1.85 Ct. Greenish Blue Sapphire from Tanzania

From the moment this sapphire first revealed itself in the ancient, alluvial gravels of Tanzania, it began a journey both geological and human, a story that The Natural Sapphire Company is proud to tell. Carved over millions of years under heat and pressure, this transparent 1.85 carat cushion shape sapphire measures 6.97 by 6.29 by 4.43 millimeters, and it carries a greenish blue hue that immediately sets it apart. Our cutters chose a mixed brilliant cut to marry the cushion silhouette with facets that intensify depth and sparkle. With a clarity grade of very slightly included, evaluated at eye level, and an excellent polish, the gem presents with a clean window into its crystalline past, unmarred by enhancement, preserving the stone as nature intended. The provenance of Tanzania lends both geological distinction and narrative richness, a reminder of the landscape and hands that brought this rare piece to light.

What makes this sapphire rare is not only its provenance and purity, but the uncommon pairing of size and color. Greenish blue sapphires of intense saturation are far less common than classic cornflower or deep blue varieties, and to find one at a near two carat weight in a well-proportioned cushion is exceptional. Many sapphires exhibit either stronger blue or overt green tones, but this gem balances the two with an intense color intensity that reads differently under changing light, from a velvety teal in shade to a luminous oceanic blue in direct light. In the marketplace, specimens with this precise combination of weight, tone, clarity, and untreated status are infrequent, making it a distinctive choice for someone seeking a gemstone that feels personal and singular rather than ubiquitous.

At The Natural Sapphire Company we honor that rarity by crafting a narrative around each stone, helping you imagine its passage from Tanzanian riverbeds to your jewellery setting. The cutter’s decision to preserve weight while opening the stone’s face through a mixed brilliant cut was deliberate, intended to showcase both color and brilliance, and to create a wearable focal point that flatters a variety of mountings. For a collector or an engaged couple looking for something beyond the ordinary, this cushion greenish blue sapphire offers both provenance and personality, a conversation piece rooted in earth and elevated by careful human artistry.
