About All About Gemstones

All About Gemstones is an independent gemstone encyclopedia and education site. Gems are surrounded by jargon, marketing, and myth, and most people simply want a clear, accurate explanation of what a stone is and how to buy and care for it. That is what we set out to provide.

What we cover

• Encyclopedia: in-depth profiles of individual gemstones with their gemological properties, treatments, and care.
• Birthstones: the complete month-by-month chart, modern and traditional.
• Buying Guides: how to judge color and clarity, understand treatments, and identify gems.
• Gem Care: hardness, toughness, wearability, and safe cleaning.

Our standards

We ground our articles in established gemology and the guidance of bodies such as the Gemological Institute of America (GIA) and the wider gem trade. We flag figures and practices that change over time, such as treatment norms and birthstone-list revisions. Our content is general education, not an appraisal or professional, financial, or legal advice.
