EnerGold 24-Karat Gold in a Bottle Colloidal Gold (200 PPM) - Made With The Highest-Purity Commercially-Available 99.99%-Pure Gold! With concentration of 200 parts per million at the minimum and particle size less than 2 nanometers, EnerGold 24-Karat Gold in a Bottle Colloidal Gold retains its characteristic beautiful color ranging from bright-pink to red-violet due to the scattering of light by its gold particles, similar in principle to why the mineral iron is the reason for the reddish hues of human blood. EnerGold 24-Karat Gold in a Bottle Colloidal Gold is made in three distinct batches: - one with particle size 2 nanometers - one with particle size between 2 and 12 nanometers - one with particle size between 13 and 24 nanometers Then, after their completion, the three batches are combined, rendering a single batch containing gold particles ranging from 2 to 24 nanometers. Our Inimitable Ultraconcentrated Formulation Is Made With Our Specially-Designed Proprietary High-Voltage Equipment Using: - 99.99%-Pure Gold - Distilled Water - Trace Amount Of Our Own Monoatomic Gold/ORMUS For Stability Of The Ultraconcentrated Suspension (See our listing for our World's ONLY Pure-Gold-Based & -Infused Monoatomic Gold/ORMUS) IMPORTANT: EnerGold 24-Karat Gold in a Bottle - because it is a delicate supersaturated solution of gold atoms in suspension - should never be frozen. DO NOT ALLOW YOUR PACKAGE TO SIT IN THE COLD TEMPERATURES IN YOUR MAILBOX. If frozen, our beautiful formulation will collapse, and the gold particles will amass into dark-purple clumps in a near-clear solution (Please see photos). If you cannot be home to receive your package, leave a note for your mail-carrier to hold it at the post-office for later pick-up.
