IIGJ Lab (a project by GJEPC India, sponsored by the Ministry of Commerce & Industry, Govt. of India) has updated its ruby treatment descriptions to harmonise with major gemmological laboratories, ensuring scientific accuracy and transparency.
Rubies are commonly heated using substances like fluxes (e.g. borax), which often is mixed with silica-based materials or high-density glass containing elements like lead (P), bismuth (Bi), barium (Ba), yttrium (Y), zirconium (Zr), etc.
Under the current policy all these components are mentioned separately, which is now updated to reflect more unified and simplified descriptions on the ruby reports issued by the IIGJ Lab.
Shri Kirit Bhansali, Chairman, GJEPC said,
“GJEPC is committed to serve India's Gem & jewellery Industry by providing world class Grading, Identification & Certification services. Jaipur is an important centre for Coloured Gemstones and is growing rapidly as jewellery manufacturing centre. We believe the revised description of treatment in Ruby Reports will become important sales tool for the coloured gemstone industry to gain confidence of the Customers. We continue to invest in building skills and Lab infrastructure to meet the growing needs.”
Indications of heating with residues and silica-based substance in fissures or,
high-density glass (Pb, Ba, Bi, Y, Zr) in fissures where no flash effect is observed
Description:
Var.: Natural Ruby
Spe.: Natural Corundum
Comments: Indications of heating and clarity enhancement with residue in fractures and cavities.
Extent: (TE1-TE5) / (F1-F3) - as applicable
Remarks (if lead is detected): Lead glass was detected.
Presence of High-density glass in fissures / cavities with flash effect, numerous gas bubbles, indistinct single crystal
Description:
Var.: Glass-Filled Ruby

Comments: Indications of clarity enhancement by lead/bismuth/barium glass in fractures and cavities.
No quantification in this case.
High density coloured glass in fissures with flash effect, numerous gas bubbles, colour concentrations
Description:
Var.: Glass-Filled Ruby / Sapphire
Spe.: Natural Corundum
Comments: Indications of clarity enhancement with coloured glass in fractures and cavities.
No quantification in this case.
