Doves by Doron Paloma London Blue 18K White Gold Diamond Ring R9175LBBT

The London Blue 18K White Gold Diamond Ring you're referring to is a luxurious piece featuring both London Blue Topaz and Sky Blue Topaz, set in 18K white gold. 

This combination of the rich blue tones of the topaz stones and the sparkling diamonds set in white gold gives it an elegant and timeless look. The London Blue Topaz is typically a darker, deeper blue, while the Sky Blue Topaz offers a lighter, brighter contrast, creating a stunning visual appeal.
