Rare half-pink diamond weighing 37.4 CARATS unearthed in Botswana

A rare and remarkable half-pink, half-colorless rough diamond weighing 37.41 carats (7.5g) was discovered in the Karowe Mine in Botswana.

The diamond is one inch long and has a ‘sharp’ partition between the dusty pink and transparent segments.

However, jewels are exceptional because temperature and pressure conditions have to be just right for them to form.

Experts were of the view that it could be one of the most significant pink diamonds in history.

In this connection, co-founder of diamond cutting firm HB Antwerp, Oded Mansori said, “This stone has the potential to become one of the most important pink diamonds ever polished.”

He further explained, “And our deep understanding of the manufacturing process will allow us to capture its vibrant color to the fullest extent possible.”

It has been observed that the diamond commenced life more than three billion years deep within the Earth's intense heat and pressure, around 93-124 miles beneath the surface.

Carbon atoms are fused together in a tight lattice and are brought to the surface through volcanic eruptions.

Meanwhile diamonds can obtain color through impurities that get locked inside the lattice as it forms.

Pink versions are the product of distortion, meaning their structure has been modified through geological processes.

It has been observed that too much deformation turns the jewels brown. This means that the right balance has yet to be reached.

The experts have confirmed that the pink section was formed first, and the colorless half developed with time.

Experts from the Gemological Institute of America (GIA) said that similar diamonds they have examined were much smaller, weighing no more than (0.4g).

The mine’s major finds include the 1,758-carat Sewalo, the 549-carat Sethunya, and more recoveries such as 2,488-carat Motswedi.

Mostwedi, unveiled by Canadian mining firm Lucara, is the second-largest rough diamond ever recovered.

Nonetheless, the discovery offers a rare, large (37.4-carat), bi-colored (half-pink) diamond in Botswana and is considered a significant source of rare gems.

The Eternal Pink is graded as “internally flawless”, and its color level is so rare that it’s shared by only about four per cent of all pink diamonds.
