Book Description
From the dawn of time, ruby and sapphire have both attracted and fascinated humans in ways that few other items could.While objects of desire are found throughout the natural world, physical beauty is too often ephemeral. From the allure of a man, woman, flower or butterfly, through the fleeting moments of a sunset, there is little that lasts and practically nothing that can be passed down to our descendants. The exception is precious stones. Not only are they the most durable creations of mother nature, but their visual splendor is truly eternal.In this companion to his 2013 book, Ruby & Sapphire--A Collector's Guide, Richard Hughes examines these gems from the gemological standpoint, delving into these gems not just from the aesthetic, but also from the scientific point of view.The product of nearly 40 years of firsthand experience, it covers every aspect of the subject from A-Z. History, sources, prices, quality analysis, synthetics and treatments, everything is here. Ruby & Sapphire--A Gemologist's Guide represents the most comprehensive book ever written on a single precious stone. With over 1000 photos, maps and illustrations and 3500 references, it is nothing less than a tour-de-force of gemological scholarship.

Book Description
The Ruby Red Trilogy: Ruby Red, Sapphire Blue, and Emerald Green This internationally bestselling series follows Gwyneth Shepherd, a girl with a time-traveling secret. Traipsing through past centuries, juggling a potential romance, and unlocking her destiny, Gwen has her work cut out for her. Ruby Red: Gwen has always known that her family is different—the women, in particular. As time travelers, they are no strangers to the possibility of the impossible. But even they are't expecting it when Gwen shows signs of being a time traveler rather than her cousin Charlotte. Thrust into a world she should have been excluded from, Gwen is introduced to Gideon, a fellow traveler. Although the two don't get along, something other than annoyance might be brewing under the surface. As Gwen masters her new ability, she learns more abou therself than she ever could have imagined. Sapphire Blue: Gwen has joined the ranks of the Circle of Twelve, a secret society of chosen time travelers. As the Ruby, Gwen is tasked with finding travelers in the past, all while delving into prophecies and trying to read the mixed signals that Gideon, the Diamond of the Circle, has been sending. With the help of her best friend, a ghost, and a gargoyle demon, Gwen seeks to unearth the truth behind the Circle—a truth that has been actively hidden from her. Emerald Green: Crushed to learn that Gideon may have been deceiving her all along, Gwen has to move forward nonetheless. She has more than enough on her plate: her distrust of Count Saint-Germain, founder of the Circle of Twelve, who wants Gwen to finish collecting blood from the other chosen travelers; the chronograph, a device which will close the Circle if she succeeds; and the resistance she meets at every turn as she seeks more knowledge. With much more to be revealed, Gwen must race against the clock to fulfill her destiny—before it's too late. Includes bonus chapters from Kerstin Gier Dream a Little Dream!
