0.50 Ct. Bi Color Sapphire from Madagascar

This heart shaped bi color sapphire began its story deep within the mineral rich soils of Madagascar, where small scale miners carefully recover crystals from river gravels and alluvial deposits. At The Natural Sapphire Company we work directly with these communities and our sourcing practices prioritize fair pay, safe working conditions, and environmental stewardship, so this stone is more than beautiful, it is responsibly sourced. Unenhanced and naturally transparent, this half carat gem carries the honest trace of its origin, and when you hold it you are holding a piece of Madagascar translated by human hands into a refined symbol of nature. The narrative of the land remains visible in its subtle color zoning, and that story is preserved because no heat or other enhancement has altered its original character.

Our master cutter shaped this sapphire into a 0.50 carat heart, measuring 4.34 x 4.53 x 3.17 mm, cutting a mixed brilliant pattern to maximize both sparkle and the unique bi color presence. The polish is excellent, giving the table and pavilion a lively mirror finish, and the clarity has been graded as very slightly included when evaluated at eye level, a testament to its natural integrity. Medium intense color intensity allows the gem to flash both blue and green with yellowish hints depending on the angle and light, making it a truly chameleon like companion for jewelry that moves with the wearer. Because the stone is unenhanced, collectors and conscious consumers can appreciate its authentic geological story, rather than a treated facade.

As a conscious collector you are choosing a gem that aligns with mindful values, you are choosing traceability, minimal environmental impact, and a transparent supply chain. This heart shape bi color sapphire translates those values into a wearable object of meaning, perfect for a bespoke engagement piece, a delicate pendant, or a ring that celebrates individuality and ethical luxury. The Natural Sapphire Company stands behind its provenance and craftsmanship, and will help you imagine a setting that showcases the gem while preserving its story. Owning this sapphire is not only owning a beautiful stone, it is partnering with a company and a community that value people and planet as much as the gem itself.
