C&S-Ruby-Genuine

Blood-red. Fire-red. Color that burns along the veins, and gives brightness to the night. If you’re looking for the color of life itself, look no further than red. And the gemstone that brings red to vivid life can have only one name: Ruby. The “king of gems,” Ruby is one of the world’s oldest and most revered gemstones. It is also one of the rarest. The mineral Chromium is responsible for the gem’s startling color. Rubies with hardly any inclusions are so rare that large stones of good color fetch higher prices at auction than even diamonds. Fiery and romantic, showing brilliant depth and intensity, the red hue of Ruby is certain to draw attention. In settings that focus attention on voluptuous color, Ruby sends a message of drop-dead glamour and femininity. Geometric-inspired jewelry designs featuring Ruby are equally appealing to both men and women who seek to convey strength, honor and classic style. Ruby is the gem most often bestowed on those born in July as well as those born under the sign of Aries. Its arresting hue speaks of passion and love, making it a stunning gem option for the celebration of the 15th and 40th wedding anniversary. Our Ruby selection includes commercial quality – ideal for repairs along with a consistent supply calibrated Ruby. Larger sizes are available as part of the Black Box Gemstone® collection. While Ruby producing countries include Thailand, Cambodia, Sri Lanka, Kenya, Afghanistan, India, Pakistan, Tanzania and Madagascar, almost 90% of the world’s production of Ruby is from Myanmar. Due to human rights abuses in this country, the United States government has banned imports from Myanmar, making our on-hand supply of Ruby limited. We do, however, currently offer a small assortment of untreated Ruby from Madagascar. Thailand was once a major contributor of Ruby to the world, producing the famous “Siam” Ruby. We are currently partnering with mines in that country to revitalize the vivid Siam gem.
