This 0.59ct heated blue sapphire oval cabochon presents a deep navy body color with a vivid, concentrated blue highlight that shimmers across the polished dome, creating a dramatic interplay of light and depth on its glossy curved surface. The smooth, high-polish finish accentuates the stone's dark, lustrous base, making the bright blue luminescence appear to float within the interior of the gem like a captured sky.
From Madagascar, this sapphire has been heat treated to deepen its rich blue color, and the cabochon cut is perfectly suited to showcasing its tonal depth and glossy, reflective character. Oval cabochons carry a timeless appeal and lend themselves beautifully to rings, pendants, and earrings with bezel settings that frame the smooth dome to maximum effect. A bold yet understated piece of genuine natural sapphire in a classic form.
Natural blue sapphire cabochon, September birthstone - sold loose.

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 brush, then rinse and dry with a soft cloth. Skip ultrasonic and steam cleaners: cabochons usually contain fine inclusions or fissures that vibration and heat can open.
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.
