Your cart is empty.Use this kit with _your_ Electronic Carat Scale to measure the Specific Gravity of Gems and other small items. Please note that the Kit does not include the Scale, but this SG kit is "Universal" in that it is compatible with most any compact digital Carat scale. It is adjustable in 3 different dimensions for Scales of varying height, depth, and width. The Kit includes everything you need to measure Specific Gravity, except for the Scale and the Water. Note: There are two versions/sizes of this kit. Choose our "Bench Scale" version of the kit, instead, for use with larger, standard size Lab or Industrial scales (search SGK-B).

The water-weight suspension frame is poorly made. The foot/bottom points slide freely allowing the entire frame to cant at odd angles. Should have been squared and secured to base to prevent canting/leaning when weighing.

Everything that was advertised was there. In examining the spreadsheet, the print is extremely small. It needs to be a larger font or show a link to an electronic version for download so I can print it at the larger font.

It works well with my carat scale and is very useful. SG readings look pretty accurate, and between this and a refractometer, I can make an accurate gem species determination 90% of the time. However I question the value for the dollar amount - nearly $100 for something that was obviously manufactured for considerably less. Also somewhat concerned as it is a bit fragile -- not a tool I can leave out, but needs to be put away each time to keep it safe.

Excellent hydrostatic tool for gemologists and anyone interested in getting specific gravity of gemstones. Very nice quality, very accurate with 2 or 3 different types of scales we used to test, and this unit is very well priced. I highly recommend both the Universal Specific Gravity Kit and the seller for quality.Robert James FGA, GGInternational School of Gemology
