- Jadeite (Wikipedia)
Jadeite is a pyroxene mineral with composition NaAlSi2O6. It is hard (Mohs hardness of about 6.5 to 7.0), very tough, and dense, with a specific gravity of about 3.4. It is found in a wide range of colors, but is most often found in shades of green or white. Jadeite is formed only in the subduction zones of continental margins, where rock undergoes metamorphism at high pressure but relatively low temperature.

Cape Verde (/ˈvɜːrd(i)/, VURD(-ee)) or Cabo Verde (/ˌkɑːboʊ ˈvɜːrdeɪ/ KAH-boh VUR-day, /ˌkæboʊ -/ KAB-oh -, local Portuguese: [ˈkabu ˈveɾdɨ]), officially the Republic of Cabo Verde, is an island country and archipelagic state of West Africa in the central Atlantic Ocean, consisting of ten volcanic islands with a combined land area of about 4,033 square kilometres (1,557 sq mi). These islands lie between 600 and 850 kilometres (320 and 460 nautical miles) west of Cap-Vert, the westernmost point of continental Africa. The Cape Verde islands form part of the Macaronesia ecoregion, along with the Azores, the Canary Islands, Madeira and the Savage Isles.
