Re: Super-Durable simple rings (wedding rings)

There is a category of metal I would direct you to, and recommend highly. It is known in the dental business as "base" metal. It has a rough formulation of Nickel 76%, chromium 14%, Molybdenum 6%, and beryllium 1.8% (don't breath the beryllium dust when grinding). This metal is castable, therefore any waxed design (as in gold casting) can be successfully cast. It is VERY hard and durable, but once "polished" will maintain any patina that one ends with very well. I say "polished" for it is difficult to obtain the high polish of gold or silver/palladium mixture. If you two geologist bang those rings on particulate safire (sp?) all bets are off. Personally I like the different lusters and areas in a ring... it certainly does not look manufactured. Also the color is different from sterling... a grayer look. I've used it for rings mainly for the color, and lightness (ear rings). Also, I've done a second waxing and casting (over selected areas of the first casting) to incorporate gold next to the gray-silver color... nice! I'm told this metal formulation is close to various inconels I purchase mine from Jeneric/Pentron Inc.(1800-243-3969 Note: they are a dental supplier and may not sell to anyone) Their "NP Round" is the same as their "Rexilium lll" and slightly cheaper (they sell in 5 oz. lots, bunches of small round cylinders). Many companies have competing metals. There are various formulation to tolerate different coefficients of expansion of dental porcelains (feldspar based... not glass) which are fired to, and fuse to this metal (the process is complicated and requires special vacuum ovens). Therein is another jewelry option... fusing dental porcelain to the ring for more color variations. The metal melts at over 2000 deg F. therefore a quarts crucible is needed and special investment, and an oxygen-fuel gas torch (propane-O2 is best) Talk to dental labs or dentists who do their own porcelain lab work (like me). wil (Austin,Tx)
