In fact, no matter how old a diamond is, it has a certain recycling value, but relatively speaking, the recycling price of diamonds below 30 cents is not high, but the recycling price of diamonds above 30 cents is basically ok. If it reaches one carat, the recycling price is also ok.
The price of diamond recycling mainly depends on the 4c parameters of diamond (carat weight, color, clarity, cut) and whether there is fluorescence. Take a carat of GIA diamond as an example, the recovery price is generally around 20,000-60,000. Hope to adopt, thank you.
