Howdy From Texas...We are excited to have found this site...As liquidators of estates we run into some interesting gems and pearls regularly...This one has us stumped...It is a baroque looking pearl/stone, the color of a beautiful South Sea Black Pearl; however, it is flat cut on the backside (ala cabachon) and the coloration is akin to a dull slate...The frontside is very pearI like, I have attached photos for your perusal and hope someone can enlighten us...The light color on the pearl/stone is a shadow...Thanks for any input...Eric and Debbie
