\n\t\t\t\tThe Swiss Gemmological Institute (SSEF) has issued a warning advising the broader industry that emeralds sent for lab testing may be re-treated before being sold again. \n\t\t\t<\/p>\n

SSEF stated that filling emerald cracks with oil, wax, or artificial resin is common practice. However, the Laboratory Manual Harmonisation Committee (LMHC) guidelines require full disclosure because this treatment affects value.<\/p>\n

Laboratories assess a gemstone\u2019s condition only at the time of examination. Consequently, reports may misrepresent re-treated gemstones as having no or minor clarity modifications.<\/p>\n

Buyers in the luxury market prefer emeralds with little to no clarity enhancement, leading to increased scrutiny of treatment disclosure and reporting accuracy. SSEF added that its reports reflect the gemstone’s condition only at the time of testing and do not guarantee its state thereafter. If a fissure is detected, the report specifies its type, extent, and the presence of material.<\/p>\n

The industry is advised to verify the authenticity of reports, re-examine colour gemstones prior to purchase, avoid relying on outdated reports, and handle heavily fissured or treated emeralds with care due to their fragility.<\/p>\n
