Crystalla

From BoardGameGeek:

In Crystalla, you want to create a valuable arrangement of seven types of crystals: rubies, tourmalines, diamonds, and more. You start with a tableau on which you will eventually place twelve crystal cards. These cards are divided into two shimmering segments that show different colored types of gemstones. Each crystal is scored in a different way and is worth more or fewer points either separately, together, or arranged in a certain pattern. An interactive selection mechanism not only determines the cards to be placed, but also sometimes distributes additional crystal pieces that further enhance your own work of art by covering a segment - or clouding over the crystal-clear structure of other players. Whether with a sparkling row of diamonds or shimmering emerald flowers, who will create the work of art that scores the most points?
