1.59 Ct. Greenish Blue Sapphire from Madagascar

This listing describes a single, transparent 1.59 carat fancy shape greenish blue sapphire, offered by The Natural Sapphire Company. The stone measures 10.42 x 6.61 x 4.20 mm, and it has been fashioned with a precise step cut that emphasizes color and clarity. The gem carries an evaluated clarity grade of very slightly included at eye level, and it benefits from an excellent polish that enhances surface brilliance and faceting definition. Color intensity is described as intense, delivering a saturated greenish blue hue that reads as lively and deep in a range of light conditions. The sapphire has undergone standard heat treatment to refine color and clarity, and its documented origin is Madagascar, a source known for producing stones with strong, appealing tones and fine crystallographic structure.

Durability characteristics make this sapphire particularly well suited to daily wear in jewelry. As a corundum, sapphire registers a nine on the Mohs hardness scale, second only to diamond, which provides excellent resistance to scratching from most materials encountered in everyday use. Corundum also has favorable toughness for faceted stones, meaning it resists chipping and cracking when properly set and handled with reasonable care. Unlike gemstones with pronounced cleavage planes, sapphire lacks easy cleavage, reducing the likelihood of catastrophic fracture from normal knocks or impacts. The heat treatment recorded for this stone is a stable, conventional enhancement that does not compromise the structural integrity of the corundum, and it is effectively permanent under normal wear conditions. For routine cleaning we recommend warm water, a mild detergent, and a soft brush to remove routine oils and residues, and professional inspection of the mounting periodically to confirm secure settings. Ultrasonic and steam cleaning are generally acceptable for well-cut, heat-treated sapphires that do not show surface-reaching fractures, but we advise confirming the setting and the stone condition with a jeweler prior to using these methods.

The step cut and very slightly included clarity combine to create an elegant visual character that emphasizes broad, parallel facets and a refined play of light, rather than the scattered brilliance of a brilliant cut. Step cuts tend to display color and clarity in a more architectural manner, offering clear, broad flashes and a sophisticated, understated appearance that is particularly complementary to classic and modern jewelry designs. Given the 10.42 x 6.61 mm dimensions, the stone presents a strong presence on a finger as a solitaire or as the center stone in a three-stone or halo setting, while its 4.20 mm depth maintains good proportions for secure bezel or prong mounts. For daily wear, protective mounting styles such as low-profile bezels or secure multi-prong settings reduce exposure of the pavilion and girdle to hard knocks, while allowing the intense greenish blue color to remain visible and protected. Regular maintenance, including periodic tightening of prongs and professional cleaning, will preserve the excellent polish and visual depth of color for many years.

This sapphire from Madagascar exemplifies the balance of visual quality and physical durability that clients often seek for everyday jewelry. The very slightly included clarity grade at eye level means the inclusions are minimal and do not detract from the gem s overall appearance, while the excellent polish and intense color intensity ensure a refined presentation in finished pieces. We at The Natural Sapphire Company document the enhancement and origin to provide transparent information about the stone s history and treatment, and to assist in appropriate care recommendations. If you plan to set this gem for regular daily use, consider a mounting that protects the girdle and corners, and arrange for a professional inspection after any significant impact. With proper mounting and routine care, this greenish blue step cut sapphire will deliver lasting beauty and dependable wearability as a prominent element of your jewelry collection.
