September Birthstone: Sapphire

September Birthstone: Sapphire | Vardy's Jewelers Bay Area

September’s birthstone is the Sapphire. Did you know sapphire is the name given to the corundum mineral species when it appears (primarily) in shades of blue? Red corundum is classified as ruby. Any non-red shade–including pink and colorless–is considered sapphire. There are other categories known as “fancy sapphires” (violet, green, yellow, orange, pink and purple) and “parti-colored sapphires” (combinations of these colors). Some sapphires change color depending upon their viewing conditions, appearing blue in daylight or fluorescent light and purple under incandescent light. Sapphires even appear in gray, black, or brown hues. Titanium and iron are the trace elements that cause sapphire’s blue, which ranges from pure blue to greenish-blue or violetish-blue. The strength of sapphire’s blue depends on how much titanium is present-—the more titanium, the deeper the blue color.


  • The name sapphire comes from the Greek word sappheiros, which probably originally referred to lapis lazuli.
  • A stunning 18-carat oval blue sapphire surrounded by diamonds graces the world’s most famous engagement ring (given by Britain’s Prince Charles to Lady Diana Spencer in 1981). The most recent recipient of the ring is the former Kate Middleton, Princess Diana’s daughter-in-law.
  • Deep blue sapphires have long been associated with royalty which may have contributed to the coining of the color known as “royal blue”.
  • Sapphires are traditionally given on 5th and 45th wedding anniversaries.
  • A rare orangy-pink sapphire color is called padparadscha, which means “lotus flower”
  • Sapphires are among the most durable naturally occurring elements in the world. The Apple Watch features lab-created sapphire glass in its screen!
  • Traditionally, sapphires are believed to symbolize nobility, truth, sincerity, and faithfulness.

Sapphires come in a variety of hues. Color is the strongest factor when determining the value of a blue sapphire. The most highly prized blue sapphires are velvety blue to violetish blue, in medium to medium dark tones. Preferred sapphires will have strong to vivid color saturation regardless of hue. The major fancy sapphire color categories are padparadscha, pink and purple, orange and yellow, green, and colorless and black. The desirability of other sapphire colors is more or less as follows:

  • Preferred padparadscha sapphire colors are intensely saturated and range from light to medium pinkish orange to orange-pink.
  • The finest orange sapphires are strong, pure orange to red-orange with medium tone and vivid saturation.
  • The finest yellow sapphires are yellow to orangy yellow with vivid saturation.
  • With color-changing sapphires, the strength of the color change is the most important quality factor affecting its value, followed in importance by the actual colors of the stone.
