INFORMATION ON GEM QUALITY
For nearly four thousand years, the beauty of gemstones has been enhanced by various methods. Before modern stone-cutting techniques were developed, oils and dyes were used to bring out the color in stones. Since ancient civilization, emeralds have been soaked in colorless oil to make them appear more beautiful. These practices continue today.
It was also discovered that heating gemstones could produce changes in color. Legend has it that Marco Polo observed the application of heat to rubies in Ceylon and introduced the practice in Europe. The heating process is a practice that has been accepted worldwide and is permanent.
OGI Enhancement policy:
OGI selects only the finest gemstones for its jewelry. Our gemstones are inspected for quality, beauty and durability. We only use stones that meet our high standards for color, clarity and cut. We do not use any gemstones that have been enhanced to increase a stone’s weight, or to mask a potential blemish.
OGI diamonds have no enhancement
OGI does not use conflict diamonds
Rubies and sapphires may be heated
