This 4.4mm round cabochon from Madagascar presents a deep, pure royal blue color through its smooth, polished dome, with a vivid blue brightness that glows warmly from within the stone. The rich, saturated royal blue tone gives this cabochon a classic, gemmy sapphire character that is more intensely colored than many teal-toned cabochons. Natural inclusions at SI clarity are enclosed within the dome and add to its earth-grown authenticity.
Royal blue cabochon sapphires from Madagascar are prized for their smooth, luminous presentation of color, a classic format that has been used in fine jewelry for centuries. This specimen has been heat treated to enhance its vivid blue. At 0.62ct and 4.4mm, it makes a beautiful bezel-set stone for rings, pendants, and earrings, suiting a wide range of settings from vintage-inspired to contemporary designs.

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.
