Prongs that hold the stone are often made of platinum (even on yellow
gold rings) because of its special features. With 4 prongs, you will
show off more of the diamond, but 6 prongs will hold the diamond more
securely and are highly recommended to avoid losing the stone. The
Tiffany style is a classic example of a prong setting, usually 4 or 6
claws on a half rounded band. This simple and basic ring is a great way
to show off your rock, since it is lifted up away from the finger and
is ‘floating’ in space.
There are for’s and against’s for this style of setting. Many
people like to be able to see the side view of their diamond and it is
commonly thought the open sides allow more light to reflect through the
diamond. But if you have followed the Pricescope and
the Cut Adviser
system and purchased an exceptional ideal cut then only the light that
comes in the top can come out the top. The light that goes in the back
goes out the back.
Another problem is these settings usually touch or are very
close to the rear of the diamond – dirt gets wedged in and even a
jewelers steam cleaner can’t dislodge it. This dirt kills the
brilliance of even an ideal cut diamond.
For diamonds set in prongs we recommend a medium to thick
girdle to minimise the risk of chipping the edge of the diamond. You
should insure this style because of the risk of chipping and loss if a
prong is broken off (especially in 4 claw settings).
