Your question does not provide enough to answer the
question with any degree of accuracy.
Emrald is a Type III gemstone, meaning it usually has eye visible
inclusions. "Some isolated inclusions" hints that the clarity of
what you are looking for would be considerably higher than
average...elevating the price.
The Guide, one of the most popular and accurate publications used in
the colored stone industry describes (accurately) the possible
colors of emerald as "Very strongly bluish green, bluish green, very
slightly bluish green, green, slightly yellowish green". These terms
are not subjective, but are well-defined by GIA, and part of the
standard nomenclature used by knowledgeable, educated jewelers and
colored stone dealers and cutters (including me). Please note that
the color of grass can vary a LOT, so my grassy green can be quite
different from your grassy green. This is why the terminology exists
and this is why it is important for us who buy, sell or have a
general interest in colored gems are well-advised to obtain the
requisite education. Slight color differences can have a huge effect
on prices, although different parts of the world have different
On a scale of 1-10, quality-wise, with 1 being lowest commercial
grade goods and 10 being flawless at 10X with top hue, tone and
saturation, a 3-4 carat Grade 6-7 will wholesale for around $1800 to
$2800 per carat. Grade 5-6 about half that. Top quality in that size
up to $10,000 or $11,000 per carat.
NOW...while cutting is ostensibly included in the grading of these
stones, I can assure you that you will RARELY if EVER find a high
quality emerald cut to correct angles for beryl. And when you do, in
good or better quality, you will learn that emerald can indeed be
very bright and very beautiful, and a far different animal than what
you usually see at the shows or in the colored stone dealer's trays.
I do not deal in high end emerald, but if you are looking for GOOD
to FINE materail, properly cut by a true expert, contact Doug Turet,
here on this list or firstname.lastname@example.org. I know Doug, but we have
no financial connection.
Good luck in your search.
