## Description

This Direct Reading Specific Gravity Balance is Mineralab's assembly-ready version of Dr. Hanneman's design. What makes the Hanneman Balance special is its Direct Reading feature, i.e. no calculations, worksheets, or math are required - just read the Specific Gravity value that is printed directly on the Beam where the Counterweight assembly rests. Specific Gravity is a very indicative property for a Gem or Mineral, so that measuring for it will substantially narrow down your list of candidates in an effort to identify your unknown stone.

## Questions & Answers

**Q: How small can the stone be to register sg?**
A: About 0.6-0.7 carats.  Below this size the measurements are inaccurate.

**Q: There's something wrong with the balance I tried for many stone the reading has been incorrect big different from the correct**
A: We included the silvery colored, cylindrically shaped Aluminum Stick with the Balance, with known SG of 2.70 which is stamped on the side of the Aluminum.  Measure the SG of that.  You should get 2.70 or very close to that, which confirms that you are using the correct measuring procedure.  If you do not measure close to 2.70 SG, then compare your steps with the exact steps, in the exact order that we specify in the instructions.  If you contact us again, include the measured SG you got with the Aluminum stick.

## Customer Reviews

### ⭐⭐⭐⭐⭐ Very nice and easy to use.
*by L***N on June 7, 2023*

Easy to use. Instructions are clear and understandable.

### ⭐⭐⭐⭐⭐ Collector of Dr Hanneman's tools and writings
*by D***R on August 13, 2023*

This is Dr Hanneman's specific gravity machine, it works just as good today as when made and if taken care of will last a lifetime, they are no longer manufactured but I am a huge fan. Now there is much cheaper much smaller specific gravity setups you can purchase, most used his design and adapted them and made them more compact etc. Sadly Dr Hanneman's tools are not being made any longer since his death and some of his tools are so easy and work so well for amazing prices. This is in my opinion yes a gemologist tool that you can use daily but it's more a piece of history by a revolutionary. I have seen variable pricing and for a new unused in box tool the pricing starts at $100.00 and goes to $300.00 so it is priced in mid range honestly it is large and don't recommend taking it apart and putting it back together over and over but left out in designated area. If you just want something to check specific gravity there is plenty of smaller not nearly as expensive lab setups for sale. This is in my opinion a piece of history but Dr Hanneman's my hero. My dream is to manufacturer his tools with modern technology to fulfill his dream of creating gemology tools that anyone could afford not needing to invest tons of money just to start exploring gemology.

### ⭐⭐⭐⭐ Quality could be better
*by D***N on February 18, 2018*
