Full-Cataloguing
A natural, round Fancy Vivid Blue diamond is an extraordinary find for any jewellery enthusiast or gem collector. It becomes even more remarkable when its visual appearance reveals such a rich, ink-blue colour.
The story of blue diamonds begins on an ancient ocean floor, where the element boron, responsible for their colour, started its journey deep into the Earth’s mantle. Research suggests that blue diamonds formed at far grater depths than most other diamonds, making them some of the deepest natural materials ever brought to the Earth’s surface.
Round brilliant diamonds are far less common than fancy shapes in the Fancy Colour diamond category, since the round brilliant cut does not retain colour as effectively as modified fancy shapes. Achieving a Fancy Vivid blue grade in a round diamond is therefore exceptional, requiring remarkable strength of colour, beautifully demonstrated by this diamond.
According to data from the Fancy Color Research Foundation, this diamond has an estimated Rarity Ratio of approximately one in nine million.
A stone combining natural blue colour, Fancy Vivid saturation, a pure blue hue and high clarity is an extraordinarily rare and important diamond. At 1.35 carats, this Fancy Vivid blue diamond is a true treasure of the Earth, carrying within it secrets from the deepest layers of our planet. It is a wonder to behold and to own.
