The PREMIER brand for Gemological Instruments. This is a GIA GEM DiamondLite.

PLEASE NOTE: This has had certain electrical components removed including the light source and is therefore being sold for parts ONLY. This comes with a Power adapter & cord which were not photographed.

This is ideal for parts or for a "light-box" kind of set-up for all those electrically inclined. This DiamondLite retailed for about $500 when it was introduced.

Here is GIA's Info on the DiamondLite:

DiamondLite simulates the north daylight needed for accurate color viewing of diamonds as well as colored stones. Balanced and diffused cool white light fills spacious working area. Customers who find that color adds warmth and character to diamonds can compared color subtleties of mounted or loose stones. Adjustable translucent tray at top lets you view stones with light coming from behind and below. Ideal for Yellow, brown and gray diamonds. Also built in is a separate long-0wave ultraviolet lamp to check fluorescence, a quality which can enhance diamond appeal for some customers, and help you close the sale.
