Step 1
Find a stone with good color. A deeper blue aquamarine is ideal and many stones are heated to obtain this shade. Find out if the piece that you are purchasing has been heat-treated. Aquamarines without any shades of green are the most valued type.
-
Step 2
Check the clarity. The highest quality piece of aquamarine jewelry will be completely transparent and free of inclusions.
-
Step 3
Choose a higher carat. Aquamarines are naturally found in larger sizes, so the higher carat stones will have the best color and clarity.
-
Step 4
Purchase white-gold, silver or platinum to complement the gemstone. Gold aquamarine jewelry is less aesthetically pleasing than using these other precious metals.
-
Step 5
Watch the terminology used when buying aquamarine jewelry. For example, a "Brazilian Aquamarine" is actually a blue topaz. Also, a gemstone known as "Siam Aquamarine" is heat-treated blue zircon.
-
Step 6
Ask for an appraisal. Although many pieces of aquamarine jewelry are affordable, you still want an appraisal certificate to know the value of the jewelry.
