I have never seen a Lemon Colored Jade in any quantity. I have seen
a few obects and rough items of jadeite that could possibly be called
a yellow green color.
Gem traders are constantly looking for materials that are
inexpensive and can simulate another established gem in the market
place. I would sugest you use a set of hardness tools to determine
the hardness of the material and find a way to determine the specific
gravity of the material. These two pieces of data should help you to
narrow your decision. I use the "Gemstone & Mineral Data Book" by
John Sinkankas to narrow down the field from there.
Be advised that this only works for natural materials. There are so
many laboratory grown materials and enhanced materials being used for
beads and carving that identification becomes very confusing. Even
people that have been studying gems for years are having trouble in
todays market place. I look for obvious indicators that I weigh
against my knowledge and experience. If the material does not fit
into what I know I either do not buy or only buy a small amount for
testing. In my experience it is better to be safe than sorry.
Scammers exist at every level of the gem trade. Your own knowledge
and a relationship with a supplier that will allow returns on
improperly labeled material are your best defenses.
