PhosView

This compact, self-contained screening device is designed to allow parcels of polished diamonds to be quickly analysed to determine if they contain potential HPHT synthetics.

PhosView cannot be used to screen for CVD synthetics, simulants or treated stones. If any potential HPHT synthetics are indicated built-in manipulator arms may be used to manually separate these from the remainder of the parcel. PhosView can accept loose diamonds from 0.3 points to 1 carat. Some set jewellery pieces may also be tested.

Diamonds screened with PhosView must be colourless or near-colourless.

PhosView is simple to operate: melee are placed in a removable sample tray which is part of the PhosView sample drawer. Once the drawer has been closed a single button is pressed to start a special video mode which will indicate potential

HPHT synthetics. If required one of the manipulator arms may be used to manually move these to a separate area of the sample tray while viewing them in real-time.

If rings are being tested they may be placed on a conical mount in the sample drawer which is then closed. A single button is pressed to start a special video mode which will indicate potential HPHT synthetics. Rings may be rotated to check for any potential HPHT synthetics in real-time. Other jewellery pieces may also be handled subject to their configuration and dimensions.

Any stones which are indicated as potential HPHT synthetics should be submitted for further testing.

PhosView Frequently Asked Questions

Can other gemstones be tested on PhosView?

PhosView is for diamonds only.

What size range of diamonds can be tested?

0.003ct to 1ct round brilliant. For fancies the smallest linear dimension should be 0.6mm and a largest linear dimension 6.4mm.

What colour range of diamonds can be tested?

Colourless and near-colourless.

Do you provide training for PhosView?

The PhosView instrument is very simple to use therefore a manual and a quick step guide are sufficient.

Can I use PhosView to screen for possible CVD synthetics, simulants or treated stones?

No, it is not possible to use PhosView to screen for anything other than HPHT synthetics among colourless or near-colourless diamonds.

PhosView Operation Frequently Asked Questions

How long does it take to screen a parcel?

Once the parcel has been loaded into the sample tray it takes around 20 seconds to determine if any potential HPHT synthetics are present.

How many stones can the sample tray hold?

This depends on the size of the stone. The main section of the sample tray is about 16cm2 in area and the diamonds to be screened must be presented in a single layer. The smaller section of the sample tray into which potential HPHT synthetics may be moved is about 2.7cm2.

Can I check bangles?

No, it is not possible to check bangles with PhosView.

Why are two manipulator arms provided?

These allow left or right-handed operators to use the instrument. It is not necessary to use both manipulator arms together to move a stone.

Why can’t I use tweezers to move the stones?

PhosView contains an ultraviolet light source; it is not possible to use tweezers with this instrument without exposing the operator to hazardous optical radiation. No attempt should be made to modify or remove the manipulator arms or to open the instrument.

Can I save images?

Yes, images can be saved. This functionality requires a user-supplied keyboard and mouse. A memory stick will be required to transfer the images to a PC.

Can I use PhosView to screen for possible CVD synthetics, simulants or natural diamond treatments?

No, it is not possible to use PhosView to screen for anything other than HPHT synthetics among colourless or near-colourless diamonds.

Does PhosView require a network connection?

For normal operation PhosView does not require an internet connection but it is good practice to connect the device to the internet periodically to allow software updates to be downloaded.

Why do you supply a test stone with each instrument?

We have found that when first using the PhosView instrument it is very helpful to have phosphorescing stone to practice with.
