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.

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.

Behind every finished piece is a process that can’t be automated...

It is patience, care, and a deep respect for what each piece represents. Not just objects, but heirlooms, milestones, and stories entrusted to us.

Each step is done by skilled hands that have spent years refining their craft.

From proper stone setting, structural integrity, and meticulous finishings… this is the work that allows fine jewelry to be worn daily and passed down over time.

While technology continues to evolve, the human element remains irreplaceable.

Custom engagement rings, vintage jewelry restoration, and fine jewelry services, all completed in our Georgetown atelier.

Vintage watches carry function, history, and the mark of how they were used.

At Market Street Diamonds, our approach to vintage watch sourcing is intentional. Each piece is selected for its mechanical significance, design integrity, and condition, from purpose-built tool watches to wrist conversions.

Our restoration process is equally considered. Movements are serviced for reliable performance, while original details are preserved wherever possible. Patina, dial integrity, and period correct components remain part of the story.

The result is a collection of vintage luxury watches that can be worn daily, while still holding their historical character.

Explore vintage watches from brands like Breitling, Tudor, Tissot, and Rolex. Each one of a kind. Each with a function that extends beyond timekeeping.

Spring in Washington DC has finally arrived…

And with it, a shift in color, light, and texture 🌞🌸

From diamond earrings to tennis bracelets and bridal rings, each detail is woven into the composition. A study in contrast between natural form and crafted design.
