Masterfully faceted, the cut must maximize the effect of hue, tone, and saturation to optimize color.



Graded by eye and often containing inclusions, they define the character and natural origin of the gemstone.



Determined by a gemstone's hue, tone, and saturation. Emeralds range from a medium to darker green to blue-green.



Emeralds are less dense than a diamond and appear larger in the same weight, they are measured by millimeter size and carat weight.



Hue is the basic color. While an emerald's color might be described as green, more often gems are a combination of hues. For example, and emerald can have secondary blue or yellow color components that affect their beauty and value.


Tone describes how light or dark a stone's color is and influences the value of an emerald. The preferred tones for natural emeralds vary from hue to hue, but most fine emeralds have a medium to medium-dark tone.


Saturation describes how pure or intense a color appears, and it is an important component in determining an emerald's value. Regardless of a natural emerald's hue, higher and more intense levels of color saturation are preferred.

Ethical Origins


Ella Rose sources ethical, traceable and natural emeralds from our partner mines around the world. Our emeralds are in alignment with fair trade and environmentally responsible principles. We ethically source our emeralds from the three main global deposits found in Colombia, Brazil, and Zambia. An emerald's appearance is often associated with its mine and origin location. While emeralds are mined throughout the world, Colombia has historically produced the finest gemstones. Colombian emeralds are known to have a very warm and intense pure green color.


Emeralds are precious gemstones made up of the mineral beryl and owe their fine green color to the trace elements of chromium, vanadium, and iron. The varying presence of these three elements gives emerald its range of color.

Emeralds are commonly finished in a special cut designed just for this gem, namely the emerald-cut. The emerald cut is a step-cut or trap-cut featuring a rectangular or square shape with truncated corners. Emeralds are also cut into a variety of other traditional shapes such as oval, pear, and round.

Typically, emeralds contain inclusions that are visible to the naked eye. The presence of inclusions is universally accepted as these define the gemstone's character and confirm a natural origin. Emerald inclusions are sometimes described as garden-like and referred to as jardin, which means garden in French. Emeralds without any eye-visible inclusions are extremely valuable due to their rarity.
