Beautiful vintage set. Minimum of 1/2 carat or 5mm center stone and 9 additional 2mm each stones for a minimum tw of .77 carats or just over 3/4 tw. These are natural, white, eye-clean stones. Probably in the I range of clarity. Color possibly G - J in color. I’m not a gemologist. Total weight can only be confirmed by removing from the setting. Clarity and color could be off a little but I don’t think by much, if at all. All in all, a very nice older set with plenty of life left in her. The bigger stone size is 6.5 and the guard ring is 6.25. Both are sizeable. Usually can go up or down two sizes is a general rule of thumb. A jeweler could tell you better.

Item is marked 14k but could be off in either direction. This is normal for older items and anything not marked as plumb gold.

The actual purity will be checked by the authentication process.
