Does anyone know of any Organization that sells authentic gold? What are some of the labels or awards credited to them to assure customer that they are selling authentic precious metals?

You can look at gold/silver that are minted by LBMA-accredited companies. Full list of these reuptable companies can be found here: http://www.lbma.org.uk/good-delivery-list

Since not all gold and silver will come with a certificate, especially for coins, it is good to have coins/bars that are at least minted by trusted refineries/mints mentioned on that list.

Simple authenticity test can be done at home using a magnet, weighing scale and a vernier caliper. Gold and silver are non-magnetic and each bullion bars has it's own dimensions, or diameter for coins. Weight should be as close to the stated weight denomination as possible. Gold is pretty much precise in weight as refineries will not give excess (free money).

If accessible, it is best to have a precious metal verifier. This is a quick way to test your metals. Xray Fluorescence machine can also be used but it can be costly for anyone. Another gadget would be an ultrasound machine which can be used for thick 1000oz good delivery bars.​​​

If you looking at Gold/Sliver as a form of investment, you can consider UOB's gold savings account. UOB has quite strong reputation, being one of the top 3 local banks in Singapore. Thomas (Mr. 15HWW) wrote about his experience buying gold from UOB, which you can read here if you're interested: https://www.my15hourworkweek.com/2015/10/21/how...
