Lighting Engineering for Jewellery Showrooms: CRI, Lux Levels & Beam Angles
The optical physics behind high-converting jewellery store interiors: balancing 3000K warm gold tones with 5500K diamond scintillation.
Why Color Rendering Index (CRI) Dictates Retail Sales
Color Rendering Index (CRI) measures light source accuracy against natural sunlight. For jewellery retail, a CRI rating above 95 (and R9 red saturation > 90) is non-negotiable to render the deep warm luster of 22K/24K gold and the pristine fire of natural diamonds.
Quick Answers
What lux level is recommended directly over jewellery display counters?
Display counters should achieve 2,500 to 3,500 lux on the merchandise surface, contrasted against 800 to 1,000 lux ambient floor lighting.
