Is there any app, tool, or pricing system that tracks diamond price fluctuations incrementally, not in real time?
Example: if the base price is $1,000, the price only updates when it passes a certain threshold, like $1,100. Any movement between $1,000–$1,099 (e.g. $1,050 or $1,060) does not change the price.
Once it goes above $1,100, it recalculates using the next tier, say $1,200.
Does anything like this exist, or how do people usually handle this?
