Amber color pieces: 2 carved leaves + pendant/ triangle/ bead/ teardrop/pieces

Description

These "amber" color pieces are from my mother's collection of jewelry and I cannot find anything they belong to. Perhaps only good for crafters.  I tried the rubbing tests on these pieces and the Pendant with the metal top is the only one that passed! As far as I could tell all the other pieces are NOT true amber.
Two carved leaves, with tiny perforated holes , held together with 4 inked circles. Each leaf measures approx. 1-3/8 inch long x about 7/8 inch wide - but each leaf is curved so if they were flat would be a little wider. Backs of leaves are smooth. Dark amber color.
Bead is 3/4  inch long, hole through center, diamond pattern, yellow color.
Pendant is round with flat bottom, top is pierced by metal "tong-like" fastener. Appears to be permanent. Dark amber color.
Measures 2 inches x 1/4 inch aside from fastener. This piece passed the rubbing test.
Triangular piece is more the yellow amber color. Measures 1-5/8 inch on each side and approx. 1/8 inch thick.
Teardrop-shaped piece may have been part of a piece of jewelry - has a rough spot on back across top. Very pretty, very thin, measures approx. 1-1/4 x 1 inch. Darker color. I think this may just be plastic.
Finally there is a darker color piece with swirled marking, broken off on both ends, about 1-3/4 inch x 3/8 wide.
All pieces are translucent, except leaves.
Appreciate the comments and info!
