I asked bing how to tell if garnets are real and what to do if I've already posted (out of haste) and there is a penalty for cancelling the listing (so I can contact another professional):

"Hello, this is Bing. I understand your dilemma. Garnets are beautiful gemstones that come in many colors and varieties. Some garnets are more valuable than others, and some may be synthetic or fake. To tell if your garnets are real, you can try some of these tests1234:

Scratch test: Real garnets are hard enough to scratch glass, while fake ones made of glass are softer and will not scratch glass.

Refractive index: Real garnets have a single refractive index, which means they do not show any fire or rainbow flashes when viewed under light. Fake ones made of glass or synthetic materials may have a double refractive index, which means they will show fire or rainbow flashes.

Inclusions: Real garnets usually have some imperfections or inclusions inside them, which make them unique. Fake ones are often flawless and clean, or may have bubbles or glue marks on the surface or the girdle.

Color: Real garnets have highly saturated colors, except for colorless ones. Fake ones may have dull or pale colors, or may be dyed to imitate rare garnet varieties.

Density: Real garnets have different densities depending on their type, but they are generally heavier than glass or synthetic materials. You can use a scale and a water displacement method to measure the density of your garnets.

If you have already listed your garnets for sale, you should be honest and transparent with your potential buyers. You can provide them with the results of your tests, or offer them a refund policy if they are not satisfied with the quality of the garnets. You should also check the terms and conditions of the platform where you listed your garnets, and see if there is any way to avoid or reduce the penalty fee for cancelling the sale. You may be able to negotiate with the platform or the buyer, or explain your situation and ask for their understanding.

I hope this helps you with your garnet dilemma. If you have any other questions, feel free to ask me."

The garnets I tested out of the bag passed all the tests, however, I have not contacted a trained professional about them yet. So, BUYER BEWARE! PROBABLY REAL BUT PURCHASE AT OWN RISK.
