Start with Certified Diamonds
The #1 of all diamond buying tips to keep in mind is to buy certified diamonds only. If you are buying a loose diamond, or any piece of diamond jewelry, make sure the diamond is certified. Ideally too, the diamond certification should be provided by one of the four top gemological laboratories in the world:
Premium diamond wedding rings and engagement rings too are crafted with diamonds which are certified by one of these laboratories.
The only exception to this recommendation is if you are buying a diamond antique engagement or wedding ring, an estate ring or a gently used ring that contains a diamond which has not been previously certified.
Because diamonds which are already mounted cannot go through the grading and certification process, these rings should come with an appraisal conducted by an unbiased third party who has no relationship to the seller.
The best diamond ring appraisals by far are those which have been issued by a certified American Gem Society gemologist appraiser. When you shop for diamond rings that are not made with certified diamonds, a reputable appraisal and a certificate of authenticity will ensure that you are purchasing a first rate diamond and that the ring is reasonably priced.
The Best Diamond Grades
As a general guideline to go by, the best AGS and GIA diamond grade parameters to stay with whether you are shopping for loose diamonds or a diamond ring are:
GIA = D to I
AGS = Zero to 3.49
GIA = IF to SI2
AGS = Zero to 5
GIA = Excellent to Good
AGS = Ideal to 4
Diamonds which go beyond these grades will have noticeable color tints, diminished brilliance and fire and visually apparent inclusions. Diamonds too which have low clarity ratings may also have durability risks due to inner fissures or cracks. To see diamond grading charts for GIA and AGS diamonds, take a look at EWR's page about Diamond Cut Clarity and Color Charts.
For some types of diamond cuts, only the highest grade diamonds are recommended because certain types of shapes - like emerald diamonds - can highlight even the slightest flaw. Other types of diamond cuts - including the brilliant round - have a little more give and can actually hide small flaws. But, even with diamond cuts that are more forgiving it is still best to stay within the grade parameters listed above.

Additional Diamond Buying Tips
Plenty of reputable diamond retailers sell certified diamonds. Unless you are buying an antique or gently used ring crafted with a diamond that has not been certified, there is no reason not to buy a certified diamond. GIA certified diamonds, and those available through the three other recommended laboratories, are widely available in an almost limitless selection of cuts, shapes and carat sizes.
Stick with retailers that offer at least a 30-day refund policy - both for loose diamonds and quality diamond rings.
If you are on a strict budget, a more affordable diamond with a slight color tint is an option - the color tint can be hidden or minimized if the diamond is set in a yellow gold ring.
Diamonds which have the maximum amount of fire and brilliance include: brilliant round, princess, radiant, and Asscher diamonds. If you are looking for a unique diamond with plenty of flash too, a pear diamond will fulfill both of these qualities.
It is estimated that anywhere between 1 to 15% of the diamonds on today's market still fall under the category of conflict diamonds. To find out how to ensure your diamonds are conflict-free, check out this page on non-conflict diamonds.
And last on this list of diamond buying tips, but definitely not least, is that while large center stone diamonds are quite stunning, they can overwhelm smaller more delicate hands.
Consider the size of the hands and fingers of the
person who will be wearing the diamond. For smaller hands diamonds from
anywhere around 0.40 to 1 carat look lovely, while for those with
larger hands 0.80 to 2.5 carat diamonds will suit wonderfully too. The
perfect diamond will
compliment the hand without looking bulky or over sized (bling
lovers - disregard this advice!).
