The Enchantment of the Central Tanzanite: A Gem Rarer than a Diamond
The Costanza Ring is a celebration of rarity and color. At the heart of this 18kt gold creation shines a tanzanite stone of exceptional quality, selected for its deep saturation ranging from midnight blue to vibrant purple. Those who approach this gem often ask themselves the question: is tanzanite or diamond better? The answer lies in exclusivity: the former is a precious stone mined in a single place in the world, making it infinitely rarer than a traditional diamond. In the constant comparison between tanzanite and sapphire, we choose the former for its ability to change hue depending on the light, offering a dynamic and sophisticated visual experience that only fine jewelry with tanzanite can provide.
The Diamond Crown: Eternal Light and Italian Design
The depth of the central gem is enhanced by a refined crown of pure diamonds, hand-set to create an endless play of refractions. These diamonds act as points of light that amplify the color of the center stone, transforming the Costanza Ring into a true masterpiece of fine jewelry. The 18kt white gold structure is the result of expert craftsmanship, where each prong is refined to ensure maximum safety and brilliance. For those seeking a matching set of rare beauty, the ring finds its ideal match in the Matilde Choker, creating a harmonious ensemble that represents the best of contemporary Italian gold jewelry.
