After you have optimised the 4 C’s between quality and size, there are a few more tips and tricks to optimising your value for money. Diamond pricing is based on demand, as most diamonds asked for are round brilliant these diamonds come at a premium. Along with the added demand for round brilliant diamonds these diamonds produce the most off cuts when they are being cut from a rough stone to a finished diamond, therefore increasing the cost.
