Understanding Larimar Grades: AAA vs. Lower-Quality Stones

If you're shopping for Larimar jewelry, you've likely come across terms like AAA-grade, high-quality Larimar, or even commercial-grade stones—but what do these grades really mean? And how can you tell the difference?

Whether you're a first-time buyer or a dedicated collector, understanding how Larimar is graded is essential to making a smart and lasting investment. In this guide, we’ll break down the different Larimar quality grades, what to look for, and how to choose the best stone for your collection or gifting.

What Is Larimar and Why Is It Graded?

Larimar is a rare blue gemstone found only in the Dominican Republic. Its stunning ocean-inspired hues, unique patterns, and limited supply make it a coveted choice for collectors and jewelry lovers alike.

Because every Larimar stone is different, grading helps define quality, value, and visual appeal. Most reputable sellers (like us at Larimarket) categorize Larimar into the following informal but widely recognized tiers:

• AAA Grade (Top Quality)

• AA Grade (Medium-High Quality)

• A or Commercial Grade (Entry-Level Quality)

What Makes AAA Larimar the Best?

AAA Larimar is considered the highest quality available—and for good reason. Here's what sets it apart:

• Color: Rich, vibrant blue—often described as "Caribbean blue" or "volcanic blue."

• Pattern: Strong white marbling or cloud-like swirls. Highly defined and naturally balanced.

• Clarity: Minimal to no inclusions, cracks, or green/gray discoloration.

• Polish: Excellent luster and smooth finish—glows even in soft light.

• Rarity: Less than 10% of mined Larimar meets AAA standards.

When you see a deep blue stone with crisp, white patterns and a glassy polish—it’s likely AAA.

How Does Lower-Grade Larimar Compare?

Lower-grade Larimar (often labeled A or B Grade) can still be beautiful but tends to have:

• Faded or pale blue tones

• Uneven or muddy coloring

• More inclusions or matrix lines (brown or green mineral deposits)

• Minimal marbling or low contrast

• Surface imperfections or lackluster polish

These stones are often used in inexpensive jewelry or beads but may lack the distinct “wow” factor of premium-grade Larimar.

How to Visually Identify Larimar Grades (Even as a Beginner)

If you're new to Larimar, here’s a quick checklist to help evaluate the quality:

 Pro tip: Always view Larimar in natural light and ask for multiple angles or videos from the seller.

Should You Always Buy AAA Larimar?

It depends on your goals:

• For heirloom-quality pieces, gifts, or collectors → Yes. AAA stones offer the best color, clarity, and long-term value.

• For casual wear, stacking, or variety → Mix it up. Lower-grade stones can be budget-friendly and still lovely, especially in layered looks.

Always look for:

• Transparent grading and honest descriptions

• Natural, unfiltered photos and videos

• Expertise in Larimar (not just general gemstones)

• A return policy you can feel good about
