Diamond brilliance: 5000K+ cool white maximises scintillation and fire - CRI ≥95 ensures spectral accuracy across all gem types
Gold lustre: 3000K-3500K warm white enhances depth perception of gold and rose gold
Jade fidelity: 4000K neutral with R9 >60 - faithfully reproduces the true colour of jadeite and coloured gemstones
Night colour protection: M/P ratio <0.40 in closing mode prevents blue-light colour shift on gemstones left on display
Counter vs ambient: Counter accent 600-800 lx with ambient at 250-350 lx creates 3:1 contrast ratio - jewellery pops without visual fatigue
