PT950 is about 570 grams, and the ring holder is about 2.4 grams, so counting the process, it is about 1500.
Diamond 16.5 points, based on the size and decorative significance, has no preservation value; The color I-J is not ideal, and the diamond color is a little yellow; The definition VVS is good, with a very slight defect level; If the cutting is not bad, the personal evaluation is within 1500.
So my personal total valuation is around 3000. The landlord's offer is still within a reasonable range.
