SAPPHIRE FACTS AND HISTORY
SAPPHIRE QUALITY FACTORS
Given the lack of a standardized sapphire grading system, it is important to know what to look for when purchasing sapphire jewelry.
- Sapphire Color: This is the most important quality factor when it comes to grading a sapphire. The most highly valued blue sapphires are velvety blue to violetish blue, in medium to medium dark tones. While most people are familiar with the blue variant of sapphires, they do come in almost every color. The only color corundum stone that the term sapphire is not used for is red, which is considered a ruby. The other colors for sapphire are yellow, purple, orange, and green. Each color has its own quality variations. Preferred sapphires have strong to vivid color saturation, regardless of hue.
- Sapphire Cut: This is one of the most important factors in appearance. Like diamonds, sapphires are cut in the same shape styles. In terms of grading the cut of a sapphire, there is a lack of standardization because each stone is cut to maximize it’s color. To achieve the best overall color, maintain the best proportions, and retain the most weight possible, cutters focus on factors like color zoning, pleochroism, and the lightness or darkness of a stone.
- Sapphire Clarity: This refers to the inclusions. Unlike diamonds, where the clarity is graded based on their clarity at 10x magnification, sapphires are looked at based on their visual appearance. Sapphires typically have some inclusions but if they have extremely high clarity, they will be rare and very valuable. The price can drop if the inclusions threaten the stone’s durability.
- Sapphire Carat Weight: This allows for precise measurements. Sapphires tend to be heavier than diamonds. Therefore a 1 carat diamond is going to appear bigger than a 1 carat sapphire. Sapphires can range in size anywhere from a few points to hundreds of carats. Most commercial-quality blue sapphires weigh less than 5 carats.

THE IMPORTANCE OF SAPPHIRE CERTIFICATION
Often times when purchasing a fine quality sapphire it will be accompanied by a certificate. There are countless laboratories that grade sapphires, some of which are good and some not so good. G.I.A (Gemology Institute Of America) is known as one of the top labs in the world who grade precious gemstones. Two other very respected laboratories that grade only colored stones (rubies, sapphires & emeralds) are G.R.S (Gem Research Swiss-Lab) and AGL (American Gemological Laboratories).
When looking over a lab report (certificate) you can trust, remember that origin is a very important factor as well as treatment, both of which should be indicated on the certificate (lab report). We do not recommend purchasing a larger fine sapphire without a TRUSTED lab report! There has been many instances of innocent victims being fooled by bogus lab reports claiming false information.
