0.60 Ct. Green Sapphire from Madagascar

This heart shape green sapphire is a study in precision and natural beauty, weighing 0.60 carat, with dimensions of 5.10 x 5.42 x 2.87 mm, and a mixed brilliant cut that balances scintillation and depth. It is transparent, with a medium intense color intensity that reads as a refined green with subtle blue undertones depending on the light source, and an excellent polish that allows light to dance cleanly across the pavilion and crown facets. The clarity grade is very very slightly included, evaluated at eye level, which for a sapphire of this size means the eye sees a clean field and the minor inclusions do not interrupt brilliance or durability. This sapphire has undergone no enhancement, a fact that significantly increases its appeal to educated buyers who value untreated natural material, and its origin is Madagascar, a locality that has produced a wide range of desirable sapphire colors and that is known for gemstones with both attractive color and good crystallographic integrity. At 0.60 carat the stone is substantial enough to serve as a focal point in a delicate ring or pendant, and the heart shape adds an emotional narrative that will resonate with buyers seeking both beauty and meaning.

The journey of this sapphire from mine to market is a layered story of geology, careful recovery, and skilled craftsmanship. Formed deep within Madagascar s crust under high temperature and pressure, the corundum nucleus grew slowly, incorporating trace elements that produced its green hue as titanium and iron balanced in the crystal lattice. After years locked in hard rock, the gem found release through erosion and transport, eventually ending up in alluvial gravels that artisanal and small scale miners sift. In Madagascar many mining communities rely on hands and simple tools to extract rough material, and stones are then sorted by experienced eyes for potential value. This particular piece was identified for its desirable color and transparency, then sent to a cutter who assessed the rough and chose a mixed brilliant heart shape to maximize weight retention while enhancing fire and life. The cutter controlled facet angles to complement the stone s medium intense color, optimizing pavilion depth to prevent windowing and preserving a high crown to increase sparkle. The polishing stage received special attention to achieve the excellent polish recorded in our lab notes, using progressively finer abrasives to eliminate surface graining and to ensure crisp facet junctions. Throughout this process The Natural Sapphire Company maintained strict provenance documentation and performed multiple checks to confirm that the sapphire was free of enhancements, providing the buyer a transparent chain of custody from Madagascar s alluvial fields to the finished gem you see here.

For an educated buyer this sapphire offers a combination of technical merit and emotional resonance that is difficult to find in treated material or in stones without clear provenance. The lack of enhancement means the color is wholly natural, and the medium intense saturation is well suited to both classic and contemporary settings because it reads as vivid without appearing unnaturally dark. The very very slightly included clarity grade evaluated at eye level ensures the gem will present a clean face up appearance in most mounting styles, and the excellent polish enhances durability at the surface while maximizing brilliance. When considering mounting options, settings that allow light to enter from below, such as semi open or low profile collet settings, will emphasize the mixed brilliant cut s life and will make the heart silhouette more readable at daily viewing distances. This sapphire is ideal for an engagement ring or a meaningful pendant, where the combination of heart shape and natural green color communicates both individuality and provenance. As with all corundum, moderate care is recommended, including avoiding prolonged exposure to ultrasonic cleaners if the mounting includes adhesives, and cleaning with warm soapy water and a soft brush for routine maintenance. At The Natural Sapphire Company we will supply documentation of origin and treatment status, and we can advise on complementary metal choices and setting styles that will protect the girdle and enhance the stone s visual impact. This gem represents an investment in an untreated natural material with a clear, traceable story from Madagascar s geology to a skilled cutter s bench, and finally to a collection or jewelry piece where its natural beauty can be enjoyed for generations.
