Thanks for the pics, princessplease! I can tell you which of my pieces are which:
1) Pendant: checkerboard cut citrine from Brazil
2) Next: round pink tourmaline in rose gold setting from Overstock
3) Next: princess-cut blue topaz in 2-tone setting from Pittsburgh chain jeweler
4) Dark looking one in bypass setting: simulant alexandrite from Helzberg - along with matching necklace, the first piece of jewelry the husband ever got me. He used this ring as a placeholder engagement ring until the real thing came in.
5) Big halo ring: Brazilian ametrine in LOGR-esque setting from Ebay. In real life, the window does not appear as significant as it does in the picture.
