BTW :: Rutilated Quartz

Did you know that quartz is the single most abundant mineral on earth? Or that it makes up 12% of the earth's crust? I didn't until I went looking for the causes of Rutilated Quartz, which is the stone in these earrings. 

Rutile are inclusions that form in long thin needles "frozen' inside stone such as quartz, but also known to cause the 'star' in sapphires and rubies. Huh, who knew? It is formed when rocks start to cool after being heated by high temperatures and pressure. The pressure eases and the stone separates creating rutile crystals trapped inside the quartz. 

These rutile quartz earrings have a black inclusion, but I've seen others with deep green. Both black and green are tourmaline deposits within the crystal. I just love the patterns they make in the stones. That's what's on the bead table this week.

I love rutilated quartz! Golden rutiles especially have such a rich, luxe quality about them. Those earrings are so perfectly elegant and refined :)

How interesting, Cynthia! I've never seen rutilated quartz upclose before. I love the tear drop shape of the quartz!

I didn't know that about quartz. I bet my daughter will get a kick out of that when I tell her.

I love rutilated quartz -- then again I love the idea of something being made even more beautiful as a result of heat and pressure. Maybe I'll start referring to my grey hairs and crow's feet as my own personal rutiles...

Beautiful pieces! I have worked with a variety of quartz over the years but never rutilated. It has a cool edgy look!
