In anticipation, I tracked my ring via FedEx website! It arrived today! Awesome! I love the weight of my 15g THOR. Comfort Fit very comfy! The free ring sizer was a great help! More importantly was your advice to order a half size smaller for Comfort Fit! I'll wear it 24/7 Forever! I'll highly recommend Tungsten World to all! THANK YOU for such quality & speedy service. The wood box & gift bag are a nice touch too!

Vacuum Metalizing - VM Grade Tungsten Strand
VM grade tungsten wire, used in VM strand, is made by controlled processing techniques starting from the ore and continuing through doping and wiredrawing. Highly purified tungsten oxide, which has been reduced to tungsten powder in pure hydrogen, is pressed into bars, sintered, and worked into wire. The wire, drawn to size, is cleaned and stranded in various combinations as desired. As a result, our high-purity doped strand is produced to provide a uniform and controlled recrystallization rate important in the vacuum-metalizing process. The techniques allow achievement of a high number of flashes per coil by eliminating premature coil brittleness, distortion, and sag, the major causes of failure during reloading and processing.
