This Custom Diamond Sign is manufactured to order rather than picked from a catalogue: the size, finish, lighting and fixing method are all set to your site. Mounting options include freestanding, hanging, wall mount, and the fixing hardware is specified for the surface you have. Returns are formed from stainless steel, galvanized sheet, acrylic, and the face material is chosen to suit the lighting. Send the dimensions and a photo of the site and we will confirm the build on a drawing before production — MOQ is one piece and standard lead time is 7–15 working days after approval.

Diamond Sign Production Specification

Our custom diamond sign combines sparkling diamond-cut acrylic faces, bright LED lighting, and durable metal returns. Available in custom sizes, colors, and finishes, these eye-catching diamond LED letters create a brilliant crystal-like effect for retail stores, malls, salons, events, and luxury commercial spaces.

1. Raw Materials

Each diamond letter is manufactured using carefully selected materials:

  • 3–5 mm acrylic face panel with a diamond-cut effect
  • High-brightness LED strips or modules
  • Galvanized steel, stainless steel, or aluminum letter returns
  • Waterproof electrical components available for outdoor projects

02. Manufacturing and Size Standards

Minimum Stroke Width

≥ 2 cm Sufficient stroke width is required to accommodate the diamond-effect acrylic face, internal LEDs, and metal letter structure while maintaining uniform illumination.

Recommended Minimum Character Size

  • Standard English letters: ≥ 7 cm
  • Artistic or decorative English fonts: ≥ 20 cm
  • Complex logos and narrow fonts: subject to technical review

Recommended Return Depth

The return depth should be selected according to the character height and stroke width:

  • Characters measuring 20–40 cm: 5 cm return depth
  • Characters measuring 40–60 cm: 6 cm return depth
  • Characters measuring 60–70 cm: 6–8 cm return depth
  • Characters larger than 70 cm: 8–10 cm return depth

These production standards help the diamond LED letters maintain consistent brightness, clear contours, and an attractive three-dimensional appearance.

03. Metal Return and Color Options

The stainless steel returns are typically manufactured from 0.5–0.8 mm thick metal sheets. Brushed and mirror-polished silver are available as standard finish options.

Electroplated Finishes

  • Titanium gold
  • Champagne gold
  • Rose gold
  • Mirror black
  • Other glossy metallic colors

Antique Metal Finishes

  • Antique bronze
  • Antique brass
  • Antique copper

Custom Painted Finishes

Custom spray-painted or powder-coated colors are available according to:

  • Pantone color codes
  • RAL color codes
  • Customer-supplied color samples
  • Approved project color charts

Choose from a wide range of diamond colors and customize the LED color, letter size, metal finish, and surface treatment to create a unique diamond sign that perfectly matches your brand.

4. Product Advantages

5. Limitations of Diamond LED Letters

Higher Production Cost

The faceted acrylic, metal fabrication, and LED installation make a diamond sign more expensive than standard front-lit letters.

Additional Weight

Large letters require deeper metal returns and stronger mounting systems, which can increase the total weight and installation complexity.
