Gemstone Characteristics


Sapphires can contain fine rutile needles known also as “silk” in the jewelry trade. They can
give the stone a velvety, soft and shiny appearance.

Like "silk," some Sapphires also contain crystal inclusions that create a very unique pattern. These three dimensional patterns resemble human "fingerprints."

These images were taken in-house. The image above shows both inclusions combined within the gemstone. Most gemstones contain identifying inclusions.

Wait. Do you have a commercial Laboratory report with that?


GIA & Gemworld information

Robert M. Shipley established the Gemological Institute of America (GIA) in 1931. GIA is the world’s foremost authority on diamonds, colored stones, and pearls. Gemstones are identified and graded by GIA so that they can be classified according to price.

In 1982, Richard Drucker introduced the world's gemstone industry a colored gemstone pricing guide, now known as GemGuide. The publication, which is recognized as the industry leader for gem pricing and market information, is used for valuation and information in more than 40 countries by jewelers, appraisers, and as a reference in legal cases involving valuation.

In conjunction with material quality and pricing, labor also plays a substantial role in the creation of a finished jewelry product. After all, jewelry is art and is only as good as the artist. Gellar's Blue Book to Jewelry Repair & Design states the manufacturing and labor costs associated with production.

We used all three resources along with the current market to assess the value of an item.
