3.62 Ct. Blue Sapphire from Ceylon (Sri Lanka)

Imagine a mineral hidden for hundreds of millions of years, locked within the deep, dynamic geology of Sri Lanka, slowly transformed by heat and pressure into a crystalline treasure, with this pear shape sapphire as the final expression of that process. Corundum, the mineral family that produces sapphires, forms where aluminum rich sediments are subjected to regional metamorphism, or where hydrothermal fluids permeate aluminous host rocks, allowing aluminum and oxygen to reorganize into a rigid, hexagonal crystal lattice. Trace amounts of iron and titanium became incorporated into that lattice in precise ratios, producing the deep, saturated blue that characterizes this stone. Over geological time, tectonic forces uplifted and exposed the host formations, and weathering and erosion liberated crystals into alluvial placers where skilled miners of Ceylon collected the rough material. Subsequent human hands carefully selected and cut the crystal to preserve its purity and color, a process that began millions of years after its initial formation. The result is a transparent, vivid blue corundum that carries within its chemistry and structure a record of earth processes, making it more than a gem, but a condensed narrative of geological time.

From a gemological perspective, this sapphire combines several features that informed buyers value, starting with its weight, shape, and precise dimensions. It weighs 3.62 carat, and measures 12.22 by 9.50 by 4.51 mm, fashioned into a pear shape with a mixed brilliant cut that balances color saturation with lively light return. The mixed brilliant cutting style preserves strong face up color while introducing a dynamic scintillation across the crown facets, a particularly effective approach for larger sapphires where both depth of color and brightness are important. Clarity is graded as eye clean, evaluated at eye level, meaning there are no inclusions visible to the unaided eye and the stone presents a clean, uninterrupted field of color and brilliance. The polish has been evaluated as excellent, with crisp facet junctions and a smooth table that maximizes the stone's optical performance. Color intensity is vivid, a highly sought after descriptor for blue sapphires, offering a saturated, pure blue that reads strongly in a variety of lights. This stone has undergone standard heat treatment, a widely accepted and stable enhancement in the trade, applied to improve uniformity of color and to reduce microscopic silk that can cloud the face up appearance, and it is fully disclosed. The origin of this sapphire is Ceylon, Sri Lanka, a provenance associated with a long history of producing attractive, saturated blue sapphires that often display a luminous, velvety quality distinct from stones of other localities.

For the educated buyer seeking both beauty and investment sense, this sapphire from The Natural Sapphire Company represents a compelling combination of size, color, and clarity that is uncommon at the 3.62 carat weight. Eye clean stones with vivid color at this scale are relatively rare, and when paired with excellent polish and a thoughtful mixed brilliant pear cut, the result is a gem that performs beautifully in a variety of high end settings. The pear shape offers elegant versatility for rings and pendants, elongating the finger when mounted vertically and providing a flattering profile in bezel or prong settings, while the measured girdle and 4.51 mm depth create a sleek, low profile that sits comfortably on the hand without sacrificing presence. Heat treatment, as disclosed, is stable and permanent, and is the industry standard for improving color in natural sapphires, accepted by collectors and institutions when fully documented. We recommend settings that allow light to enter the pavilion and reflect within the crown, to take full advantage of the mixed brilliant facets and preserve the sapphire's vivid tone.

At The Natural Sapphire Company we pay close attention to provenance, cutting quality, and full disclosure, and we can provide additional documentation and imagery upon request to support your evaluation. For care, avoid harsh chemicals and sudden temperature extremes, clean gently with warm soapy water and a soft brush, and have a professional check the setting periodically to protect the stone. Whether you are a collector seeking a rare eye clean Ceylon sapphire with vivid color, a designer looking for a striking centerpiece for a bespoke commission, or an investor focused on long term value, this pear shape 3.62 carat sapphire offers a clear, well documented set of attributes that experienced buyers seek. We are happy to discuss independent laboratory reports, mounting options, and bespoke settings to help this gem become a lasting and meaningful part of your collection.
