Kyanite from Nepal

Introduction

Kyanite from Nepal stands out as a gemstone with its vibrant blue tones and distinctive characteristics. This mineral forms under intense pressure in metamorphic rocks, showcasing color shifts from deep sapphire-like shades to softer sky blues. Beyond its appearance, Nepalese kyanite holds notable metaphysical properties. Note: Claims about metaphysical properties are rooted in traditional beliefs and lack scientific validation.

Comparison to Other Blue Gemstones

Few gemstones boast a truly deep, saturated blue. Sapphire leads the pack, thanks to its remarkable hardness and sparkle. That said, options for that intense blue are limited. Topaz usually leans toward lighter blues, and even the irradiated London blue topaz hits more of a mid-range tone. Spinel in cobalt blue is uncommon, and when you do spot blue spinel, it often carries a grayish undertone.

Quality of Nepalese Kyanite

Kyanite frequently displays a blue reminiscent of sapphire, though a medium blue is standard. Its color isn't always even, often showing patches or streaks. But here's where it gets interesting: Recent finds in Nepal are elevating kyanite's reputation with top-tier quality. Unlike material from Cambodia or Burma, which seldom rivals sapphire, Nepalese kyanite can echo the rich blue of premium Kashmir or Ceylon sapphires.

Discovery and Mining in Nepal

High-quality kyanite surfaced in Nepal back in 1995. You'll find it in regions like Dolakha, Rasuwa, Dhadhing, and Jajarkot. Per Nepal's mining department, four small-scale operations run in Daha and Suneri in Jajarkot, plus Barah in Aachham District. Output remains modest and is likely to stay that way.

Physical Properties

Kyanite consists of aluminum silicate, sharing that makeup with andalusite and sillimanite. Its triclinic crystal structure sets it apart, leading to unique traits. One standout feature is its varying hardness - soft at 4 to 4.5 on the Mohs scale when cut along the crystal's length, but tougher at around 6.5 when cut across. It features a glassy to pearly sheen.

Availability and Sizes

Typically, kyanite gems don't come in large cuts - a 2-carat piece counts as substantial. Yet, we've come across exceptional Nepalese kyanite with strong color, tipping the scales at up to 10 carats.
