7.72 Ct. Color Change Sapphire from Madagascar

This piece is a rare and substantial GIA certified Color Change sapphire weighing 7.72 carat, presented in a classic round shape with precise dimensions of 11.79 by 11.58 by 7.15 mm, a mixed brilliant cut, and a transparency that allows light to move cleanly through the stone. The gem displays vivid color intensity and has been evaluated as eye clean when inspected at normal viewing distance, a clarity characteristic that significantly increases visual appeal and market value. The excellent polish and the mixed brilliant faceting have been executed to enhance both brilliance and the stone s ability to exhibit color change under different lighting conditions. This sapphire is heat treated, a stable and widely accepted enhancement, and originates from Madagascar, an increasingly important source for high quality sapphires, including notable examples of color change material. The GIA report that accompanies the gem provides independent verification of these attributes, giving the educated buyer a documented record of authenticity and quality.

From a gemological perspective the features of this sapphire are particularly compelling for a discerning collector or client seeking both beauty and technical quality. The mixed brilliant cut combines a precision brilliant cut crown with a modified pavilion designed to balance light return and color saturation, a deliberate choice for sapphires that show pleochroism and color change. The eye clean clarity grade recorded at eye level means that the stone requires no inclusion masking in a jewelry setting, allowing the full effect of the vivid color and color change phenomenon to be appreciated without distraction. The measured dimensions and 7.72 carat weight make this sapphire large enough to command presence in a single stone ring or pendant, while still being practical for skilled setting work. Heat treatment is disclosed, and this common enhancement improves color stability and consistency without compromising long term durability, a factor well understood and accepted in the market when properly documented.

For the educated buyer this sapphire represents both an aesthetic and a technical proposition that justifies its place in a serious collection or as the centerpiece of a bespoke commission. Color change sapphires are prized because the optical phenomenon itself is intrinsically rare, and a strong, vivid color shift contributes directly to both desirability and value. The rich, bold color of this gem acts as a symbol of personal power and distinction, drawing attention and conveying refinement, while the documented origin from Madagascar situates it within a known geological context that collectors appreciate. Practical considerations for setting include choosing a mounting that allows light to reach the pavilion and crown, and selecting metal color and design to complement the stone s cool to warm shift under daylight and incandescent lighting. At The Natural Sapphire Company we provide the GIA certification, full disclosure of enhancement and origin, and hands on support for custom design choices, ensuring that a buyer acquires not only a visually exceptional gem but also transparent provenance and expert guidance.
