Precious Gemstones & Their Origins

Diamond:

These are formed deep within the Earth's mantle under extreme heat and pressure and are brought to the surface through volcanic eruptions. Major diamond-producing countries include Botswana, Russia, Canada, Australia, and South Africa.

  • Ancient Origins: Diamonds were first mined in India over 4,000 years ago.
  • Formation Deep Below Earth: They form about 100 miles beneath the Earth's surface and are brought closer to the surface through volcanic eruptions.
  • Hardest Natural Substance: Diamonds are the hardest natural material on Earth, making them ideal for use in jewelry and cutting tools.
  • Billions of Years Old: Most diamonds found today are between 1 and 3.5 billion years old.
  • Unique Like Fingerprints: No two diamonds are exactly alike; each one has unique characteristics.
  • Conductors of Heat: Diamonds are excellent conductors of heat and are used in various industrial applications.
  • Valuable for Industrial Use: Beyond jewelry, diamonds are highly valued in industry for cutting, grinding, and drilling.
  • Color Variety: While most diamonds are clear, they can come in various colors, including blue, green, pink, and yellow, due to impurities and structural defects.
  • Birthstones: Diamonds are the birthstone for April and are believed to bring strength and courage to those who wear them.

Each source is known for producing sapphires with distinct hues and qualities. Sapphires can be found colours such as pink, green, orange, yellow and red with varying tones of each.

Turquoise:

Turquoise is primarily found in arid regions. Significant sources include Iran (Persian Turquoise), the Southwestern United States, particularly in Arizona and New Mexico, and China.

Peridot:
