CRI and Spectral Quality: Why \u226595 Matters<\/h1>\n<p>Color Rendering Index (CRI) measures how accurately a light source reveals colors compared to a reference source.<\/p>\n<p>For jewelry environments:<\/p>\n<ul>\n<li><strong>CRI 90 is minimum acceptable<\/strong><\/li>\n<li><strong>CRI 95+ is recommended for premium retail<\/strong><\/li>\n<\/ul>\n<p>High CRI prevents gemstones from appearing flat or gray.<\/p>\n<p>According to professional retail lighting practice guidelines from the Illuminating Engineering Society (IES), accurate color rendering is critical in merchandise evaluation environments.<\/p>\n<p>Low CRI lighting can distort perceived gemstone saturation, reducing visual appeal.<\/p>\n<p>In field experience, upgrading from CRI 80 to CRI 95 frequently produces noticeable improvement in diamond clarity perception.<\/p>\n<hr \/>\n<h1>4.
