Please note when viewing high quality gemstones on the net there are certain limitations:
1. Most monitors display images
at varying dots per inch (dpi) and are not color-corrected.
2. GIF and JPEG formats compromise quality.
3. Netscape and Internet Explorer browsers can only
"see" 216 of 256 colors.
Since every system, browser, and monitor is different, we don't know if what you and we see are the same.
