The Helix aquamarine

Originally brought out of Brazil in the 1930’s, and long in the collection of a famous gem cutting family from Idar Oberstein in Germany, it was left uncleaned for nearly 80 years before being recently prepared and sold. The stone hasn’t been heated either, to produce the slightly bland blue almost ubiquitous in commercial aqua today, but left in its original state, with the beautiful green-blue hue that originated the name aquamarine. The inclusions within that give it its name are phantom crystal surfaces, where growth stopped, and then resumed in the slowly crystallising pegmatitic mush in which it was born. The crystal weighs over 7kg, measures 24.5×12.6×9.3 cm and is currently on loan to the Perot Museum of Nature and Science in Dallas. It is considered one of the planet’s great gems.

sterekweek-2018:

Day seven of Sterek Week, Halloween, is now starting!!

Wendsday October 31st- Halloween: Our last day this year is my personal favorite day of every year: Halloween!! From ghoulies and ghosties and long-legged beasties, let your love for Sterek rule the night! The best part of Halloween themes is that you can use the actual holiday as Halloween for your theme- picking out costumes, trick or treating, and carving pumpkins, or you can just use what Halloween REPRESENTS- the celebration of all things magic, haunted, and living in the shadows, or hey, you can always combine it! You could also mix Halloween mythologies and modern day Halloween, maybe something special happens to werewolves on Halloween, maybe the Hales have always had a history of Halloween parties and some wicked pixies take over, maybe Stiles goes to the woods as Little Red Riding Hood and his Big Bad Wolf is waiting there for him… this may be the end of Sterek Week this year, but mark my words, as long as there is Halloween, there will be Sterek Week!
