This is lab created yellow-orange lithium tantalate facet rough. Each is labelled with its gram weight and letter in the photo and they can be purchased individually.

This is erbium-doped lithium niobate, a rare laser crystal which has been used in new breakthrough on-chip lasers.  The erbium allows it to act as a far infrared laser crystal but also gives it a gorgeous pink-to-orange color changing base color as well as strong green fluorescence.  Cut stones may have a green cast in direct lighting, and should otherwise resemble a pink diamond(!)

This is lithium niobate (LiNbO3), an unusual crystal with very interesting properties.  Colorless lithium niobate was once popular as a diamond simulant but it really isn't that good of one simply because it's much brighter and more dispersive than a diamond, with an RI of 2.3 and a dispersion of 0.13 (vs 0.044 for diamond--dispersion measures its ability to split white light into a rainbow).  That means cut stones give of brilliant rainbows of color, and it makes for an amazing gem in its own right for those reasons.

Note its hardness is around 5 so it is not a good stone for rings but is fine for lower-wear jewelry like pendants.
