Diamond brilliance: 5000K+ cool white maximises scintillation and fire — CRI 97+ 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
