The Sierra Pear Morganite Halo Engagement Ring

The Sierra is a pear-shaped morganite inside a halo that points outward at four directions. The pear cut carries the lyricism; the marquise compass accents add a structural counterweight.

The Sierra cradles a pear-cut morganite in a white diamond halo with larger rounds at the compass points — a frame bright enough to give the pale blush something to read against.

Morganite's blush comes from a trace of manganese in the beryl — where morganite gets its color.

How does the Sierra differ from a typical pear-shaped engagement ring?

Most pear-shaped engagement rings frame the stone with a continuous halo of round accent diamonds. The Sierra adds a structural counterweight: at the compass points around the halo, marquise diamonds angle outward, creating both softness and structure in the same setting.

Why a pear cut rather than another shape for the Sierra?

The pear cut combines a rounded end and a pointed end, giving the setting both lyrical curve and directional pull. The Sierra's compass points echo that directional quality at four angles around the stone, meeting the pear's own asymmetry with structured geometry.

When does a marquise-accented morganite engagement ring make sense?

Marquise diamonds carry direction in a way that round accents don't — their pointed tips create movement and angular geometry. A marquise-accented morganite engagement ring like the Sierra frames the morganite with leaf-like or directional structure rather than concentric brilliance.

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

Pear and Compass, Curve Meeting Point

A pear cut is asymmetric by nature — one rounded end, one pointed. The Sierra answers that asymmetry with halo geometry that points in four directions of its own.

The morganite at the center carries the rest of the design's color responsibility. Morganites come in a remarkable range — blush pink through peach to the rarer salmon and deep peach of fine specimens. A colored gemstone engagement ring with a morganite center is as much about which morganite as about which setting: a blush reads soft against rose gold, a peach glows against yellow gold, a deep salmon reads warm against white gold. Morganite is softer than sapphire (7.5-8 Mohs), which makes the protective setting style here important — bezels and halos protect the stone from everyday wear. Most couples come to a morganite engagement ring expecting one color and leave open to the range.

On the hand, the Sierra reads both lyrical and dynamic — the pear's curve sits against the directional pull of the marquise compass points. The Sierra joins a Lisa Robin tradition of pear shape and halo engagement rings designed for couples who want softness and structure together.

Settings in this collection start at $2,095. Paired with a 1 carat lab grown diamond center, a starting engagement ring is approximately $2,995.

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.
