Q & A

What are diamonds known for in terms of their physical properties?

Diamonds are known for their scintillating sparkle, astounding hardness, and rare beauty.

How are diamonds formed?

Diamonds are formed over eons deep inside the Earth's upper mantle where immense heat and colossal pressure cause carbon atoms to crystallize into diamonds.

What geological phenomenon brings diamonds closer to the Earth's surface?

Powerful volcanic eruptions bring diamonds closer to the Earth's surface through narrow cone-shaped rock formations called kimberlite pipes.

Where are the most significant diamond deposits found?

The most significant diamond deposits are found in Siberian Russia, Botswana, the Democratic Republic of Congo, Australia, and certain Canadian territories.

What is the process of diamond mining like?

Diamond mining is an intensive process involving heavy machinery, explosives, and massive drills to extract diamond-rich ore from kimberlite pipes.

How are diamonds separated from waste rock?

Diamonds are separated from waste rock through a process that includes crushing, scrubbing, screening, and advanced sensor-based sorting.

What is the purpose of analyzing raw diamonds after extraction?

The purpose of analyzing raw diamonds is to determine the ideal cut strategy for each stone based on individual qualities like color, clarity, shape of crystallization, and location of inclusions.

How does advanced scanning technology contribute to the diamond cutting process?

Advanced scanning technology can map inclusions inside rough diamonds in 3D to identify the most valuable portion, which helps cutters maximize carat weight, quality, and value of polished diamonds.

What is the goal of cutting and polishing raw diamonds?

The goal is to optimize light refraction, sparkle, and fire by creating intricate symmetrical facets that refract and bounce light, with exact angles, symmetry, and alignment to maximize brilliance.

What are the steps involved in the diamond cutting process?

The diamond cutting process involves cleaving or sawing the rough diamond along precise crystalline planes, attaching it to a dop stick, and then fating by expert gem cutters who carve intricate symmetrical facets onto the stone.

How are diamonds polished to create sparkle?

Diamonds are polished by methodically polishing each facet to a mirror-like finish using diamond grains mixed with olive oil on polishing laps made of soft metals, which are spun at high speeds.

What are the four C's used to grade diamonds?

The four C's used to grade diamonds are color, cut, clarity, and carat weight.

How have advancements in technology impacted the diamond industry?

Technology has evolved to grow diamonds in laboratories through more efficient versions of the heat and pressure process, offering an ethical and eco-friendly alternative to mined diamonds.

What is the significance of the diamond industry in today's world?

The diamond industry is significant as it represents a global market driven by our enduring obsession with diamonds, combining ancient geological forces, cutting-edge technology, and craftsmanship.
