Parcel Paper — The Folded Square at the Heart of Trade Practice
How loose stones travel, sort, and present in the gem trade
The parcel paper is the small folded paper envelope used to hold and present loose gemstones in the trade. It is one of the most ubiquitous and durable items of bench and dealer-table equipment, and the basic design — a glossy paper square folded into a triangular pocket — has been essentially unchanged for at least a century. The Dutch and Afrikaans gem-trade term briefke (literally little letter) is also used. Parcel papers protect stones from scratching, allow safe handling without direct contact, and provide a neutral background against which colour can be evaluated under buyer's lighting.
Construction
A standard parcel paper is a square of glossy or coated paper, typically white but available in coloured stocks for specific evaluation purposes. Sizes range from approximately 25 millimetres for melee through 50 millimetres for medium stones to 75 millimetres or larger for principal stones. The square is folded along three creases — first into a rectangle, then twice into a smaller rectangle, then folded over and tucked to form a closed triangular pocket. The folded paper holds stones securely and can be opened, displayed, and refolded repeatedly without losing integrity.
The interior surface of a parcel paper is typically white because white is the standard neutral background for colour evaluation in coloured stones and diamonds alike. Coloured papers — pale blue, dove grey, black — are used in specialist evaluations: blue paper for evaluating yellow diamond, black paper for fluorescent stones, grey paper for translucent or milky materials.
Use in trade practice
Parcel papers travel through every level of the gem trade. Mining and cutting centres pack rough into parcel papers for transit and grading. Wholesalers store cut stones in parcel papers labelled with weight, origin, lot number, and price. Dealers present parcels to buyers by laying out the open papers on a sorting tray under controlled light. Bench jewellers use parcel papers to hold loose stones during setting, mounting, and design work. Auction houses present catalogue-lot stones in parcel papers in viewing sessions.
The label on the outside of a parcel paper is the standard locus for trade information: weight in carats, dimensions, colour and clarity grade, lot or stock number, and any laboratory report reference. Disciplined labelling makes parcels traceable through transactions and is a basic professional skill in the trade.
In the trade
For Skyjems, parcel papers are standard equipment at every desk and bench. We keep stocks in white and pale-grey papers in three sizes and use them for inventory, transit, and presentation. The discipline of folding and labelling is taught to every new staff member as a basic professional standard.
