This exceptional transparent emerald cut color change sapphire weighs 1.39 carats, measuring 7.03 x 5.18 x 3.89 mm, and comes to you from Tanzania through The Natural Sapphire Company. The stone displays a medium intense color intensity that shifts intriguingly depending on lighting, and it has been graded as very very slightly included at eye level, a clarity that is rare for color change material. The emerald cut is a particularly elegant choice for this type of sapphire, with its step facets and broad table that both showcase the stone transparency and reveal the subtle interplay of hues. The excellent polish ensures that light dances smoothly across the facets, maximizing the stone clarity and making the color change easy to read with a natural movement. Most importantly for discerning collectors, this sapphire has no enhancement, preserving its natural state and offering a pure gem experience that is becoming increasingly uncommon on the market.
When comparing this piece to other options, its untreated status and eye level clarity set it apart from the many heat treated or otherwise enhanced sapphires commonly sold. Heat treatment can produce vivid saturated color, but it also changes the original nature of the gem and often reduces long term rarity and value. Color change sapphires that remain completely natural and untreated are among the most sought after by collectors, because they capture geological rarity rather than human intervention. Many color change stones with dramatic shifts are included or opaque, or they are subjected to enhancements to improve visual appeal. This emerald cut 1.39 carat sapphire offers a balance of transparency, natural color dynamics, and top tier craftsmanship, delivering both aesthetic pleasure and a sensible long term value proposition for the investor who prefers genuine natural material.
