1, this carat is not bought casually, so we should protect our customers. The key is to maintain what you say. What I want to say most is not diamonds, but greetings and concern. That is to build trust from life, and time proves everything.
2, and don't think about this customer who drives. I have never heard that the customer is God, but you should give God guidance. What is good, why is good, and why is the price of 1 carat? There will be differences. What major do you eat?
Don't you use cutting mirror, magnifying glass and waist prism as tools? Colorimetric paper and calorie explanation, do you think these are more conducive to persuading customers?
4, praise customers, but also look for a real advantage, clothes or hair, luggage and other advantages that can be found can be the beginning of your trust.
Anyway, I don't know if it's useful to have a little personal feeling for you. I also met people who bought 600,000 carats. Everyone is the same, just to see if we can win the trust of our customers.
