【Available 9/10 at 10 PM】 Brazilian Rainbow Aquamarine (Iridescent Aquamarine) 1.507ct Loose Stone
In the past, aquamarine was used by fishermen as an amulet for safe voyages. It is a mineral known as "beryl," the same as emerald, and those with this ocean-like blue to light blue hue are called "aquamarine." This particular aquamarine is characterized by its rainbow-like brilliance and is known as Rainbow Aquamarine or Iridescent Aquamarine (trade name).
