❓ Frequently Asked Questions
What is a gemstone?
A mineral or organic material valued for beauty, rarity, color, and durability, and cut or polished for use in jewelry.
What are common gemstone families or types?
Well-known groups include diamonds (carbon); the corundum family (ruby and sapphire); the beryl family (emerald, aquamarine); quartz varieties (amethyst, citrine); plus opal, turquoise, jade, and garnet.
What is the difference between precious and semi-precious gemstones?
Historically, diamonds, rubies, sapphires, and emeralds were called precious; others were semi-precious. Today, value is judged by color, clarity, cut, carat, and rarity, so the terms are less predictive.
How do gemstones form?
Most form deep underground as minerals crystallize under heat and pressure; some are organic (pearls) or form from silica-rich solutions (opal).
How can you tell if a gemstone is natural or synthetic?
Natural stones often contain tiny inclusions; synthetic stones may show distinct growth patterns. Lab reports from a gemologist can confirm origin.
