1.40 Ct. Yellowish Green Sapphire from Ceylon (Sri Lanka)

From the ancient alluvial fields of Ceylon in Sri Lanka this yellowish green sapphire began its story as a sliver of molten earth shaped by time and pressure deep beneath the surface. For generations miners in this storied land have followed veins and riverbeds, guided by knowledge passed down through families, seeking the rare moments when light will be trapped forever inside corundum. The stone you see now carries that quiet history, a transparent oval that once lay hidden in gravel and sand, then surfaced through the hands of those who know the land and respect its seasons. The color that makes this gem so compelling has its roots in the precise chemistry and cooling within the earth, a dialogue between trace elements and crystal growth that yields a yellowish green tone with a dark color intensity that changes subtly as it meets different kinds of light.

When the rough reached the lapidary, the choice to fashion it into an oval with a mixed brilliant cut was made with both mind and heart. At 1.40 carats the finished gem measures 7.95 x 5.92 x 3.78 mm, a form that balances presence with wearable proportions. The mixed brilliant cut brings together a pavilion designed for depth and sparkle and a crown faceting plan that opens the surface to catch and reflect light, enhancing the stone’s natural fire while maintaining the gentle green warmth that defines its personality. The cutter worked to reveal clarity rather than conceal it, polishing each facet to an excellent finish so that the transparency and internal life of the sapphire can be appreciated at a glance. The clarity grade of very very slightly included evaluated at eye level means that to the naked eye the gem remains clean and luminous, while under magnification the natural fingerprints of its geological past are revealed, adding character and authenticity rather than detracting from its beauty.

This sapphire has been heat treated, a time honored enhancement that stabilizes and intensifies color while preserving the intrinsic durability that makes corundum such a cherished gem. Heat treatment in properly conducted conditions helps to dissolve or alter microscopic inclusions and to bring forward the yellowish green hues, yielding a stone that presents a confident, saturated tone without compromising its structural integrity. The excellent polish complements the mixed brilliant faceting, allowing the surface to play with light and shadow and to show the depth of color even in varied lighting. From the crown you will see flashes of brighter green, while the pavilion will present brooding depths that emphasize the gem’s dark color intensity, creating a dynamic presence whether set alone as a solitaire or combined with other gems in a custom piece.

Durability is where sapphire truly shines, making this gem an ideal companion for daily wear. On the Mohs scale sapphire ranks at 9, second only to diamond, which translates into exceptional resistance to scratches and surface wear during everyday activities. Its toughness is strong enough to endure routine handling, and the heat treatment it has undergone is a stable enhancement that will not fade or compromise the stone under normal conditions. With the oval dimensions of 7.95 x 5.92 x 3.78 mm and the secure outline of a mixed brilliant cut, this sapphire can be confidently placed in settings that protect edges and girdles, such as classic prongs with protective shoulders or a bezel for a sleek contemporary look. For cleaning and care a gentle routine will preserve its beauty, using warm water, mild soap, and a soft brush to remove oils and dust, followed by a gentle pat dry. Avoid exposure to strong acids or abrasives and remove the piece during heavy manual labor or contact sports to prevent hard knocks that could chip the setting or loosen prongs.
