Emerald of course, but also the whole range of other beryllium colors, such as red or pink bixbite, pale pink morganite, beryllium green of any color saturation, as well as blue-green (Paraiba) or aquamarine. These varieties of beryllium are rare, and the size of natural stones does not exceed 1-3 carats. Therefore, pure samples of standard color weighing more than ten carats can indeed be classified as collectible stones.
In addition, the technology makes it possible to grow synthetic two-color beryls with a color that is not characteristic of natural stones, but is more common in other minerals. These examples include bright scarlet hack tourmaline and deep blue Paraiba tourmaline, which are highly valued by jewelers for their incredible rarity and unique color.
Such materials are popular with creative jewelry companies that offer jewelry of new and original design to sophisticated buyers.
