There are eight lamps in the Cathedral family. The crystal lamps are green, amber, and clear, while the moonstone lamps include white, rose, "flesh", apple green, and jade green. The rose moonstone is a very pretty pink, while the flesh moonstone is quite pale and has an amber or orange cast to it. The jade green moonstone has a bluish tint, while the apple green moonstone will have a yellow tint.
A fault shared with the Colonial and Venetian lamps is the sensitivity of the joint between the bowl (font) and the foot. This joint is very susceptible to temperature changes, stress, and bumps. Care must be taken when handling these Aladdin lamps to avoid cracking them at the joint. It is also not advisable to set them in direct sunlight where they will heat up, or in areas that are too cool such as basements or near air-conditioning ducts.
Another problem with the Cathedral lamps is that the recessed oil fill caps often become frozen with age and refuse to unscrew from the lamp. Too much force applied trying to free the oil fill cap can cause the glue holding the female threads to give and the assembly to separate from the font, or worse, the glass font itself will crack or break. Many of these lamps are found minus the oil cap and threads from this mistake!
The "rose moonstone" Cathedral is on the left, while the "flesh moonstone" Cathedral is on the right. They were actually sold as different color lamps and are not just a color variation of the same lamp. The "flesh" color was listed in a 1934 advertisement that announced the new Cathedral lamps for the 1935 year. I would say that the "flesh" color was not widely received however, since the number of rose lamps found by collectors seems to far outnumber the flesh lamps. The difference in color between the two, however, can be so slight that it is often hard for collectors to differentiate between the two. It is much more apparent when the two lamps are placed side by side like these two than it is when looking at an individual lamp. The flesh lamp often has a yellowish, or pale orange, cast to it and is not considered to be a "pretty" lamp by most collectors, so if you're looking at a rose moonstone Cathedral that just doesn't appeal to you due to the color, it may in fact be a "flesh" moonstone lamp. Many of them are also found with color flecks throughout the glass giving them a slightly speckled appearance.
