I recently was in Mexico and bought a 75 point emerald with 8point
diamonds on 24k gold ring.

What does the 75 point and the 8 point mean and how can I figure out
how much these 2 gems (at this size) should cost?

I am trying to decided if I got a good deal or not. The emerald is
square, light in color and clear and was imported from Columbia.

Any help would be appreciated!

Teri

Points are a weight measure. You've probably heard of carat when people talk
of stones, especially diamonds. There are 100 points to a carat. So a 75
point emerald is 0.75 of a carat, whereas the 8 point would be 0.08 of a
carat.

Values of emeralds depend on a bit. How light coloured is the stone? Are
there any inclusions (cracks, fractures or other imperfections)? By the way
it's rare, and therefore generally more valuable, to have a totally clean
emerald.

A "point" is .01 carat (1/100th). 75 points is 3/4 carat. 8 points is .08
carat, just under 1/10th of a carat. The value of the stones is dependent
upon the size (carat weight), of course, but also the cut and clarity.

24k jewellery is very hard to find! I've seen it, and it's an intensely
golden yellow in color, and a bulk of the 24k items out there don't tend to
have gemstones in them because of the softness of the gold not being the
most secure place to seat a valuable gem. Are you SURE you have 24k
jewellery?! Especially a purchase in Mexico...con artists abound! Could it
be 24k over sterling? I would have this examined by a jeweller if I were
you. Most will even give you a little education on your piece and further
explain things like The 3 C's (carat weight, cut and clarity).

Good luck...

In addition, there are 5 carats (not karat - that's gold purity) in a
gram. A US nickel (5 cent piece) weighs about 25 carats = 5 grams.

Actually it is quite common to use 24kt gold in Mexico, Central and
South America. It is more expensive of course but often preferred. I
bought 2 24kt emerald rings when I was in Bogota. One at H. Stern, the
other a random store on the street(whose name escapes me) where all
the emerald jewelry stores are located. This was 12 years ago and I
have had no problems with either the stones or the settings except
that one of the rings has bent slightly and isn't completely circular
but you can't see that on my hand. I prefer 24kt because I like the
color but North American jewelry manufacturers don't use it much
because they say it's too soft.
Be careful not to expose the emeralds to cleaning solutions or
chemicals. Most emeralds are routinely treated (unless you bought an
extremely expensive stone and were told by the store that the stone is
untreated)that is, fracture-filled and the filling can leak out.

A point is to a carat as a penny is to a Dollar. 100 points = 1 carat. Your
75 point stone is 3/4 carat.

Hi Teri,

I missed your original posting somehow.

To address the point that Jeffrey didn't, the only way to tell whether you
got a good deal is to have the ring appraised by a certified independent
appraiser. Without doing that, you really have no way of knowing whether
the emerald is natural, synthetic, or imitation, and anything about the
quality of the diamonds.

Natural Emerald can run anywhere from $200 - $2000/ct in the size you're
describing. Synthetics are less, and imitations MUCH less.

8pt diamonds are not particularly expensive, but can range from industrial
grade (a few dollars per carat). The lowest gem-grade diamond (I = included)
in that size would cost about $18/each. Top-quality gem grade diamond in
that size could cost you as much as $120 each.

So you can see the huge range possible -- that's why an appraisal is the
only way to tell.
Best of luck,

KG

Or perhaps you've just forgotton seeing it.

One consequence of the moderated nature of rec.crafts.jewelry, and the fact that
it accepts posts only in plain ascii text, which means most postings are short
and take little space on the server, is that most news servers offer this group
a rather unusually long message retention time. Some of the news servers keep
messages available for as much as several months, are at least several weeks.

In this case, Terri's original message was posted to the group on July 1st,
almost two months ago now.
