What is meant by the term "parcel" in the gemstone trade?

The term "parcel" in the gemstone trade refers specifically to a quantity of stones offered for sale together. This term is often used in the context of wholesale transactions, where dealers may buy or sell a selection of gemstones that are bundled together. Parcels may contain stones of similar types, sizes, colors, or characteristics, allowing for efficient trading and pricing. This practice is common because it simplifies the buying process for retailers and enables them to acquire various stones at once rather than individually sourcing each one.

Understanding this concept is key for anyone involved in the gemstone industry, as it affects negotiations, pricing strategies, and inventory management. The other options describe various aspects of gemstones but do not align with the specific meaning of "parcel" in trade terminology.
