I am a big fan of the Hector Aguilar for Coro sterling jewelry. Many of his taller’s designs were used, with the Coro Made in Mexico circular stamp instead of the HA mark.
I love this lillies pin. I have not seen in person the same design with an Aguilar mark, but I would find it difficult to believe there are any differences. And the Coro one is available for much less than the Aguilar version. I have also seen these designs gilded (as with the flower I posted about previously).
