The color is a vivid, clean medium to cornflower blue with excellent saturation and brightness, producing a lively, cheerful tone that catches the light from every angle. The heart cut has been executed with precise symmetry and excellent proportions, with the lobes well-balanced and the point sharp and well-defined at 5.7x5mm. A genuinely appealing piece for anyone seeking a natural blue sapphire with personality and heart.
Australian sapphires are known for their good color and reliable natural quality, and this bright blue example demonstrates the clean, vivid hues that this origin can produce.

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.
