Since the duke is in the process of negotiating for his next wife by speaking with the emissary of a wealthy man whose daughter may soon become the next duchess, the reader can safely assume that the "last duchess was also young and wealthy."  That "My Last Duchess" was beautiful is certainly evident in the fact that the duke proudly displays her.  There is "depth and passion" in her eyes, her "earnest glance" and a flush upon her cheek that runs to the throat, but the paint does not quite capture this:  "Paint/Must never hope toreproduce the faint/Half-flush that dies along her throat (that the duke probably slit).

The duchess had eyes for other men, and smiles, too.  This flirtation is what disturbed the duke who had given his "nine-hundred-years-old name to her." 

Who passed without/Much the smile/  This grew; I gave commands;/Then all smiles stopped together.

Jealous and insulted that one who probably does not have such an honorable and pretigious name should betray him, the duke finishes with this wife:  "There she stands/As if alive."  As the duke descends the stairs with the emissary, he points to a bronze of Neptune taming a seahorse, implying that this new wife must be tame, unlike the former duchess who blushes at the attentions of Fra Pandolf who has painted her.
