More than a century after Bram Stoker’s Dracula was published, fascination with vampires continues, as seen in film, television, fiction, fashion, and jewelry.

Stephanie Meyer’s Twilight series has not only dominated the New York Times Best Seller list and the box office, it’s also unleashed a torrent of vampire-themed shows and movies, including Vampire Diaries, True Blood, and coming in 2014, Vampire Academy.

Black never goes out of fashion, and this season it’s taking a prominent place in fashion trends, especially in jewelry.

Black diamonds. Black pearls. Black spinel. The love of black-color gems and jewelry ranges from the most affordable to the most luxurious, and for good reason. It’s incredibly versatile. It’s the color of sophistication and elegance. It’s both edgy and timeless.

Fall brings the turning of leaves, the golden glow of pumpkins, and the warmth of fires in the fireplace. While yellow is often associated with the sunny skies of summer, its warm tone is a natural autumn hue, and this fall’s auctions have a number of spectacular yellow diamonds that are fitting for the season.

The October birthstone, opal, is noted for its individuality, magic, and mystery. Its unique display of flashing rainbow colors is unlike any other gem, and has been compared to volcanoes, galaxies, and fireworks.
