Fancy Red Color & Radiant Format

 

The Fancy Red grade provides a defined color specification for sourcing, while the cut-cornered rectangular modified brilliant format offers a clear dimensional reference for jewelry development.

For production or collection sourcing, additional stones can be specified by Fancy Red grade, agreed visual color range, carat weight or range, clarity, shape, dimensions, and matching tolerance. This is particularly relevant when multiple stones need to maintain a consistent appearance within the same jewelry collection or production run.

The 7.26 × 5.42 × 4.01 mm measurements can also be used as a reference for CAD development, setting design, stone-fit checks, and production planning.

 

 

IGI Certification & Treatment Disclosure

The 1.56 ct Fancy Red VS1 CVD Radiant is available for purchase as an Individual Stone, subject to current inventory.

For larger requirements, sourcing can be evaluated according to carat or size range, Fancy Red color grade, visual color range, clarity, shape, dimensions, quantity, and matching requirements. Bulk and OEM supply are available subject to product specifications, inventory, and production scheduling.

 

 

Matching & Repeat Sourcing

 

For multiple-stone requirements, sourcing specifications can be established around:

  • Fancy Red color grade
  • Agreed visual color range
  • Carat weight or range
  • Clarity range
  • Cut-cornered rectangular modified brilliant shape
  • Millimeter dimensions
  • Quantity
  • Matching tolerance

For Fancy Red diamonds, defining both the grading range and an agreed visual color range provides a more practical reference when sourcing stones for the same collection or production requirement.

The same specifications can be used as a reference for subsequent sourcing, subject to inventory and production availability.

 

 

Production & Quality Control

 

Production and processing include CVD growth, diamond processing, dimensional measurement, and visual inspection.

For individual and bulk orders, these stages support control of:

  • Color and visual appearance
  • Stone dimensions
  • Shape and cutting specifications
  • Visual quality
  • Matching requirements for multiple stones

For certified stones, the IGI report provides the external grading and individual identification reference for the specific diamond.
