The materials in a display case determine three things: how the jewelry looks, how long the case lasts, and how much it costs. Understanding the options helps you specify with confidence instead of relying on a supplier's default.
Low-iron glass: the window to your product
Standard float glass contains iron, which gives it a subtle green edge. In a jewelry case — where customers examine stones up close — that tint distorts color. Low-iron (extra-white) glass removes the iron, achieving 91% light transmission and true color rendering. An optional anti-reflective coating further reduces glare under spotlights. For high-value retail, low-iron glass is the baseline, not an upgrade.
Stainless steel: the durable frame
304 stainless steel is the workhorse of commercial display fixtures. It resists fingerprints, corrosion, and wear, and accepts brushed, mirror, or powder-coated finishes. For coastal or high-humidity locations, 316 marine-grade stainless offers additional corrosion resistance. Steel frames are more expensive than wood but deliver a 15-to-20-year service life with minimal maintenance.
MDF: the versatile substrate
Medium-density fiberboard (MDF) is an engineered wood product made from fine wood fibers bonded with resin. It is dense, stable, and takes paint and veneer beautifully — which is why it is the most common substrate for lacquered and wood-veneer case bodies. MDF is cost-effective, dimensionally consistent, and can be machined into complex profiles. It should always be sealed or laminated on all surfaces to resist moisture.
How to choose
- High-traffic flagship — stainless steel frame, low-iron glass, stone or solid-surface tops
- Boutique or concept store — lacquered MDF body, brass or steel accents, low-iron glass
- Pop-up or temporary — lightweight MDF panels, reusable graphics, standard glass
