0.57 Ct. Blue Sapphire from Madagascar

This exquisite transparent blue sapphire from The Natural Sapphire Company weighs 0.57 carat, and is cut into a classic oval measuring 6.00 x 4.12 x 2.69 mm. The mixed brilliant cut combines a faceted crown that enhances scintillation with a well proportioned pavilion that promotes depth of color, producing a lively balance of brilliance and saturated hue. The gem displays vivid color intensity, a highly desirable level of saturation that reads as rich blue across a variety of lighting conditions, and is finished with an excellent polish that allows clean light return and crisp facet junctions. Importantly, this sapphire has not undergone any enhancement, a characteristic that sets it apart in the market where heat treatment is common, and its origin is Madagascar, a source increasingly celebrated for producing stones with bright, modern blue tones and strong clarity potential.

From a gemological grading perspective this sapphire presents as slightly included when evaluated at eye level, which means that under normal viewing conditions there are minor internal features that do not significantly interrupt the flow of color or light. Slightly included is a practical and often preferred clarity range for natural colored gemstones, because it indicates natural formation and origin without compromising overall beauty or structural integrity. Sapphires are corundum with a hardness of 9 on the Mohs scale, and this specimen benefits from that intrinsic toughness, which makes it very suitable for daily wear in rings, pendants, or earrings. The combination of excellent polish and durable material ensures long term wearability, while its oval proportions and mixed brilliant faceting optimize the stone for traditional ring settings, halo arrangements, or a refined solitaire design, offering flexibility for bespoke jewelry work.

When we compare this Madagascar sapphire to historically famous sapphires, the contrasts illuminate its unique appeal. The Star of India is renowned for its exceptional size and star phenomenon, and the Logan Sapphire is celebrated for its museum scale and deep velvety blue, while royal jewels such as the Stuart Sapphire carry provenance and ceremonial history. Those stones are remarkable for reasons of scale, rarity of variety, or historical importance. By contrast, this 0.57 carat oval excels in areas that many collectors and informed buyers prize today, namely vivid, untreated color, and clean optical performance in a wearable size. Untreated sapphires with vivid saturation are comparatively rare and are increasingly sought after by connoisseurs who value natural state and traceable origin. Madagascar has risen in recent decades as a productive and high quality source that frequently yields lively, saturated blues that differ from the classic cornflower tones associated with Kashmir and from the deeper, sometimes more velvety hues seen in historic Burmese examples. This means that a gemstone like this one sits in a sweet spot between historic character and contemporary desirability, offering natural beauty with practical wearability.

At The Natural Sapphire Company we place emphasis on full transparency about origin, treatment status, and the specific attributes that determine a gem rank and value. This sapphire has been evaluated for color, clarity, cut, and polish, and its no enhancement status adds distinct value among educated buyers who understand the premium associated with untreated material. For those considering this gem as an investment or as a meaningful piece of personal jewelry, the combination of vivid color intensity, excellent polish, and natural origin from Madagascar makes it an attractive option. We can advise on complementary settings that will maximize its visual impact, for example choosing a setting that allows light to enter the pavilion for the most dynamic color return, or a complementary metal and mount that frame the oval shape without overpowering its natural tone. We also provide guidance on care, recommending routine gentle cleaning and sensible setting choices to preserve the stone integrity.
