Antique Style Bluish Green Sapphire Ring 6.62 Ct., 14K Yellow Gold

This ring centers a transparent C.Dunaigre certified Blue Green sapphire, a striking 6.62 carat emerald cut gem with precise dimensions of 11.08 x 9.69 x 6.04 mm, cut in a classic step cut that emphasizes broad, luminous planes. The sapphire exhibits vivid color saturation and an eye clean clarity grade as evaluated at eye level, paired with an excellent polish that enhances its table and step facets. The stone is heat treated, a stable and widely accepted enhancement for sapphires, and its documented origin is Madagascar, a source known for producing richly colored, well formed sapphires with attractive greenish blue tones. The gem is fully set in 18K yellow gold, the warm gold tone harmonizing with the bluish green color to create a traditional yet distinctive presentation. The C.Dunaigre certificate accompanies this sapphire, providing independent verification of the stone characteristics, treatment, and origin, a key factor for buyers who place value on provenance and transparent disclosure.

From a gemological perspective the emerald cut and step cutting style are important for how this sapphire presents to the eye, the broad flat facets create a hall of mirrors effect that emphasizes the gem color and clarity rather than the scintillation commonly seen in brilliant cuts. In a stone with eye clean clarity, this cut allows the vivid bluish green hue to read consistently across the table, and the excellent polish ensures that light transitions are smooth, minimizing surface abrasion and maximizing face up appeal. The reported measurements and proportions produce a substantial presence on the finger without excessive depth loss, which is important for maintaining both weight and visible spread. Heat treatment in sapphires is a routine and stable enhancement that improves color and clarity, and disclosure of this treatment is part of responsible gem trading. Madagascar origin is meaningful to collectors and connoisseurs, as regional geological conditions influence trace element chemistry, and these signatures are reflected in the depth and nuance of the bluish green color seen here.

When comparing this natural, certified Madagascar sapphire to lab grown alternatives, several technical and market distinctions become relevant to an educated buyer. Lab grown sapphires are chemically and physically sapphire, they are corundum with the same basic hardness and refractive properties, and they can achieve very attractive colors and exceptional clarity at a lower cost. Technically, the optical performance can be comparable, and in practical terms a lab grown stone may offer a larger size or a very pure clarity for the same budget. However, natural sapphires display growth features, inclusions, and trace element patterns that are unique to their geological history, and these features are part of what defines rarity and collectible value. A C.Dunaigre certified natural sapphire carries documented origin and treatment status, and collectors and investors often value verifiable natural provenance. In the gem lab, natural stones from Madagascar show trace element fingerprints that differ from synthetic growth conditions, and these differences can be identified with standard gemological testing. From a market perspective, natural stones, especially those with clear certification and desirable color and clarity, tend to retain or appreciate in value more reliably than synthetics, although the latter offer clear advantages for buyers prioritizing cost or flawless clarity.

For the buyer who values authenticity, documented origin, and the subtle complexities of natural color, this C.Dunaigre certified Blue Green sapphire ring represents both aesthetic distinction and geological pedigree. Set in solid 18K yellow gold, the ring is designed for durability and daily wear, and the protective prong setting with a supportive gallery balances security with an open design that allows light to interact with the step cut. Care for this piece is straightforward, regular gentle cleaning with warm soapy water and a soft brush will maintain the polish and brilliance, and routine inspections for prong wear will preserve the setting integrity.
