Now you can buy a loose diamond online in lower clarity grade in a peace of mind.

The platform is really user-friendly. You can easily and quickly refine the multiple searches by adjusting the bars. Shortlisted diamonds can be compared side by side too.

I’ve tried to ask several questions via email and I am amazed that they could replied in 24 hours in spite of weekend.

Although it is guaranteed that the price of diamonds from JA lower than retails shop outside, from diamond price comparison chart, JA may not be the cheapest among all online stores due to the heat competitions. However, it is the unbeatable online stores as you can make good use of the unique 3D view and choose the best value diamond (best value in decent price) smartly.
