Costanza Tanzanite Ring

“There is nothing that is not made easier through perseverance and familiarity and training. We can change thanks to training; we can transform ourselves.”

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.

THE TANZANITE

THE TANZANITE

A gem expert used these words to describe this stone: “Tanzanite looks like a sapphire would like to be”. It is a very precious stone, since it is considered a thousand times rarer than diamonds. Its name comes from Tanzania. Along the slopes of Kilimanjaro, in fact, there is the only deposit in the world. It is said to represent vitality and energy and it brings great benefits to the body and the soul when worn.

Size Guide for Rings


Fingers tend to become smaller in colder temperatures.
Indeed, we advise you to measure fingers at the end of the day, when they are largest.

 

  • Take a length of string or cut a strip of paper no more than 1cm wide (a slightly less than half an inch)
  • Wrap it around the largest part of your finger
  • Use a pen to mark the point on the string or strip of paper where it forms a circle
  • Pick the marked strip or string of paper on a flat surface
  • Using a ruler, measure the distance from the end of the string or paper to the mark you make
  • Compare your measurement with the chart below to determine your ring size
 

If your size is between two sizes or if you are unsure of your size, opt for the largest of the two.
