Oscar de la Renta Scarab Necklace Egyptian Semi Precious Vintage

Hi there! This interesting piece was my mom's, she was a fashionista and had incredible taste. She was a singer/pianist and would pack the Hilton in Manhattan in the 60's. Anyway, this piece I adore looking at and have had it hung on display in my home but I have never felt cool or fab enough to wear it. I have so many keepsakes it's ok to let some things have a new life and home! Anyway, the photos I've attached are thus: the first one, (of it resting on a black jeweler's display), I found off the internet. The last few pics are also of screenshots from a couple other places as well. I notice that between all four version of the necklace (mine and the other three pictured), each one is unique; with variation in which types of semi-precious stones were used. I personally don't know enough about which stones are which, but in my necklace, the tiger's eye and turquoise are obvious. I took a pic of the bigger beetle in front of my window so you can see its translucent pink color.
