Ruby Necklaces and Pendants
Some rubies produce a six-ray star that covers their entire surface when the stones are cut and polished to create cabochons (smooth domes, rather than faceted gems). Star rubies are one variation of the gem that are found in North Carolina ruby mines.
Ruby is the July birthstone, but is popular with people born throughout the year. The gem is has been associated with love since ancient times.
Rubies found most commonly in jewelry have been heat treated to improve their color and clarity, and dyes are sometimes used to deepen their color. You'll encounter rubies that have been coated to hide fractures on their surfaces, but be aware that the coatings do wear off.
High quality natural rubies are rare, especially when they are large. Expect to pay a premium price for these stones, and always ask for an authenticity report from a reputable gem lab before making a purchase.
Most of the rubies found in jewelry are heat-treated to improve their appearance, and some of the gems may be synthetic (grown in a laboratory). Read descriptions carefully and ask the retailer as many questions as it takes to understand your potential purchase.
Ruby is a durable gemstone, and is rated at 9 on the Mohs' scale -- diamond is the most durable, and is rated at 10.
