The subject is that the white on the ring has fallen off
The diamond ring is 18K gold inlaid, 18K gold is yellow after the mold is out of the mold. After inlaid gemstone After falling off, it is yellow.
, but 18K gold is not easy to fall off. After a long time, there will be a small area of wear. The yellow is leaked out. It is almost impossible for the situation in the main photo of the subject.
So the subject is still necessary to identify it. There are many appraisal agencies in Shenzhen. The following three are the most authoritative for reference:
NGTC Shenzhen Inspection Center Shenzhen Futian Central District, Shennan Avenue, No. 2009, No. 2009, No. 2009 Investment Building Fourth Floor 0755-82912709
The quality supervision and inspection center of the National Gold and Silver Products Quality Supervision and Inspection Center Shenzhen Laboratory, Cuizhu Road, Honghuang, Honghu Pavilion B1202 Room 0755688667/0755624955
countries Jewelry Quality Supervision and Inspection Center, Shenzhen Luohu District, No. 71 Beli North Road, Luohu District, Shenzhen, Water Beiya wholesale Market 2 Floor area 0755-25633295
This does not need any appraisal agency. In fact, you already understand it yourself. Your question is very clever, the "masonry ring" instead of a diamond ring, the finishing touch!
You are obviously a crafts with ordinary materials. Didn't you see it? The fake drills around all fell, and the one who did not stuck in the middle had already dropped. Drop, no value.
