This image is from a very old bracelet, hearts painted apparently as ceramic, pretty much cracked now. I have had the bracelet for about 70 years. It was given to me by an aunt who was attending UCLA, and there was a member of the Hawaiian family? as the story was told to me, that was maybe a princess. The name given to me I cannot exactly remember, but something like Leihani. I have looked at some data online and the time frame does not seem to fit, but i have no doubt that my aunt had some information about the origin of the bracelet, as it was linked to a Hawaiian royal family.
Here is one such “heart” from 8 hearts. This looked Chinese to me, but a friend said that maybe it was closer to Japanese and NOT cloisonne, perhaps a painting.
Two images below are the original image (bottom) and top, vectorized, just for a different look. I would welcome any comments, though i have comments turned off on this wordpress site, i think you will find my email somewhere else, like PDQpatterns(dot)com.
The actual heart is a little less than 3/4 of an inch from point to top
