Hi I purchased an "investment grade" ring from Craig 2 years ago for $10,995.00 and added a $3000 SS ring box for a total investment of $13,995.00....I purchased Craig's SS ring book at the time of purchase as well...I was forced to sell the ring due to personal issues.Craig was advocating that rings were a terrific investment and his book supported this...less than 4 months after buying the ring from Craig he re-purchased for $6000!!!!!!!! I lost $8000 in 4 months on what was touted as being a great investment.....be careful cautious and always get a second and third opinion or offer...DO NOT SELL CHEAP!!!!!! cheers, Ryan
