Victorian cup and saucer - strong geometric design, buttery yellow interior slip with gilding curious cup and saucer, with no makers mark but the diamond style british mark that I've evaluated and using the info at oldandsold.com, I'm able to date this to 1876, which I find odd given the simple, geometric style of this set. I have another cup/saucer in the exact same style that is a pale blue, and I'll have to check the date but they are very close to this set. The pair are in excellent condition, no chips or cracks whatsover, in a very lovely translucent china. There is a slight bit of rubbing of the gilding on the exterior edge of the handle (not shown), but rim gilding is excellent. Here are some photos:
Here is a good view that I copied of the mark on the bottom
Sorry for the hi-res shots- any thoughts, ideas, are greatly appreciated!
