This perfect chrome specimen is a pleasure to look at. It is an ultra-high purity chromium sample obtained using chemical vapor deposition. Its purity reaches 99.999+%, far exceeding the electrolytic chromium or ordinary metallurgical materials we usually use. This huge sample weighs more than 200 grams. It is undoubtedly a very rare collection.
