About the Legend- Inventor of The Sherlock Holmes detector 2.0
Zvi Yehuda
Mr. Zvi Yehuda is a world renowned Scientist and Pioneer in the Diamond and Jewelry
industry. His inventions have paved the way for generations to come. Here are just a few
of his inventions to date:
1965—Laser Drilling of Diamonds. Some diamonds contain an internal black spot
imperfection, and by using a laser he was able to drill into the black spot and clean it.
1977—The Yehuda Diamond Colorimeter, a device that examines rough diamonds and
predicts their color after polishing. The Colorimeter diagnoses the entire normal scale
of the D -K colors.
1982—Yehuda Clarity Enhancement- In the process he invented, a visible inclusion
(called a feather) within the diamond is rendered invisible to the naked eye. He found
a way to insert a microscopic amount of material that has the same optical properties
as a diamond into the inclusion, using a high pressure and high temperature process.
2013-Present—The Sherlock Holmes Synthetic Diamond Detector - a device which
detects CVD and HPHT synthetic diamonds in matter of seconds.

The YEHUDA Sherlock Holmes User Manual
The Yehuda detector detects lab grown Diamonds –loose diamonds,
mounted in Jewelry, single stones, large parcels and any size Melee. It
detects both CVD and HPHT lab grown diamonds.
This detector is designed to detect only white diamonds within D- K
colors. Lower color diamonds and fancy color diamonds should not be
tested.
Diamond simulants- CZ, Moissanite, diamond coated CZ and Moissanite
can be detected fairly easily when they are tested loose.
As for other gem stones –we currently do not have enough information.
Diamonds can be tested loose, in a thin plastic bag, or mounted in
jewelry. They cannot be tested if covered by a thick plastic or glass!!
Please visit our website www.yehuda.com. You can find a helpful video

Now you can start performing tests with the detector.
You can test mounted diamond jewelry, loose diamonds or loose
diamonds in a plastic bag.
DO NOT TEST DIAMONDS IN A PLASTIC BOX (THE BLUE BOX) OR
COVERED WITH A THICK PLASTIC OR GLASS. If you test diamonds in a
plastic bag- make sure it is thin and clean.
The best way to test loose diamonds is uncovered in a tray or on the
glass base.
In any event –the detector detects only diamonds that it can SEE from
the top. If a diamond is covered by another diamond - it will not be seen.
The same goes for jewelry - only diamonds facing the top camera will
be seen.
If you test a ring or any other jewelry make sure to test it a few times
from all angles and lying flat on the bottom.
Insert the diamond/s or the jewelry piece into the center of the drawer
above the glass square. You can tap on the screen before starting the
test in order to use the autofocus mode.
You can use manual focus by sliding the slider on the bottom of the
screen. When the slider is located around the middle - the focus is on the
bottom of the tray. (Testing loose diamonds)
When the slider is all the way to the right - the focus is on the top of the
drawer. (Testing rings)
You can use the autofocus by taping on the screen or the manual focus
by using the slider.
The detector will remember the focus for your next test.
If you do not tap the screen or move the slider- the focus height will
remain the same for the next test.
When using the autofocus mode the test may take a few seconds longer
than when using the manual focus.
The reason is that with the autofocus mode the camera needs to find the
focus. When using the manual mode, the camera already knows where
the focus is.

When inserting jewelry into the drawer you need to press the RING
icon in order to perform the test.
When inserting loose diamonds into the drawer –you also need to
press the RING icon as well in order to perform the test. If the resulting
image shows too much red and you cannot distinguish between the
diamonds –redo the test by pressing the LOOSE DIAMOND icon
When you test with the RING icon, the detector is set to be more
sensitive.
This is the reason that you may see small red dots around the jewelry.
Please ignore them.
When you get the result of either mode (loose or jewelry) you can see a
picture of the tested diamonds/jewelry.
Checking jewelry
It is recommended to check rings using any of the ring holders and lying
on the glass table.
Make sure to test the jewelry from all sides.
When using a ring holder, you may cover the bottom lamp with the
black square. In this case the result pictures will be more vivid.
You can use it or not use it as per your preference.
