Aquamarine Gemstone Guide:  Aquamarine Facts & How to Buy Aquamarine Jewelry

What is Aquamarine / What are Aquamarine Gemstones?

Aquamarine is a variety of beryl (as is emerald).  It is considered a semiprecious gemstone and rates a 7.5-8 on the Mohs scale of hardness, behind such well-known gemstones as diamond, sapphire, ruby and topaz.  

14K Genuine Aquamarine and Diamond RingAquamarine, as the name implies, is generally a light blue gemstone that can range in color from very, very pale blue to blue-green.

Aquamarine is also the official 'modern' birthstone for the month of March, as adopted by the American National Association of Jewelers in 1912.

Aquamarine is considered a Type 1 clarity gemstone by the Gemological Association of America (GIA), which means it is usually free of inclusions, with excellent natural clarity.  Inclusions are interior cracks and fissures which can both weaken a gemstone's structure as well as adversely affect its clarity.

Buying Aquamarine Jewelry

Aquamarine gemstones with deep color are rare, and therefore, more pricey.  Typically, however, aquamarine jewelry is purchased expressly because of its attractive pale blue color, excellent clarity and suitability for jewelry.  You should have no problem finding decently sized aquamarine jewelry, in a light blue shade that suits you, for a relatively affordable price.

Aquamarine Jewelry Shopping Tip:  If you want to buy light blue gemstone jewelry, in general, rather than aquamarine jewelry specifically, try pricing blue topaz jewelry too.  The color spectrum of aquamarine versus blue topaz is very close, and you will find blue topazCushion Cut Aquamarine Drop Earrings in 14k White Gold jewelry is a bit more affordable than aquamarine jewelry.

Aquamarine Color Enhancement Treatment

Aquamarines are sometimes heat treated (heated to high temperatures) to enhance color. With respect to aquamarines, heat treatment is used to obtain a more pure color rather than a deeper color.  For example, an aquamarine with a bit of a greenish cast may be heat treated to bring its color to more of a true pale blue (not necessarily a darker blue).

Such heat treatments are permanent and will not fade nor wear away with time.  However, any clarity or color enhancement treatments undergone by gemstones should be disclosed by the jewelry seller.  If you're considering an online purchase, be sure to read all information presented with respect to the particular piece of jewelry you're considering.  Reputable jewelry sellers freely divulge such information online; it's up to you, as the buyer, to be sure you read and understand the disclosed information and ask any questions if you need clarification.
