The small Gambia has its own archaeological mysteries. Northern coast of Gambia River is dotted with interesting megalithic landmarks - prehistoric stone circles. No one knows for sure what was the purpose of these structures.

Near Wassu village is located the richest site - 11 Wassu stone circles. These prefectly shaped stones have been erected here circa 750 AD.

Marquesas Islands

Few places in the world can compare to Marquesas Islands regarding the scenery. Marquesas are adorned with incredible cliffs, rock needles, ravines, canyons - for most part covered with a lush tropical forest or dry scrub. More charm is added by the picturesque villages with countless flowers and above all - welcoming and artistic people.

The archaeological heritage of Marquesas is not less charming. Quite a few megalithic monuments here are known tourist landmarks, but unknown number of mysterious stone structures and statues are hiding in the forests. A true fairytale land!

Happily the islands are not flooded by tourists - this place is very remote and the beauty of Marquesas is not much known in the world.

Gemstones belong to category of rare natural materials - materials which can be found just in a few localities of the world.

None can say exact number of kinds of gemstones. Creative lapidaries can make beautiful jewellery for almost any materials - but most videly used are some 30 kinds of gemstones.

More than 100 other kinds of natural stones are gorgeous gemstones as well, but are used less frequently due to their extreme rarity or rare occurence of gemstone quality samples.
