How to choose a 30 point diamond ring
1. Choose a reputable and reliable brand
Due to people's obsession and pursuit of diamond rings, there are various diamond ring brands of different sizes on the market. It is recommended that consumers choose well-known diamond ring brands when purchasing diamond rings, which have both quality assurance and after-sales and service guarantees.
2. Watch Diamond 4C Grade
The 4C of a diamond determines its quality, which is the most important component of the price of a diamond ring. The 4C standards for diamonds are weight, color, clarity, and cut. Here, it is recommended that newcomers who pursue cost-effectiveness can choose color H+clarity VS2+cut 3EX. If they pursue high quality, they can choose color D+clarity VVS2+cut 3EX.
3. Check the material of the ring holder
The mainstream diamond ring materials on the market are platinum and 18K gold, each with its own advantages and disadvantages, mainly determined by the buyer's preferences. Platinum has a natural pure white color that is not easy to fade and can better highlight the brilliance of diamonds, but its price is slightly higher. 18K gold has high hardness, fashionable and novel colors, and a lower price than platinum.
