The dark blue birthstone refers to sapphire, which is the traditional birthstone for the month of September. Sapphires have been prized as gemstones for centuries and carry rich symbolism and meaning.
What is the dark blue birthstone?
The dark blue birthstone is sapphire. Sapphires belong to the corundum family and consist of aluminum oxide. Corundum is the second hardest natural mineral after diamond. Sapphires form over millions of years when aluminum and oxygen are subjected to high temperatures and pressures deep beneath the earth’s crust.
Sapphires come in a range of colors, including pink, yellow, green, orange and purple. However, the most coveted and valuable shade is a rich, deep blue. These dark blue stones epitomize the beauty and mystery of sapphires.
What makes sapphire dark blue?
The vivid dark blue color of sapphires is caused by the presence of trace amounts of iron and titanium. These elements cause the crystal lattice structure of aluminum oxide to absorb light in the red and orange-yellow spectrum, leaving behind blue light to be reflected back to the eye.
The more iron and titanium in the stone, the darker and more saturated the blue color. The most highly desired shade is known as cornflower blue, a medium-dark tone reminiscent of the blue cornflower. Stones that are too light or too dark are considered less valuable.
