Saffron is sold in small quantities because harvesting the usable filaments requires substantial hand work.

The International Organization for Standardization explains that each saffron flower has three stigmas, which are picked by hand, and that producing one kilogram of filaments can require more than 75,000 flowers (ISO source). This labor is one reason saffron costs more by weight than many other spices.

What affects saffron price?

  • Quantity and packaging: compare the net price per gram, not only the package price.
  • Form: threads allow visual inspection before grinding; powder saves the grinding step.
  • Origin and traceability: look for a stated origin, lot identifier and seller contact information.
  • Documented testing: a formal grade or ISO-conformance statement needs current evidence tied to the product or batch.
  • Storage and condition: damaged packaging, moisture or poor storage can reduce value.

How to compare an offer

Check the net weight, shipping charge and return terms, then compare like with like. The current ISO 3632-1 specification covers filaments, cut filaments and powder; ISO 3632-2 provides laboratory test methods. Color, aroma or an all-red appearance can help with a basic inspection, but none alone proves purity or grade.
