In the clear waters of a tropical lagoon, it is hard to draw a line between blue and green. Near the shore, the water is almost aquamarine; in deeper areas, it becomes a rich turquoise. These transitions are what the color of lagoon tourmaline brings to mind.
Some stones draw you in with a light, cool shade; others with a deep blue-green color. Some people prefer the blue component, others the green. This is part of the pleasure of choosing: finding your own balance.
What Does the Name Lagoon Mean?
Lagoon is a trade name describing the color of a tourmaline. It is not a separate mineral variety or a designation for a single deposit. The name brings together stones with shades reminiscent of seawater: turquoise, greenish-blue and blue-green.
Unlike names with strict boundaries, this one rests largely on a visual impression. Two lagoon tourmalines can therefore look noticeably different, and each can be beautiful in its own way.
Emerald Cut: Geometry and Color
These colors are especially expressive in an emerald cut. The rectangular outline, cropped corners and long step facets give the stone a composed appearance and emphasize its color.
As the stone moves, broad flashes of light alternate with darker reflections. Its shade takes on different qualities: at times lighter and more transparent, at others deeper and more saturated.
The open table offers a view into the interior of the stone. For those who enjoy precise geometry, this cut allows the tourmaline itself to become the main focus of a piece of jewelry.
Finding Your Shade
Start with a color you want to keep looking at. A light bluish-green tourmaline may suit a delicate piece of jewelry, while a saturated turquoise can create a more noticeable accent.
Then look at the stone in daylight and indoor lighting, face-on and at an angle. Notice its proportions and shifting reflections: whether you enjoy the elongated shape, how the color is distributed, and which facets come to life as it moves.
There is no single right shade for lagoon tourmaline. Its appeal lies in finding the combination of blue and green that you want to wear.
