Diamond Disc Kit
Click images to enlarge
The Diamond Disc Kit is used  to quickly and easily capture good
images of loose diamonds. In many cases, the images are able to
clearly show the size, nature and location of the grade-setting inclusion.

In the image left, back row, left to right can be seen the Stone Leveling
Device, and two diffusion tubes. In the front row, left to right is a stack
of three riser discs, a two-sided Diamond Disk (with loose PR cut
diamond), and the Girdle Viewing Disc with two stone holders.
In practice, a loose diamond is placed in the small depression in the Diamond Disc.  The disc is
two-sided, with different sized depressions on either side, allowing for diamonds from  about 3mm to
over 15 mm to be photographed.
A set of three riser discs and two diffusion tubes are supplied in the kit.  When working with very large stones, it may be
useful  to use these along with the TruLevel to vary the camera distance from the stone for the desired results.  In larger
stones, these accessories will allow you to make an image of the entire stone or to focus on minute internal or external
details which may be important.  The TruLevel seen above right has a groove on its bottom plate that fits on the diffusion
tubes for easy centering. It is shown atop one of the diffusion tubes. Click to enlarge.

The camera can be used directly atop the Diamond Disc or it can be used with the TruLevel and one of the diffusion
tubes.  Your choice will be controlled by the size of the stone . In use, the time from stone paper to captured image is
less than 30 seconds.
The circular groove accepts the Stone Leveling device (right) , which has a small plunger that orients the table of the
stone in the proper position. The Leveling Device is then removed, and the camera placed on the disc.  The camera is
centered on the diamond by the circular groove, and the image is made. Click images to enlarge.
Girdle Viewing Disc
The Girdle Viewing Disc is useful to document features such as girdle chips, naturals, girdle inscriptions or other
features of interest.  The stone is placed in the end of a supplied dop stick with a small amount of sticky wax or
modeling clay.  The dops and disc will handle stones from 3mm to over 14 mm in diameter. When the camera nose is
placed in the groove on the disc, the dop is held in place and may be turned with your free hand to show the desired
feature.
The images above are of the girdle area of a 5.5 mm square PR cut diamond (left), and a
