~ Helpful Hints ~ Remember- Big Crystals Will Make Large Rainbows! Crystal Prisms Love to Play With Light! Crystals Will Make Beautiful Rainbows in Sunlight! The Bigger the Crystals, the Bigger and More Colorful the Rainbows Are! Mix Sizes and Shapes for an Incredible ~ RAINBOW Show! ~ HINTS ON SIZES: 18mm is almost 3/4" (large earring or Dime size), 28mm is 1 1/8" (pendant size, bigger than a Quarter), and 40mm is 1.5 inches. It doesn't sound like much difference, but remember, they are also thicker, heavier, and wider in addition to being longer. The difference in appearance is quite striking! Any size is perfect for a window display. The 40mm is most dramatic, 28mm is smaller but still a good size. The 18mm is quite small but is good if you like small crystals or have a display with large crystals and need some smaller pieces for contrast and interest. Here's a ruler showing both inches and millimeters (mm) so you can compare! COLORS: Crystals are colorless if listed as "mm" (millimeters). The letters "ab" stand for "Aurora Borealis". This is a light coating of 24K gold that gives the crystal iridescent coloring and gold brilliance. It is designed to give colors to a crystal in low light. It still allows it to make rainbows in sunshine. If you like the pure beauty of crystal, get "Clear". If you like a visual impact in any light, and some extra color, try the crystals in "ab". AB is bright and shimmery but is not invisible. It creates changing colors on the crystal the way oil on a puddle makes Rainbows.
