Because high quality
precious gems are so valuable it's necessary to have
a universal method of assessing their worth for both
industry professionals and consumers alike. Although
what's commonly referred to as "The 4 C's" was
initially designed to grade and evaluate white
diamonds, variations exist for all high quality,
finished (as opposed to rough) gemstones.
The value of any one
stone depends on all 4 these measurements. For
example, a very large stone could be valued at a
lower cost than one that's smaller due to the fact
that it's lacking in one or more of the other three
categories. At Devonshire Consulting International
we will take the time to ensure you understand the
alternatives and get the best value whether you are
building or adding to a collection or simply looking
for the perfect showpiece for a piece of jewellery.
The first "4 C's" will
give you a great deal of information about a stone’s
characteristics and value, but they can’t begin to
describe one elusive quality – beauty. To do that,
you’ll need to experience the offerings from
Devonshire Consulting with your very own eyes.
