Color Variation & Stone Notes (Please Read)

These connectors use simulated gemstones, and slight color variation is normal and expected.

• Purple stones and red stones may appear very similar when viewed face-up.
• The best way to confirm color is by flipping the stone over. 
• Once set into the bezel, the gold-filled or sterling silver metal and natural shadowing can make stones appear darker.
• They are different stones, even if the differences are subtle once set.
