Natural Diamond Parcels

What Is a Diamond Parcel?

A parcel is a group of diamonds traded together, usually within a defined size range and quality spread. Parcels are the practical way to supply production: eternity bands, tennis bracelets, line bracelets and repeated designs all require many stones that behave consistently when set side by side. Our parcels cover stones from 0.30 carats per stone and above.

Kether Diamonds sources natural diamond parcels for manufacturers and jewelry businesses, starting from a clear production brief.

What to Include in Your Brief

• Shape and size range per stone (from 0.30 ct), in carats or millimetres
• Total quantity of stones or total carat weight
• Color range and clarity range
• Cut and make requirements
• Fluorescence tolerance
• Whether stones must be calibrated to exact millimetre sizes
• Intended use, for example eternity band, tennis bracelet or line bracelet
• Budget, destination and required date

Calibration and Consistency

For production, calibration is usually more important than weight. A tennis bracelet or eternity band needs stones of the same diameter within a tight tolerance so that they sit evenly in the setting. We recommend specifying the millimetre size and the acceptable tolerance rather than only a carat range per stone.

Consistency of color and brilliance across the parcel is equally important. A parcel that mixes several color grades or makes may look uneven once set. State the acceptable spread clearly, and we will source within it.

Parcels and Individual Stones Together

Many projects combine a parcel for the side stones with an individual center stone. Both can be sourced within one request, so the center stone and the accents are selected to complement each other.

GIA Grading Reports

Every diamond sold by Kether Diamonds is accompanied by a GIA grading report. The report records GIA’s grading observations for the submitted stone, including carat weight, color, clarity and, for round brilliants, cut grade, together with measurements, polish, symmetry and fluorescence. Buyers can verify the report details through GIA’s official Report Check service before approving a purchase.

Who We Work With

Kether Diamonds works with jewelry retailers, independent jewelers, manufacturers, designers and professional diamond buyers. Our team operates from the Ramat Gan Diamond Exchange, with representation in Antwerp, Dubai and New York, and coordinates each request through one point of contact from the initial brief to delivery.
