Trio of small but radiant pendants + a chain

Three lovely creations, the longest, the cross, about an inch long. I believe it's one variation of the Agadez cross, the most popular category of Saharan Berber jewelry made especially by the Tuareg people of Niger. It's marked BO on the bail. I think the sparkly one is made of goldstone glass, which is often mistaken for stone. The faceted topaz (also likely glass) plays nicely with the light. I've included a lightweight chain, marked Germany, which pairs especially well with that pendant. All are in great condition.There is a streak of solid colour in the goldstone, visible in the second picture, and it would benefit from a bail. (d)
