Yes, we can engine turn Platinum but if you want it to look half decent then don't bother with the soft GW alloy used for mounting. Use the HM (Hard Machining) alloy instead if you can get it. As a last resort one of our customers once used the P Pinwire alloy for a Platinum Ruler we did which was bevelled and fluted like the gold one shown here. This was not ideal but worked OK.

One of the rarest of precious metals, platinum also is one of the strongest and heaviest, making it a popular choice for setting gemstone jewelry and watches. It has a rich, white luster, and an understated look. Platinum is hypoallergenic and tarnish resistant. Platinum used in jewelry and watches is at least 85 to 95 percent pure. Many platinum watches are produced in limited editions due to the expense and rarity of the metal.
