So here is another jewel.
The Twist is the first of the Jewels of the Lake, a set of enchanted jewels that Aeghiss made for Chrysis.
Though the shape looks simple, it was actually a bit tricky to do, and I had to use the
curve modifier to shape the twist as a ring (which implied making a twist with a whole number of turns and... a 12/π -radius circle.)
The Twist is made of a strand of silver and one of blue steel twisted together, and there should be small diamonds incrusted in the twist but oh well... This was complicated already so... Maybe another day.
