Our job is to give you clear, honest information so you can decide with confidence.

Popular Engagement Ring Trends
While classic designs never go out of style, many couples enjoy exploring current engagement ring trends.

Elongated Diamond Shapes
Oval, emerald, marquise, and elongated cushion diamonds are especially popular because they create an elegant, lengthening effect on the finger.

Wide Bands
Bold bands with pavé diamonds or engraved details create a dramatic look.

Ring Stacking
Stackable wedding bands and anniversary bands allow couples to add meaning to their ring over time.

Choosing the Right Metal
Because You’re Actually Going to Live In It
Your engagement ring is not a ring that sits in a drawer. It’s worn hiking. Traveling. Working. Living.
That’s why we focus on metals that balance beauty with durability:
Platinum: Extremely durable, naturally white, and hypoallergenic.
White Gold: Bright and elegant with a modern appearance.
Yellow Gold: Warm and timeless and growing in popularity, yellow gold is especially popular for classic and contemporary styles.
Rose Gold: Soft blush tones with romantic appeal.
Our team will help you choose the metal that best fits your style and lifestyle.
