Precious Stones
The concept that some gemstone types are considered 'precious', while others are only 'semi-precious' is actually a recent innovation that dates back to the 19th century. Most people incorrectly assume that this concept is one that dates back hundreds of years as a 'tradition'. The term 'semi-precious' was first used in 1858 in reference to gems 'of less commercial value than a precious stone'. Precious stones were known as the 'precious four' gems, which included fine sapphire, red ruby, green emerald and of course, diamond (all colors including white, yellow, red, blue, green, champagne, cognac, chocolate and etc). These four types of precious stones typically command high prices due to their extraordinary color, brilliance and/or extreme rarity.

However, as of more recent times, the distinction between precious and semi-precious gems is no longer recognized by most professionals in the gem and jewelry trade. In fact, the 'traditional' list of precious gems has been expanded from 4 gem types to numerous gem types. Many of the newer members of the precious gem group include precious topaz, precious pearl, precious opal, precious coral and more. Other varieties of colored stones are actually rarer and more precious than any of the original precious gem members, such as red beryl (bixbite), color-change alexandrite, red spinel, tanzanite, demantoid garnet and tsavorite garnet, for example.

It is fair to say that we have now reached the point where precious and semi-precious has become meaningless. In fact, the United States Federal Trade Commission (FTC) periodically considers banning the use of these terms and the American Gem Trade Association (AGTA) already includes the following text in their Code of Ethics: "Members should avoid the use of the term 'semi-precious' in describing gemstones". Although these organizations in the USA have begun taking action on changing the use of the terms described, the rest of the international gem and jewelry trade are still continuing to use the terms, though more loosely. It is fair to say that the original precious four gems are still considered by most to be precious, while most other varieties of colored stones are typically still being referred to as 'semi-precious' gems.

finally bought the last rock to complete my ring idea; needed another white one after giving the big diamond to my daughter. a diamond that size is out of my retired-school-teacher budget, so i bought a white zircon. went back to the same place that i got my loose sapphire-- great selection, good prices, good delivery!

Size and Weight

Gems are always measured in Millimeter (mm)

Dimensions are given as;
length x width x depth,
except for round stones which are;
diameter x depth

Select gems by size, not by weight!
Gem varieties vary in density, so carat weight is not a good indication of size

Note: 1ct = 0.2g
