With a relatively high refractive index that induces sparkle and a Mohs hardness rating of 8, topaz, November’s birthstone, is a favorite of both jewelry designers and jewelry lovers. Those looking for color, clarity, and value in a colored gemstone need look no further than topaz. This gemstone displays a remarkable diversity of color, ranging from yellow, orange, pink, and red to brown, green, blue, and violet. Deep golden yellow topaz (sherry topaz) and pink topaz rank among the most valuable colors.

Also quite popular is blue topaz, which is almost indistinguishable from aquamarine when seen with the naked eye. Topaz fanciers are often drawn to “imperial” topaz, a high-quality, intense brownish orange stone that is in a category by itself. This month’s birthstone is equally lovely gracing a ring, necklace, bracelet, brooch, or earrings. Topaz is durable and lends itself well to both formal and informal pieces.
