The sellers represent the color shift of Alexandrite in the form of a percentage. A 100 percent change is the perfect type of stone. And it's recommended to ignore stones that display 30 percent or less of change.


Determine The Clarity


The clarity of the colored gemstones adds to its elegance. As long as the gemstone is opaque and absorbs all light. The light that passes through the gemstone influences its elegance.


External and internal characteristics influence the clarity of the gem produced by itself. It happens while the shaping of the gemstone or as a result of the cutting procedure.


The internal spots or lines are the characteristics referred to as inclusions. But, these markings make each stone special. The stone is more desirable when there is a lesser number of inclusions. Inclusions can also interfere with the passage of light through the gem. This decreases the clarity and value of the stone.

The inclusions present in Alexandrite are parallel rutile silk or negative crystals. These rutile inclusions produce an extra optical illusion termed as a cat's eye effect in a stone. Gemstones with a cat's eye effect have a higher price per carat due to their relative rarity.


Look Into The Cut


Gem cutters are always striving to create pleasing and cheap combinations. These include color, weight, and a safe design for mounting. During formation, Nature causes the limited size of a gemstone. For e.g., large-scale Alexandrite is rare. Whereas, large and beautiful amethysts are available,


Sparkle adds charm to a well-cut polished gemstone. The cut of a colored gemstone defines its type and way of formation. Some cutters today might still be using convex or concave facets. They use it to form colored gemstones like small sculptures.


You'll find alexandrite stones in a range of market cuts. This stone looks beautiful in every way, from simple cabochons to fancy shapes. It is available in mixed cuts, including step-type pavilions and genius crown cuts. The concentric rows of parallel needles in step cuts look interesting.


But the pleochroic aspect of Alexandrite renders it a tough stone for the cutters. They've got to steer the gem in a way that shows the color transition by its crow. A carved stone has green and purplish-red pleochroic tones on the surface.


Select The Carat Weight


Carats determine the weight of the gemstone. Besides the carat weight. The jewelry industry also tests colored gemstones by dimensions in millimeters.


When combining colored gemstones there is a point to focus on. Consider millimeter dimensions for rings, earrings, or other forms of jewelry.


Most of the cut and shaped alexandrite stones are available in carat weight of less than one carat. The larger sizes of this gemstone are rare and very costly. So, if you want a gemstone that weighs three or four carats, you will have to pay more on alexandrite price per carat.


Size influences the value of Alexandrite, as mentioned above. Top-quality natural gems have a selling price of up to $15,000 a carat in sizes up to one carat. Over a carat, prices vary from $50,000 to $70,000 a carat!
