0.84 Ct. Andalusite from Madagascar

This transparent 0.84 carat emerald cut andalusite measures 7.04 x 4.49 x 3.25 mm, and presents a sophisticated brownish green hue with medium color intensity. The classic emerald cut has been executed to emphasize the stone clarity and linear elegance, creating broad facet planes that display color and internal character in a calm and controlled way. At eye level the clarity grade is very very slightly included, a designation that indicates only the smallest natural inclusions are visible to a trained observer under normal viewing, and that these do not interrupt the visual flow or durability of the gem. The polish is excellent, which means the facets were finished to an exceptionally smooth surface during cutting, maximizing light return and ensuring crisp facet junctions. There has been no enhancement to alter the color or clarity, so what you see is the natural material as it formed in Madagascar, a provenance that collectors value for traceability and geological interest.

From a gemological perspective this andalusite offers attributes that appeal to educated buyers who assess both aesthetic and scientific merit. Andalusite is known for strong pleochroism, the ability to show different colors when viewed from different directions, and the brownish green body color of this specimen will shift subtly depending on orientation under light, creating a dynamic but understated personality in finished jewelry. The emerald cut is particularly sympathetic to stones with fine clarity and pleochroic behavior, because its long rectangular facets reveal color zoning and internal features in an orderly fashion, rather than scattering light in random flashes. With a Mohs hardness in the range commonly reported for andalusite, the stone is sufficiently durable for daily wear with careful setting design, and the absence of treatment significantly enhances long term value because it preserves the stone in its original state. For buyers comparing natural gemstones, an unenhanced andalusite of this size and presentation from Madagascar is a notable offering, combining visual appeal, geological interest, and straightforward grading.

When considering creation of a piece intended to be a family heirloom, the combination of natural origin, stable color, and fine craftsmanship embodied in this gem is important. An emerald cut andalusite with excellent polish and only very very slight inclusions will sit quietly and confidently in classic settings such as a bezel with protective gallery, a low profile four prong mount with reinforced corners, or a custom design that protects the stone while showcasing its rectangular geometry. Because the gem is unenhanced no special concerns arise from heat or irradiation treatments, and normal care such as gentle cleaning with warm soapy water, avoidance of harsh chemicals, and periodic inspection of the mounting will preserve its condition. We recommend an archival certificate and photographic record to travel with the piece, providing future generations with documented provenance and grading, which is increasingly important in maintaining financial and sentimental value across decades.

At The Natural Gemstone Company we emphasize provenance and transparency, and this Madagascar andalusite is presented with the factual grading details that collectors and designers rely on. Stones that are natural and untreated have a different market trajectory than treated material, because they retain their original mineral chemistry and optical properties, factors that connoisseurs and institutional buyers respect. Commissioning a bespoke setting that complements the stone geometry, pairing the gem with precious metals that will patinate gracefully, and including professional appraisal and secure storage guidance will ensure this andalusite can be passed down as a generational heirloom. Beyond monetary considerations, this gem carries a narrative of origin, craftsmanship, and responsible sourcing, qualities that transform a beautiful object into a meaningful legacy piece for family and future owners.
