A 2.25 carat marquise blue chalcedony with 0.12 carats of round white zircon and 0.22 carats of round neon apatite in 18K yellow gold over sterling silver ring - the chalcedony ring where neon apatite accents add electric blue-green sparkle around the soft milky blue center stone. The contrast between chalcedony's soft translucent quality and neon apatite's vivid saturated color creates visual energy. Marquise cut gives the chalcedony directional form.
