We have two status classifications for our items: Available and On Hold.
“Available” means that the item is in our office and can be shipped immediately.
“On Hold” means that an item is not available for immediate delivery. On Hold can mean a few different things. The item may be out on preview with another client or a client is arranging payment to purchase the item and has reserved it. On Hold can also mean the item is at one of our trade shows, with a retail store, or out to another dealer on consignment. The item may not sell and could return to Available status within a short period of time. Our database is ‘real time’ so we show the active status for all of our inventory items 24/7.
If you see an item that you are interested in, you can still go through the steps of buying the item online to ensure that you will be the next person in line should the item become Available. If the item is not returned to us, we will contact you to let you know that your transaction has been voided.
If you wish to purchase an item we suggest you call us and ask for more details about its status.
All of our sapphires come with a comprehensive identification report issued by our staff gemologists. These reports are not marketing documents, but professional certifications that conform to industry standards and are recognized by all insurance companies.
We use the latest scanning technology to give us valuation and comparison analytics that were never before available in the gemological industry. We are the only company on the internet that provides this advanced documentation for each of our gemstones. While these reports are not complimentary from other gemological laboratories, we provide these documents for all of our sapphires at no additional charge.
Each report is accompanied by a dust cover which explains the definitions and stone characteristics listed on the report.
Some stones are accompanied by a third party laboratory report in addition to our in-house documentation. These stones have been randomly selected from our inventory to be audited by an independent laboratory to maintain our position of quality control and reporting. Not all stones have been evaluated by a third party laboratory. Gemological testing reports from these institutions are expensive and testing our entire inventory would prove to be cost prohibitive.
The Natural Sapphire Company employs the same GIA (Gemological Institute of America) certified gemologists that third party laboratories employ, use the same technical equipment and have the same standards in reporting. Our internal reports are as accurate and guaranteed as any high quality third party laboratory.
We recognize the reporting from the following independent laboratories, all of which are members of the LMHC (Laboratory Manual Harmonization Committee): The GIA (Gemological Institute of America), AGTA (American Gem Trade Association), Gubelin Lab (Switzerland) and SSEF Laboratories (Switzerland).

Please select what metal type you want to display. You can choose multiple metal options if you would like to view more than one.
Gold can come in a range of colors. The most common are white, yellow, and rose gold. The percentage of pure gold to an alloy in the metal will determine the “karat” of the metal as well as its color. Gold is measured on a karat scale of 24 parts. 14K gold has 14 parts gold per alloy; meaning it is 58.33% pure gold. 18K gold has 18 parts per alloy; meaning it is 75% pure gold.
Platinum is usually cast with an alloy like iridium or palladium. The platinum number corresponds to the percentage of pure platinum in the metal. Platinum 950 is 95% pure platinum.
Palladium is a platinum group metal, or PMG. It is increasingly being used as a substitute for platinum and white gold because it is harder and less expensive.

If you do not know your ring size and would like to measure your finger, follow the instructions below.
1. Wrap a piece of string or a strip of paper aroud your finger.
2. Mark the point where the two ends meet.
3. Measure the string or paper against a ruler to find the circumference of your finger.
4. Divide that by 3.14 to find the diameter of your finger.
5. Look up your ring size using the form above.
Sapphires are found all over the world but only a few locations produce gem quality stones. Learn more about origin on our Education page here.
Did you know that almost all sapphires are treated to improve their color, clarity and even size? It is extremely important to know if a sapphire you are considering to purchase has been treated. All treatments dramatically change the value of a gemstone.
The Natural Sapphire Company deals only with the finest quality sapphires. Almost all of our sapphires are untreated, meaning the sapphire has undergone no enhancement and is 100% natural.
Below are images of treated stones to give you a better idea of the dramatic shift in appearance after heating with flux-additives. Treatments can take very poor quality rough and transform it into a stone with a much better appearance. However, the quality and value of the stone is still very low.
The chart below features common gemstone shapes. The most popular shapes for colored gemstones are round, cushion, emerald, radiant and princess. If you would like more information regarding the characteristics of each shape, please call us to speak with a gemologist who will be happy to help you select your sapphire.

Below are common terms and characteristics used to evaluate and classify the cut of a gemstone.
While diamonds have an internationally established grading system, there is no standardized method to analyze clarity in sapphires and other gemstones. No natural gemstone is flawless. Diamond clarity is graded under 10x magnification. If viewed under 20x magnification a diamond with FL (Flawless) clarity would still have inclusions. Natural untreated sapphires inherently have more inclusions than diamonds at the standard 10x magnification. Therefore, we grade our sapphires at eye level, as almost no natural untreated sapphire would be considered flawless under 10x magnification.
At The Natural Sapphire Company we grade the clarity of our sapphires on a comparative basis. We have over 70 years of experience dealing exclusively with sapphires. We have borrowed some of the standard diamond grading terms and applied them to sapphires to better assist customers who may be familiar with diamond clarity terminology (example: VS1, SI2).
Below is the scale we use to grade clarity in our sapphires at eye level :
We offer a full selection of sapphire earring settings. Earring styles vary widely, but most earrings fall within four design categories: stud, drop, hoop and chandelier. Stud sapphire earrings are simply a pair of sapphires set in a small prong earring setting. Bezel set stud sapphire earrings are also a popular style. Stud earrings are a very classic style and are great for all occasions. Drop sapphire earrings generally have two sections: one part that hugs the ear and a second part that hangs below the ear and is often moveable. Drop earrings are very versatile and can be worn with casual or fancy attire. Hoop earrings are a circular piece of metal that is either unadorned, or set with sapphires, gemstones or diamonds. Chandelier earrings are a more ornate variation of the drop earring. They are often multi-tiered and are larger than regular drop earrings. Chandelier sapphire earrings are very elegant and are wonderful for formal occasions.
