This elegantly elongated unheated Madagascar sapphire is faceted in a distinctly narrow oval measuring 6x3.8mm, producing a sophisticated, slender profile that brings to mind a marquise-adjacent silhouette with the gentle curves of an oval. The color is a cool, steely blue-gray with a greenish undertone, showing a subtle parti character as the stone shifts between cool aqua-teal and warm olive-green zones across the narrow face. Some natural inclusions are present consistent with the SI grade. The elongated proportions make this a genuinely unusual stone that stands apart from standard round or oval sapphires.
Madagascar produces a wide variety of unheated parti sapphires with complex natural color combinations, and this slender oval captures that complexity in an unusual elongated format. This stone is fully unheated and untreated, preserving its natural multi-tonal character without enhancement. At 6x3.8mm and 0.70ct it is a distinctive choice for a sleek pendant, a narrow bezel ring, or an earring design where an elongated, natural blue-green sapphire with a refined, unusual profile is the design goal.

About sapphire
Sapphire is corundum in every color except red. At 9 on the Mohs scale it is second only to diamond, and it is also very tough with no cleavage, so it rarely chips or splits when knocked. Together that makes it one of the most durable gemstones for everyday wear, rings included.
Cleaning
Warm water, a drop of mild dish soap and a soft toothbrush are all you need. Brush behind the stone too, where dust and skin oils collect, then rinse and dry with a soft cloth. Ultrasonic and steam cleaners are usually fine for a faceted sapphire, but skip them if the stone has fissures that reach the surface.
Wear and storage
Sapphire is very hard, so it can scratch softer gemstones stored with it. Only diamond can scratch it, so keep it apart from diamonds and store it on its own in a gem jar or a soft pouch.
For your jeweler
This sapphire is untreated. Sapphire handles normal setting, re-tipping and polishing well. If the stone has fissures that reach the surface, keep it out of direct torch flame and acid pickle.
