COLORED GEMSTONE CLARITY GRADING
CLARITY: Clarity is the second most important factor in colored gemstones.
The guidelines used for clarity in a diamonds and colored gemstones are different. Colored gemstones have more inclusions than diamonds, are not so neat, and there are certain gemstones that hardly ever appear clean.
MdMaya Gems uses the following clarity scale when grading gemstones.
Sometimes these inclusions are what make stones valuable (silks in rubies, the cat's eye effect in the alexandrite, etc.).
Setting aside translucent and opaque gemstones, the first classification to take into account is:
EYE CLEAN: Appears clean to the unaided eye. (Type 1, 2 and 3)
HEAVILY included: prominent inclusions that have a negative effect on appearance or durability.
SEVERELY INCLUDED: prominent inclusions that have a severe effect on appearance or durability or both. (Type 1, 2 and 3).
A clear example: Whilst in aquamarines the term slightly means that they show really small inclusions that are very difficult for the naked eye to notice (without using a magnifying glass), when talking about emeralds slighty means notable sized inclusions that can be easily seen.

Thoughts alouds of a gemologist about gems scams, the relationship that we humans have with gems and jewels, and of course, about feelings.

Lo primero que buscamos en las piedras preciosas es su belleza. Pero la belleza es subjetiva y es muy difícil de clasificar.
Una cosa que he aprendido con el tiempo es que cuando se venden piedras preciosas sueltas, los compradores suelen ser coleccionistas de gema o bien van a usar la gema para hacerse una pieza de joyería a medida; un anillo de compromiso, de boda, o algo muy especial. En cuyo caso tienen clarísimo el color que están buscando.

The first thing we look for in precious stones is their beauty. But beauty is subjective and is very difficult to classify.
One thing I have learned over time is that when loose gemstones are sold, the buyers are often gem collectors or they will use the gem to make a custom piece of jewelry; an engagement ring, a wedding ring, or something very special. In which case they are very clear about the color they are looking for.
