Ultimate Guide to Colored Gemstones

One of the greatest advantages of working together with Jewelry by Johan is the ability to personalize most of the engagement rings, wedding bands and other unique accessories with different elements that best fit your style and personality, including gemstones! Customizing a design with a different gemstone, or supplying your own gemstone, is very common and simple. This ultimate guide to gemstones by color is designed to help you find your perfect gemstone to create your dream ring or other accessory.

One last thing to know before you go treasure hunting for your perfect stone. The ability to swap gemstones is usually based on the setting type and Mohs scale rank for stone hardness. Here are the general rules:

  • Prong Setting - Hardness of 5.5 or higher
  • Bezel Setting - Hardness of 6.5 or higher
  • Flush Setting - Hardness of 7 or higher
  • Tension Setting* - Hardness of 8.5 or higher

*For softer stones, in many cases a faux tension setting can be used; it appears the same, but has a supportive piece of metal to secure the stone vs. using only the tension of the metal.

YOUR GUIDE TO GEMSTONES BY COLOR

Below you’ll find information on gemstones, grouped by common colors, and we’ve included a general comparison on cost ($ = low to $$$$$ = high) and each stone’s Mohs rank for you to make it even easier to find the best stone for your style and budget!

WHAT GEMSTONES ARE RED?

Red, the color of love, is most commonly represented in citrine (November birthstone), garnet (January birthstone), ruby (July birthstone) and topaz (November birthstone).

WHAT GEMSTONES HAVE MULTIPLE COLORS?

Alexandrite, mentioned previously, has a unique stone phenomena that makes it appear to have multiple colors. In daylight, Alexandrite appears more greenish-blue; at night, it has a more prominent purple-reddish hue. It’s like a two-for-one! Opals and salt and pepper diamonds also boast more than one color. Moonstones are slightly opaque with an adularescence of pink and/or blue.
