HELP PLS I NEED THIS BY THE END OF THE DAY I WILL GIVE BRAINLIEST Your friend says they bought a new ring with a ruby (corundum) in it for $2000 but you think they got cheated. You ask to borrow their pretty red ring and promise to give it back. It has a non-metallic, glassy luster. You test the ring and find that it scratches to glass but gets scratched by a piece of topaz you have. When you scratch it on an unglazed porcelain tile, you barely see a brown line. You tell your friend the bad news. What do they really have? Answer using claim, evidence, and reasoning.
