An 18x13mm rectangular cushion ruby zoisite with 0.32 carats of round ruby in 18K yellow gold over sterling silver ring measuring approximately 0.76 inches long by 0.57 inches wide - the ruby zoisite ring where natural ruby accent stones reinforce the red element already present within the center stone. Ruby zoisite carries its own opaque ruby inclusions; the separate ruby accent stones deepen and extend that red presence. Not sizeable.
