Natural Teal Green-Blue Sapphires

Natural teal green-blue sapphires feature a unique blend of oceanic green and blue hues, renowned for their incredible hardness and durability (9 on the Mohs scale). Because of their unique color-changing characteristics—appearing greener in sunlight and bluer under indoor lighting—they are highly sought-after alternatives to traditional diamond engagement rings. 

Teal sapphires are prized for their "chameleon" effects and distinct properties: 

• Color Composition & Zoning: Ranging from vibrant greenish-blues to deep inky teals, they often display striking color zoning (visible pockets of different shades like yellow or green within a single stone). 
• Pricing & Value: Prices generally fall between $1,500 and $3,000 per carat depending on the cut, clarity, and treatment (such as heat enhancement), making them often more affordable than pure blue sapphires. 
• Origin: Notable sources include Madagascar and the United States (Montana is famous for its unique natural teal variations)
