Read the description carefully
The ad does say they are very small in a few places. Anyone complaining about size did not read what they were buying.<br /><br />I have mined Herkimer diamonds, found only in Herkimer, NY. What distinguishes them from regular quartz crystals is that each have 10 facets and double terminations.  The smaller they are, the more likely they are to be crystal clear. The larger ones are more imperfect and sometimes contain sediment.  We were fortunate enough to find 4 golf ball sized “diamonds”, but they were not as pretty as the tiny flawless specimens we have. Odd that these are made and/or sold out of Texas.
