How does the Sierra Pear Blue Diamond differ from the white diamond Sierra?

The setting is the same: a pear center ringed by a halo of round white diamonds with larger round accents at the compass points. The difference is the center: a fancy blue pear-cut diamond rather than a colorless one. The white halo frames the blue and sharpens it by contrast, so the color reads as the focus.

Which metal works best with a blue diamond center?

All four work, and they do different things. White gold and platinum are cool metals that let the blue read at its most saturated and modern. Yellow gold sets a warm metal against a cool center, which makes the blue look deeper by opposition, the boldest of the four. Rose gold is the softest contrast. If you're undecided, we can show you the same center in each during a design appointment.

Are blue diamonds natural or lab grown, and how do I choose one?

The Sierra's blue center is a lab grown blue diamond. Natural blue diamonds are rarely available at engagement ring size, so lab grown is what makes a saturated blue center a practical choice. You choose the carat weight and depth of blue, online or together with us during a design appointment.

Our guided approach to customizing each ring with intention and clarity.

Every Lisa Robin ring is made to order, which means your design can be thoughtfully refined—even when ordering online. Whether you’re adjusting a detail or evolving the design, we guide you through each decision to ensure the final piece feels cohesive and entirely yours.

Design Refinements can be explored after your initial order, with any pricing adjustments clearly outlined and approved before crafting begins.

Refinement options include but are not limited to:

  • Adjusting the width or taper of the band (shank)
  • Modifying or adding side diamonds for additional detail or presence
  • Changing the prong style (claw, round, double prong, etc.)
  • Adjusting the number of prongs for both aesthetic and structure
  • Refining the basket design for a different profile or overall look
  • Selecting your preferred metal type and color
  • Adapting the design to better coordinate with a wedding ring

The Sierra Pear Blue Diamond Halo Engagement Ring

The Sierra Pear Blue Diamond Halo Engagement Ring puts a fancy blue pear-cut diamond at the center of a vintage-style halo. The pear's rounded end and point give the ring a direction on your finger, and a blue center trades the brightness of a colorless diamond for depth.

The Sierra surrounds the blue pear center with a halo of round white diamonds, and at the four compass points larger rounds extend the halo outward. The colorless frame sharpens the blue rather than softening it.

The Sierra is yours if you're drawn to a pear's softness and want it held inside structure, not left as a bare solitaire's unframed point.

Multiple views allow proportions, balance, and design details to be carefully considered—so you can feel confident in how your engagement ring design will come together before crafting begins.

If a wedding ring is selected within the same order, renderings will also show each ring individually and together, helping you understand how they pair and flow as a set.

Once your design is approved, your ring is hand-crafted specifically for you using carefully selected materials and ethically sourced diamonds.

Each ring is a made to order engagement ring, typically completed in approximately three weeks.

You can choose secure, fully insured shipping or private studio pickup. Throughout the process, we remain available to guide you—so you always know what to expect at every stage.

Yes. You can personalize any design online — diamond, metal, and finger size — or book a private design appointment in studio or by Zoom to modify a design or create one from scratch. Lisa guides you through the process and you see renderings of your ring before it is crafted.
Each ring is made to order and ready in approximately 3-4 weeks from the time your design is approved.
Both are real diamonds with identical physical and optical properties. A lab grown diamond is created in a controlled setting and generally lets you reach a larger or higher-quality diamond for the same budget. A natural diamond forms over geologic time. The choice is yours.
It depends on how you want the diamond to sit on your hand. A solitaire puts the diamond first; a halo makes it read larger; a hidden halo adds sparkle only seen from the side; a bezel gives the most secure, modern line; a cluster or twist makes a more individual statement. Because every design is hand-crafted to your diamond, you can pair most styles with most shapes.
All four — 14K yellow, white, and rose gold, and platinum — wear well for daily use. White gold and platinum give the brightest, most neutral backdrop for a diamond. Yellow and rose gold add warmth around the center. The best choice is the tone you want to see on your hand.
Yes. If you love a design as it is, you can select your diamond, metal color, and finger size and complete your order online. An appointment is only needed if you want to modify a design or create something fully custom.

Yes. Every Lisa Robin engagement ring carries a lifetime craftsmanship warranty.
