The Allison Solitaire Diamond Engagement Ring

A solitaire holds one diamond. That singular focus is the point — and it's been the point for as long as engagement rings have existed.

The Allison is a classic solitaire engagement ring built around the conviction that when one diamond is given the right setting, the right proportion, and nothing to compete with it, the result is a ring of complete and quiet power. The tapered band shapes that conviction into a silhouette — narrowing toward the center, drawing the eye where it belongs. As a simple engagement ring, the Allison treats restraint as a design language. As a diamond solitaire ring, it gives the diamond room to be exactly what it is.

Wear it as the truest expression of a single committed choice. The Allison joins a Lisa Robin tradition of solitaire engagement rings where simplicity is treated as a deliberate design decision rather than the absence of one.

Design Process

The Lisa Robin Engagement Ring Design Experience

How your ring goes from your idea to the finished piece, with clarity at every step.

Online Ordering

Begin your custom engagement ring online, with guidance at each decision. Diamond shape guides, setting comparisons and education pages throughout the site help you understand every choice.

If you would like to personalize your design, place your order at any time. Lisa follows up to refine the details with you before anything is crafted.

Private Design Appointments

For a more collaborative experience, meet with Lisa one-on-one, in the studio or by Zoom. Your design appointment is shaped around you: Lisa guides each decision in real time as your diamond engagement ring takes shape.

Compare diamonds from trusted suppliers around the world through the Lisa Robin Global Diamond Collection.

Review available diamonds by shape, proportions and overall presence, and choose the one that suits your design, your priorities and your budget.

Lisa shows you how each diamond will sit in your setting, so the finished engagement ring feels balanced and intentional.

Natural and lab-grown diamonds are both available, so you can choose what feels right for you.

Before your ring is crafted, you review detailed CAD renderings made with your diamond's exact dimensions.

Multiple views let you see proportions, balance and design details, so you know how your engagement ring will come together before crafting begins.

If you add a wedding ring to the same order, the renderings show each ring on its own and both together, so you can see how they pair.

Once you approve your design, your ring is crafted by hand, made for you.

Your engagement ring is completed in 3 to 4 weeks after design approval.

Choose fully insured shipping or a private pickup at the studio. Lisa stays in touch at every stage, so you always know what comes next.

I loved working with Lisa Robin! It was so easy to create exactly what I wanted. With some minor changes to Lisa's gorgeous styles, I had the perfect wedding ring to coordinate with my Lisa Robin Engagement Ring. Can’t wait to add another ring to my stack.

Frequently Asked Questions about Emerald-Cut Diamond Engagement Rings

Emerald cuts use step-cut facets that emphasize clarity and proportion rather than brilliance. This creates a sleek, hall-of-mirrors effect that feels elegant and understated.

Yes. Their refined geometry and architectural beauty make them ideal for alternative engagement rings that step outside traditional brilliance but still feel timeless.

Because of their elongated shape and broad surface area, emerald cuts often appear larger than other diamonds of the same carat weight.

Because inclusions can be more visible in step-cut designs, a higher clarity grade is often the better choice. The right choice depends on the specific diamond, which we’ll guide you through personally.

The emerald cut’s history dates back to the Art Deco era, making it a natural fit for vintage style engagement rings and retro designs with architectural references.

Solitaires, east west settings, halos, toi et moi rings, and cluster arrangements all complement the emerald cut’s linear beauty. The best choice depends on your personal style and the story you want your ring to tell.

Yes. At Lisa Robin, you can customize your diamond, metal, and setting. Whether you want a classic solitaire or a unique engagement ring design, we guide you through every step to bring your vision to life.
