I bought a diamond ring at Faxin Jewelry Store. The name is AU750 diamond ring. It is colorless and has feathers. The total mass fraction is 1.3349. How much is it worth?
Mainly depends on the size of the diamond, 18K gold, one gram of 290 yuan. Diamonds can be measured with calipers, 15 minutes 3.4MM, 20 minutes 3.8MM, 30 minutes 4.3MM, 40 minutes 4.8MM, 50 minutes 5. 1 mm, and the approximate weight of diamonds can be known by measurement. You can also estimate the price of diamond ring.
