Goldstone

N/A (Synthetic Glass with Copper Inclusions)

Red gemstone ring, likely synthetic ruby or red spinel

Ruby: corundum (Al₂O₃); spinel: MgAl₂O₄; exact identity requires testing

Blue glassy mineral fragment, possibly sodalite or dyed/cobalt glass

Opalite

Synthetic Opalized Glass (SiO2 + additives)

Blue opalite (often sold as synthetic opal)

Opalite glass; amorphous hydrated silica if natural opal (SiO₂·nH₂O)

Dyed or synthetic turquoise-blue glass-like specimen

Likely man-made colored glass or resin; exact identification requires testing

Pink-red faceted gemstone, possibly synthetic corundum or spinel

Uncertain; possible ruby (corundum, Al₂O₃) or red spinel (MgAl₂O₄)

Opalite

Opalescent Glass (SiO2 + coloring agents)
