0.42 Ct. Yellowish Green Sapphire from Madagascar

From the green hills of Madagascar to the careful hands of our master cutters, this transparent 0.42 carat radiant shape yellowish green sapphire tells a story of earth and craftsmanship. Formed over millions of years in metamorphic rock, this gem was discovered in one of Madagascar’s rich alluvial deposits where sapphires of many hues surface after seasonal rains. The rough stone displayed a gentle yellowish green that promised elegance and character, and the decision was made to bring out its best with a radiant cut that enhances both color and brilliance. The finished dimensions are 4.03 by 4.02 by 3.07 mm, the cut exhibits precise facet alignment, the clarity has been graded as very very slightly included at eye level, the color intensity is medium, and the polish is excellent. Importantly, this sapphire has undergone no enhancement, preserving the natural story written into its crystal structure, and at The Natural Sapphire Company we are proud to present it as a genuine, untreated treasure from Madagascar.

The journey from rough to a perfectly faceted gemstone is as much a narrative of human skill as it is of geological time. Our cutter studied the stone under magnification to determine the best orientation to balance weight retention, optical performance, and symmetry. Choosing the radiant cut allowed us to create a square silhouette with softened corners, and a pattern of facets that produces scintillation and depth without sacrificing the delicate yellowish green hue that makes this sapphire unique. The clarity grade of very very slightly included, evaluated at eye level, means that inclusions are minimal and do not detract from the gem’s beauty to the naked eye, while they confirm the natural origin of the stone. The excellent polish gives the pavilion and crown a mirror like finish, so when light enters the stone it refracts and reflects with a lively, welcoming sparkle. Because there has been no enhancement applied to this sapphire, what you see is the stone exactly as nature fashioned it, responsibly sourced and carefully cut.

Visually, this yellowish green sapphire offers an intriguing balance between freshness and refinement. Under natural daylight the stone leans toward a vibrant green with lemon undertones, while in softer, indoor light the yellowish aspect becomes more apparent, creating a versatile color personality that adapts to its surroundings. The radiant cut’s faceting pattern creates a play of light that is especially flattering in small scale, making the gem an ideal candidate for delicate everyday jewelry as well as an exquisite centerpiece for formal pieces. In casual settings the sapphire reads as a fresh, modern accent when set in minimalist bezel or prong styles, pairing beautifully with linen shirts, denim, and sunlit gatherings. For formal occasions the same stone can anchor an elegant halo ring or a refined pendant, where its medium color intensity allows it to stand out without overpowering complementary diamonds or intricate metalwork.

When considering settings and pairings, this sapphire’s compact dimensions and lively color open a wide range of design possibilities. In warm metals such as yellow gold or rose gold, the yellowish notes of the stone are enhanced, producing a harmonious, vintage inspired look. In white metals such as platinum or white gold, the stone takes on a crisp, contemporary air, the green leaning character becoming the focal point against a cool backdrop. For daily wear, a low profile four prong or bezel setting offers both safety and simplicity, while for a statement piece a halo of white diamonds amplifies brilliance and gives the illusion of a larger center stone. At 0.42 carat and 4.03 by 4.02 by 3.07 mm the gem reads as an elegant, wearable size, comfortable on a finger and perfectly scaled for paired earrings or a pendant. Sapphires are second only to diamonds in hardness, so this natural, unenhanced sapphire is well suited to regular wear, and with basic care it will retain its polish and color for a lifetime.

Caring for a natural sapphire is straightforward, and simple maintenance will preserve its beauty for generations. Clean the gem with warm soapy water and a soft brush, rinse thoroughly, and dry with a lint free cloth. Avoid prolonged exposure to harsh chemicals and extreme temperature shifts, and remove jewelry before heavy manual tasks to protect settings from knocks.
