Eddie is relatively better. The brand is slightly stronger, and the prices of the two brands are relatively moderate.

As for the P750 you mentioned, it should be AU750, which means 18K gold inlay.

P950 should also be PT950 (that is, platinum).

Things are different. . 18K is gold with a gold content of 750%. PT950 is platinum with a gold content of 950%. The latter is more expensive.

General professional diamond ring should be 18K gold, because it has high hardness, good gloss and moderate price. Compared with platinum, you can choose a ring with a larger diamond at the same price. The ring is not easy to deform, and the inlay is firm and stable.

If PT950 is inlaid with platinum, it feels better, because platinum symbolizes purity, while diamond is a single carbon element, which also symbolizes uniqueness and purity. The combination of two substances is synonymous with love. . . Unique. . . Purity. . . Eternity .

However, it is easy to lose the luster of the platinum ring after wearing it for a period of time, and the ring will be deformed after wearing it for a long time. So it is not suitable for you to work often, because once the ring is scratched, the diamond may fall off.

Generally, Chow Tai Fook and Lukfook in Hong Kong are inlaid with 18K gold. So it's not that 18K gold is badly inlaid, but what it is used for. Some people will say that K-gold will change color, which is inevitable and will definitely change color. But don't worry, K-gold jewelry can be gilded, and the cost of gilding is not high. As long as it is around 20 yuan once, it will be as good as new after gilding. It makes no difference.

The next step is the grade and size of the diamond.

The choice of diamonds needs to be measured by 4C. Don't just listen to VVS introduced by salesmen. This VVS is only the level of clarity, but also depends on its color, which is the most intuitive to the naked eye. Nice color. (F-G -I-J) The brighter and whiter it looks, there are 4C boards on the counter. You can listen carefully to what he introduced. Then there is cutting. At present, the mainstream cutting is eight hearts and eight arrows. The refraction surfaces of the eight arrows can be seen through the cutting mirror. Then the size of the diamond. The bigger the diamond, the higher the price. . . The two brands you mentioned are ultra-low discount brands. Generally, you can get about 30% discount, and if you buy them internally, you can get 7.5% discount. . .

You said to surprise your girlfriend in advance, so you need to find out in advance what size ring he will wear, because diamond rings are all dead, that is, there are fixed numbers, and the numbers can only be increased or decreased by three. The diamond ring can be changed at most twice in a lifetime, and the number of ring changes increases the setting firmness of the image diamond. If he is not very fat, his height is about 165CM, and his weight is between110/20, then his hand index should be 12- 13, and then you can calculate his hand index according to my data. If not, you can choose the size of 12 and change it from 15 to 10. Also, the setting method of diamonds is related to the change of rings. Some styles can not be changed in three sizes, such as sleeve type and sleeve type. . . . .

Therefore, I recommend choosing K gold with diamonds, and the brand is more inclined to Adil. My jewelry salesman, professional advice. For reference only.
