- [Narrator] Rihanna wore a $130,000 Chocolate Diamond

And these Chocolate Diamond earrings that J-Lo likes

when brown diamonds would have never made the red carpet,

selling for six times less than they do today.

Diamonds get their color by how they're formed,

whether it was a different element that got pulled

Like boron, which gives diamonds a beautiful blue hue,

or maybe it was close to a natural source

Whatever the reason, diamonds come in a rainbow of bright,

beautiful colors, and then there are brown diamonds.

For centuries, brown diamonds were cheap.

So jewelers didn't want them, especially when they

could use brighter pink, blue, or yellow diamonds.

Instead, brown diamonds were used as tools to drill through

Today, it produces more diamonds than any other mine

And while it's been said that the quality of Argyle stones

companies have still managed to find a market.

One company in particular being Le Vian Corp.

- We found these beautiful, natural fancy color brown

diamonds that were coming out of the Argyle Mine

of Australia that were quite underappreciated.

Le Vian trademarked the name Chocolate Diamonds in 2000,

giving it a monopoly on the market for these particularly

Soon after this rebranding, Chocolate Diamonds took off.

Google searches for "Chocolate Diamond" went

from virtually zero in 2007 to 400,000 in 2014.

- The price of Chocolate Diamonds has risen

were worth about $1,500 per carat, but now many sell

Le Vian isn't the only company that has tried

Jewelers like Zales have called them other names like

but Chocolate was the name that really took hold.

Given its success, we asked Eddie how the name came about.

- The name of Chocolate many people think, "Oh, yeah

because these are brown, so they put chocolate,"

but the reality was there was a friend of mine, Bill Furman,

who used to come every day after work and visit me,

and he would always bring me artisan chocolates,

and he would always talk about the special powers

And so when we did the branding of Chocolate Diamonds,

the obsession that people have to the food chocolate.

- [Narrator] Le Vian says just four percent

The diamond needs to fall within a specific shape

between C-4 and C-6 on the industry's color scale.

So more like a milk rather than a dark chocolate.

Once the right stones are ready, it's time to make jewelry,

- Many years ago, diamond cutters began to experiment

with different ways of placing the facets on these diamonds

so that they didn't appear overly dark, and it allowed light

which gave all of these wonderful sensations.

- [Narrator] But Chocolate Diamonds may become harder

However, John doesn't think that will stand

- It would seem even at a point where Argyle may no longer

be mining, that the groundwork has been laid,

that the interest in a range of colored diamonds now exists,

I think will sustain and probably only grow more.
