This striking Australian bi-color sapphire captivates with its vivid, saturated golden-yellow body color and a distinctive deeper olive-green zone that sweeps through the upper portion of the stone, creating a dramatic and wholly natural color transition. The contrast between the warm pure yellow and the cooler yellow-green tone is bold and characteristic of fine Australian parti sapphires. At 7.5x6mm the stone has excellent presence, with lively light return through the well-cut oval facets.
Australian sapphires are celebrated for their distinctive parti and bi-color zoning, a natural phenomenon rare in sapphires from any other origin. This stone has been heat treated to stabilize and enhance its color, following the standard and accepted practice for sapphire. At 1.47ct it is an ideal size for a solitaire pendant, an east-west ring, or any design that celebrates individual color character. A truly individual sapphire for a distinctive piece of jewelry.

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 heated, and the color from heating is stable. 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.
