A stone collector friend of mine says that the vintage coticules of days gone by had more garnets per square inch then the rocks that are harvested today. Would you say this is accurate ? It seems to me that the deposits are thousands of years old regardless of when they are mined. IOW, a coticule mined today is potentially as good as one mined fifty years ago ?
