Starting later in 2025, GIA<\/span> <\/span>will abandon the full 4Cs<\/a> (<\/span>c<\/span>ut, <\/span>c<\/span>olor<\/span>, <\/span>c<\/span>larity<\/span> and carat weight<\/span>) for lab-grown diamonds, switching instead to two simplified categories: \u201cPremium\u201d and \u201cStandard\u201d or no grade at all if a diamond <\/span>doesn\u2019t<\/span> meet the minimal quality benchmark.<\/span><\/span>\u00a0<\/span><\/p>\n

GIA reports<\/a> that over 95% of lab-grown diamonds are already colorless (D\u2013F) or clarity VS1 and above, resulting in a concentrated range of high-quality grades, which makes traditional distinctions less meaningful.<\/span><\/span>\u00a0<\/span><\/span><\/span><\/span><\/p>\n[\/et_pb_text][\/et_pb_column][\/et_pb_row][et_pb_row _builder_version=”4.24.0″ _module_preset=”default” global_colors_info=”{}” custom_margin=”-9px|auto||auto||”][et_pb_column type=”4_4″ _builder_version=”4.24.0″ _module_preset=”default” global_colors_info=”{}”][et_pb_text _builder_version=”4.24.0″ _module_preset=”default” text_font_size=”16px” hover_enabled=”0″ global_colors_info=”{}” sticky_enabled=”0″]

This shift is intended to help consumers better differentiate between <\/span>lab-grown versus natural diamonds<\/span><\/a>, rather than directly comparing lab categories to natural 4C gradations.<\/span><\/span>\u00a0<\/span><\/p>\n
