Estate Gemstone Value Guide
Fine Colored Gemstones: Using this Estate Gemstone Value Guide you can see
why fine colored gemstones like ruby, sapphire, emerald
and alexandrite can achieve or possibly surpass the Cash
Market Value of fine diamonds. Most
“fine” colored gemstones are natural but may
have industry acceptable treatments (as long as they are
disclosed) of heat or in the case of emerald, oil.
Additive treatments that add color, change color or mask
color like irradiation, diffusion, coating and dyeing are
considered more invasive and possibly are not permanent.
These treated stones will have a
“significantly” lower value. Use
this Estate Gemstone Value Guide to get and approximate
value of gemstones.
Any Estate Gemstone Value Guide will tell you the key factor in determining a fine colored stone’s cash market value is the “color”. In the case of ruby the finest rubies are red, like a stop sign. For example; purplish-red, or orangish-red ruby will have a lower value. Brownish-red will have even a lower value. Hue is caused by trace elements in the gemstone crystal, pure primary colored gemstones have just one coloring element, for example fine green comes from chromium. Having just the one trace element is rare, so pure green emeralds are worth more than brownish-green emeralds. Medium dark tone green emeralds are worth more than light green elements which are light, because there is not enough of the trace chromium. The same goes with the other fine colored gemstones. The finest blue sapphire will have a pure blue hue, with no secondary color. A purplish-blue or greenish-blue sapphire will have a lower value than a pure blue one. The next factor is brilliance which is connected to both the proportions and the clarity. A well cut ruby with very heavy inclusions will not appear brilliant because the many inclusions inside the gemstone will block the light. A clean ruby which is not well cut will also have low brilliance but in this case because of the wrong proportions. So ideally gemstones will not only have pure color, will be clean and well cut, however this is rare. Natural fine gemstones only rarely meet all three of these which is why they enjoy very high Cash Market Values. Use this Estate Gemstone Value Guide and learn approximate value of gemstones that you are interested in.
Reminder: A vital point to understand about a Retail Appraisal Price is that it is used for insurance purposes, to replace the item at full retail price in a retail store in the case of a loss. Appraisal Price cannot be confused with the Cash Market Value which is the real market price someone will pay.

Colored Gemstones: There are so many different gemstones that can be set
into jewelry and the Cash Market Values vary considerably.
You can use this Estate Gemstone Value guide to get an
idea of the cash market value. The key factor in
determining a colored stone’s cash market value is
the color. In the case of tourmaline the finest ones
are red, like stop sign red. A brownish-red or
purplish-red tourmaline will have a lower value. The
same goes with the all the other fine colored
gemstones.
The next factor is brilliance which is connected to both the proportions and the clarity. A well cut amethyst with very heavy inclusions will not appear brilliant because the many inclusions inside the gemstone will block the light. A clean amethyst which is not correctly cut will also have low brilliance but in this case because of the wrong proportions. So ideally, gemstones will not only have pure color, will be clean and well cut. Some of the more expensive colored stones are readily available in smaller sizes, but the when size gets over 5 carats the price per carat can jump very high.
