I have been buying jewelry from this chain for more than 3 decades, and never got any issue, their making charge is much higher than any of the other stores as they employ so many people but very very reliable. When it comes to astrological gemstones or diamond, one can blindly trust them. They usually do not keep heated treated gemstones, but if they have, they will tell you while displaying, wont hide like other stores. They provide certificates form reliable gem testing labs. So I will always recommend PCC.
