3.61 Ct. Blue Sapphire from Ceylon (Sri Lanka)

At The Natural Sapphire Company we present a rare C.Dunaigre certified Blue, a transparent blue sapphire weighing 3.61 carat, cut to an elegant oval measuring 10.22 by 8.20 by 4.76 mm. This stone displays a vivid color intensity, a mixed brilliant cut, and a clarity graded as very slightly included when evaluated at eye level. The excellent polish and careful faceting highlight the gemological strengths that make this sapphire stand apart from ordinary stones on the market. Originating from Ceylon Sri Lanka, and enhanced by traditional heat treatment to refine color and clarity, this sapphire arrives ready to become a centerpiece in a custom engagement ring or a standout pendant, offering both visual drama and long term value.

What gives this sapphire its unmatched sparkle is the precise interaction of material and cutting geometry. Corundum naturally has a strong ability to bend and return light, and the cutter has used a mixed brilliant motif to amplify that quality. The crown facets are arranged to create controlled dispersion and lively surface scintillation, while the pavilion facets are angled to optimize internal reflection so that light entering the stone is bounced back through the crown rather than leaking out the base. The oval outline concentrates the play of light along the long axis, producing a ribbon of deep, velvety blue at the center with lively flashes around the perimeter. Because the clarity is very slightly included at eye level, light travels through relatively uninterrupted paths, which enhances brightness without introducing distracting spots. The excellent polish further reduces light scattering at the facet junctions, preserving sharp contrasts between light and dark facets and delivering crisp, lively scintillation that is immediately apparent when compared side by side with other sapphires.

Compared with other market offerings this sapphire stands out in three key ways, color, cut, and proportion. Many blue sapphires show good tone but suffer from uneven saturation or a lack of life due to deep, windowing, or poor facet alignment. This Ceylon stone balances vivid color intensity with a clarity that lets color breathe without becoming murky. The mixed brilliant cut is superior to standard step cuts for one simple reason, it offers both depth of color and active light return. While step cuts can emphasize color at the expense of sparkle, and simple brilliant cuts can maximize sparkle but lose some face up color, the mixed brilliant approach used here preserves that deep Ceylon blue while delivering dynamic scintillation. The oval shape also provides a larger face up appearance for the weight than many round counterparts, giving more visible presence without a disproportionate price premium. For buyers comparing options, this stone represents a rare equilibrium between saturated, vivid color and high optical performance.

Beyond optical performance, this sapphire offers tangible value and assurance that make it a superior choice. The C.Dunaigre certification documents its identity and origin, providing transparency that many market stones lack. Heat treatment is disclosed because ethical transparency is central to the purchasing experience at The Natural Sapphire Company, and the applied treatment is the industry standard to enhance clarity and color in a stable, enduring way. For customers seeking investment quality or a meaningful heirloom, the combination of 3.61 carat weight, the favorable dimensions of 10.22 by 8.20 by 4.76 mm, vivid color intensity, and excellent polish creates both aesthetic and intrinsic appeal. In settings, this sapphire will show consistent sparkle from multiple angles due to the careful facet design, and it will pair well with both contemporary and classic mounting styles, maintaining presence and personality without appearing overly dark or flat under normal lighting.

If you are comparing sapphires, consider how many stones sacrifice one attribute to gain another, color for size, brilliance for depth, or clarity for cost. This Ceylon blue sapphire from The Natural Sapphire Company gives you an integrated solution that preserves the advantages of each attribute. The result is a gem with a brilliant personality, a vivid, resilient color, and a cut that transforms the stone into a luminous focal point. For anyone looking to invest in a sapphire that competes with the best available on the market, this 3.61 carat oval C.Dunaigre certified gem delivers a level of sparkle and overall harmony that is difficult to find in mass market pieces.
