D-0.03 1ct
0.07 carat in diameter
The back is the composition of diamonds. I forgot whether it was clarity or score.
You said you had a certificate. Only Chow Tai Fook has a certificate of approval for the jewelry I bought. Old brands such as Lao Fengxiang and Jade Jewelry also have no certificates, but they have formal invoices.
If you are really worried, you can check at the counter. But this price. Not really, because a gram of gold is 350.
Necklace 3, 4 grams, diamond 2, 3 thousand. It is probably fake!
But the heart is the most important thing.
