Crystal Katana - Black

Aurora Borealis (AB) rhinestones feature a specialty coating applied to the surface of the crystal. This coating creates a shimmering rainbow effect, reflecting warm golds, soft pinks, and vibrant blues depending on the lighting and angle. AB stones are ideal for adding dimension and light play to any design, but they are different from clear or solid-colored crystals; they are treated to sparkle in multiple tones, not one static hue.

Crystals with surface treatments like AB, neon, luminous, and metallic finishes offer high-impact color and shine. However, these effects are applied as a top layer, not baked into the crystal itself. Excessive friction, rubbing, or chemical exposure (like lotions, alcohol, or cleaners) may cause fading or wear over time. These stones are best used on display pieces, accessories with minimal handling, or protected areas of a design.

Do all rhinestone sizes match exactly in color?

No. Glass rhinestones are made in color batches, often referred to as "lots." These batches can vary slightly in tone, saturation, or brightness, even when labeled under the same color name.

This is similar to how fabric, tile, nail polish, beads, vinyl, and paint can shift slightly between lots. Even with precision manufacturing, factors like heat, pressure, coating time, and raw material availability affect each production run.

In rhinestones, this means that:

• An ss16 Emerald AB might look slightly different from an ss30 Emerald AB, even when made by the same brand.
  
• Lighter colors, opals, and coated finishes are more likely to show visible differences across sizes.
  

What you should do:

If your design depends on precise color matching across multiple stone sizes, we recommend:

• Buying all the sizes you need at once
  
• Ordering from the same supplier and brand (like KiraKira™)
  
• Using our curated color mixes, which are hand-balanced for tone consistency across size ranges
  

This helps ensure a more uniform and professional result, especially for high-visibility projects like signage, portraits, or automotive designs.

Most rhinestones have a foil backing that reflects light through the glass to enhance sparkle. The color of that foil: silver, gold, or rose, does not change the color of the rhinestone itself. Instead, it indicates the manufacturer’s intended quality tier or visual presentation.

Foil color is not the full story. What matters is the glass clarity, cut quality, and foil durability. Our silver-backed KiraKira™ rhinestones are engineered for professional use and deliver top-tier results across all surfaces and applications, without inflated pricing based on foil color alone.
