The note goes in a drawer. The card fades.

But something engraved into the watch he reaches for every morning, that stays.

Because the best gifts aren’t the most expensive. They’re the ones that prove you paid attention.

Laser engraving from $125, complimentary with every Market Street Diamonds purchase.

What sets this ring apart isn’t the diamond.

It’s the silhouette 🥐

This oval diamond engagement ring pairs a classic center stone with sculptural croissant-inspired shoulders that bring movement, texture, and character to the design.

The flowing band creates a distinctive profile while preserving the timeless appeal of a solitaire, offering a fresh take on one of the most beloved engagement ring styles.

Part of our Heritage Collection of lab-grown diamond engagement rings.

Some things you wear. A few you keep.

A Briston isn’t loud about it, the way good design rarely is. A tortoise and stainless case, a strap that softens with the years, a face he’ll glance at a hundred times a day without thinking, and once or twice, think of you.

This Father’s Day, find his in our Give Him Time collection. Fine watches from $400, each one ready to be made personal with a date, his initials, or a few words in your own hand, plus complimentary laser engraving on every purchase.

Time well given.

The best designs don’t start from scratch. They start with a story 🫶

When Jason and Madzi worked with Sydney, the goal wasn’t just to create a custom engagement ring… It was to create something deeply personal.

The final design incorporates diamonds from Madzi’s grandmother’s ring while echoing elements of its original design, connecting generations through a piece made for a new chapter.

A ring that honors the past while becoming part of a new story.

For Father’s Day, we’re helping clients transform watches and jewelry into something deeply personal through custom laser engraving.

A handwritten message. An inside joke. A date that matters.

Using our in-house engraving process, we can engrave almost anything onto a watch or piece of jewelry, creating a permanent reminder of the people and moments that matter most.

The result is more than a gift. It’s a story they’ll carry with them every day.

Engraving starts at $125 and is complimentary with every Market Street Diamonds purchase.

There’s a moment during engagement ring shopping when the conversation shifts.

You stop asking what you should choose and start seeing what feels like you.

Sometimes it happens the second a ring goes on. Sometimes it takes trying on a dozen styles to get there.

Either way, it’s one of our favorite moments to witness 🥹

If you’re beginning your engagement ring search, our team is here to help you explore, compare, and discover what feels right… no pressure, no guesswork.

If engagement ring shopping is on the horizon, send this to your future fiancé as a subtle reminder to schedule the appointment 🫶

Your engagement ring should feel like you…

Emily and Frank worked with Rayna to design a ring that felt thoughtful, personal, and timeless. From the beginning, the goal was to create something that truly reflected Emily and that she would love wearing for years to come.

The final design feels effortlessly wearable while still full of intention, balancing classic elements with details that make it entirely her own.

Every engagement ring begins long before the finished piece…

A sketch. A stone. A proportion adjustment. A CAD model rotated from every angle until the balance feels right.

This ring began with a rare 8.30-carat hexagonal brilliant cut diamond and a vision for something architectural, intentional, and entirely one-of-a-kind.

Designed at our Georgetown atelier, every detail was carefully considered to let the geometry of the diamond remain the focal point while creating a setting built for everyday wear.

The vision is only the beginning.… the craftsmanship is what brings it to life 🤲

Engagement rings available online and in our Georgetown atelier.
