We’re actually in agreement, ie we are both recommending some of the
honest sellers on ebay. My reply recommending ebay to Robert was for
coloured stones as well as diamonds and in many of the gems I buy,
you can tell from the picture whether it’s the actual gem. Gems such
as various jaspers, opals, malachite, carnelian, rhodonite,
rhodochrosite, moonstone, etc that have distinctive marks, it’s easy
to tell whether it’s the actual gem.
I’m fortunate in that I’ve not really been burnt by my ebay
experiences, as I always apply certain rules which I stick to. If
I’m not happy, they get sent back for a full refund or replacement
and so far I’ve always been pleased. I am very choosy in what I buy.
I’m no gemologist but have a healthy interest in gems and have read
about and known the four C’s of diamond buying for a number of
years, so whilst I couldn’t pinpoint a colour grading (apart from
being able to tell when a diamond has a yellow cast to it), I can see
when a diamond that’s supposed to be VVS turns up as I2-I3 because of
clearly visible inclusions to the naked eye, so again if I’m not
happy it goes back.
When I said about comparing the picture with the gem that’s
delivered to you, I was talking more about the coloured, distinctly
marked gems as stated above rather than diamonds, but if you are
buying diamonds either through ebay or through some other online
source where you don’t get to examine the stone first, you should be
clued up to the point where you can see if the stone falls within the
grading that you bid on and as Robert is wanting to buy diamonds,
presumably he has enough knowledge to know if what he gets is what
the description says.
As I say, it’s about being informed, having realistic expections and
using common buying sense.
