Designed in a torque style in Bold solid forged copper, Latitude is modernist, geometrical, brutalist Industrial with a clean visual feel and made to last like I say sometimes... "archeologists might find it in the future"... 
The focal geometrical form has a raw corundum stone set Into the metal and the whole fabricated element is brazed and fused to the neck piece that ends in a clasp anyway would be very difficult to open.
To put it on open up and down instead of laterally -one tip up and the other down- put on like sideways and then close on the same way and its shape will last. If open just to the sides as is our instinct, it will be hard to recover the round shape. I can make you a video if you need.
The pictues where the piece rests on the bust show its size since it is a real human size mannequin.
It measures around the neck -following the curve with a metric tape- as is 18 1/2 approx.
