A large titanium steel nameplate will be stamped anyway you want. Everything about this piece is sized up for a man. Nothing dainty or petite! This is much better than scratching or destroying them yourself with regular jewellery cleaners. Even the jewellery cloths may be too much for some stones. Make sure though that they are not cleaned too often as this can be very counterproductive and actually weaken the stones.
