Non-Frequently Asked Questions About Stones to Carats

Questions nobody should ask - but someone did.

  • At 12 stone (381,018 carats) and an average gem diamond price of $5,000 per carat, you would be worth approximately 1.9 billion dollars if made entirely of diamond. This exceeds the GDP of several small nations and would make you the most valuable object on the planet. Alas, human tissue trades at considerably lower rates.

  • The world's largest gem collections weigh far less than one stone. The entire British Crown Jewels collection, including every diamond, ruby, sapphire, and emerald, weighs a few kilograms at most, well under one stone. Gemstones are valuable precisely because they are rare and small.

  • Carats sound far more romantic, even though the number is much larger. 'You are worth 350,000 carats to me' is a declaration of extraordinary value. 'You are 11 stone to me' is a factual observation about mass that will not appear on any greeting card, regardless of its mathematical equivalence.
