Please you should also take into account that women are simply fond of jewelry and it can be also something special for her. My DW was very excited when I presented her with this diamond ring pierrejewellery.nz/ She said I touched her very deeply with that gift. These guys will take upon themselves the delivery of their products worldwide by the way
There are two parts to buying a diamond ring. The diamond and the ring mount. As for the diamond, you should definitely buy one online. But make sure you buy from a reputed company and get a diamond which has been certified by a top notch lab. Go for GIA preferably. They are the best. You can read the certificate no on the girdle using a basic loop and this will ensure you don't get duped. Buying online ensures massive range and better prices. Unless you are buying a low quality stone like SI2 or below there is nothing to see and inspect. But if you are then you should get it inspected for eye clean. Stores cannot match the prices online unless they are conning you with a sub standard certificate. And it's unlikely that they will have enough inventory to show you a lot of actual pieces. They will have a few but buying from the lot is like buying directly from an airline and not comparing across airlines.
