The most popular and most valuable blue gemstones
The blue color of seawater and sky is extremely rare in natural stones. There are just a few kinds of stones that qualify as high-quality blue gems: evenly colored, hard, lucid, and, above all, with an incredibly clean, breathtaking blue color. This color is so rare that even hard minerals in blue color which are not transparent still can be more expensive than many translucent gemstones in other colors.
The unofficial king of blue gemstones is sapphire: a blue variety of corundum… although gorgeous corundum crystals in other colors (purple, orange, green) also are called sapphires. Naturally occurring, pure blue sapphires are very rare – in most cases, sapphires have a hue of some other color – green, violet, purple. Frequently the blue color of sapphires is “improved” by heating and other methods. It is considered that the world’s best sapphire was found for some decades in Kashmir. This mine is exhausted now and most of the mined sapphires are in private collections or lost.

While sapphire has an established value that lasts for many centuries, many other blue gemstones are recent introductions or simply, less known. Thus, the unexpected find of tanzanite in the late 1960ies brought a new kind of blue gemstone to the market and good marketing was essential to make it popular. Some other blue gemstones (the traditional gemstones – faceted and transparent stones) of high value are occasional blue diamonds (there is no certain location where they can be found on a regular basis), benitoites, blue beryls (bluer varieties of aquamarine), zircons, kyanites, the near-unique paraiba tourmalines, blue sapphires, and the extremely rare blue garnets. Just a few of these stones have a deep, pure blue color but each of them has a gorgeous shade of blue.
But there is another kind of gemstone – massive stones which are not faceted. Such stones can be translucent but not transparent. Could be that the bluest of them all is lapis lazuli – a legendary stone which has been mined for millennia in Northern Afghanistan. There are some more extremely valuable blue stones: turquoise (high-quality stone is extremely rare), light blue-green jadeite, larimar, chalcedony, chrysocolla, and many others.
A special place in this list is left for a peculiar material: blue amber. Few even know that it exists – but there are places in the world where such amber can be found.
Are these the only finds of unusual blue gemstones?
Wondermondo has to admit: this list has been rounded to a nice, traditional number of ten. Are there any other unique finds of blue gemstones? Yes: definitely. Some of these finds are:

- Ameib Farm – Namibia, Erongo. Well, this can not be called a mine or even a proper find. But… from time to time here are found light blue crystals of jeremejevite which are large enough to be used as gems. This is one of the rarest gemstones in the world. Only some of them have a blue color.
- Batalha mine – Brazil, Paraiba. The first find of the gorgeous Paraiba tourmaline – a seemingly glowing, electric blue tourmaline which was discovered in 1987. Later similar tourmalines were found in Nigeria and Mozambique.
- Bor Keo mines and Ban Gaew – Cambodia, Ratanakiri. Mines of the best blue zircon… which is not blue. Here is mined zircon that obtains beautiful blue color only after heat treatment.
- Daha kyanite mines and some other mines in Nepal, Karnali Pradesh. The only finds of high-quality kyanite gems in the world. This find is unusual – before this kyanite was considered to be of rather low interest to the gem industry but crystals from Nepal can be compared to the best sapphires!
- Los Chupaderos – Dominican Republic, Baoruco. This is a find of the best decorative, blue-colored, translucent concretions of a variety of pectolite: larimar. The Dominican Republic is the only source of this stone.
- Tranomaro grandidierite mine – Madagascar, Anosy. By far the best find of grandidierite – one of the rarest gemstones in the world. Tranomaro mine provides comparatively large, high-quality, lucid crystals that have a wonderful light blue-green color.
