Celebrating Yellow

While gray stones are rare in the gemstone world, yellow stones are not. In fact, many jewelry brands feature yellow gemstones in their creations.

The gemologists from IGI Shanghai provided the images and information below, in celebration of Pantone’s color of the year, Illuminating Yellow, in gemstones.

1. Yellow Diamonds

Yellow diamonds have a pure, vibrant yellow or golden yellow color. Diamonds with enough saturation to reach the fancy yellow designation are are considered collectible.

The intensity of the color of a yellow diamond depends on the amount of nitrogen in the lattice. When nitrogen atoms replace certain carbon atoms in the diamond crystal, the diamond begins to absorb blue and purple light so the diamond takes on a yellow appearance to viewers.

There are many famous yellow diamonds.

Below, we present the Cora Sun Drop Diamond, a 110 carat pear-shaped golden yellow diamond which sold for $10.9 million – a world record price for a yellow diamond at auction – and the Golden Rooster Diamond, the largest diamond ever unearthed in China, and the largest yellow diamond in the world at 281.25 carats.

2. Yellow Sapphires

The main cause of color in yellow sapphires is the trace element iron.

In general, the higher the concentration of iron, the higher the saturation of the color and the wider the color range.

Yellow sapphires range in color from light yellow to canary yellow, golden yellow, honey yellow and light brownish yellow. The most popular shade is canary yellow.

Because they present more choices in terms of color variety and cutting potential, yellow sapphires may be considered great alternatives to yellow diamonds.

While the main source of yellow sapphires is Sri Lanka, they also originate in Tanzania, Madagascar, Thailand and Australia.

3. Golden Beryl

Emerald, Aquamarine and Golden Beryl are all members of the beryl family. Mineralogists and gemologists call Golden Beryl “Heliodor,” which is derived from two Greek words – helios and doron – which combine to mean “gift from the sun.”
