Frequently asked questions

There are so many variables that influence the price of a ring.
In short, the main factors are:

  • The 4C’s- extremely important that you educate yourself and discuss with your consultant in depth!
  • The quality, authenticity and ‘trust’ factor of the Certification (very important)
  • The metal you choose
  • Fluorescence

The truth is a ring can be manufactured for a countless variety of budgets. Depending on the colour, the clarity, cut and the size (carat) of your diamond – see 4C’s  here.

In addition to the 4C’s, a very important and often overlooked factor is the Certification. At Grace Diamonds we predominantly opt for either GIA or EGL stones.

The ring can also be made from platinum or gold (various karats ranging from 9kt to 18kt) which also affect the price.

Other often ‘hidden’ factors to take into consideration would be the Fluorescence of a stone. If you are not sure about this ask us to tell you more! This could be the difference in price you’re looking in terms of your budget, but if you are not forewarned you might be very disillusioned when you eventually get the ring and it has a ‘milky’ look to it or it shines bright purple under a UV light on a night out!!

All you have to do is decide on the amount you’re happy to spend on your dream ring and we will find you the biggest sparkliest diamond for your money.

The Inside Diameter (GREEN arrow) of a current, well fitting ring can be measured with a ruler and is a means of measuring ring size. Make sure to use the centre area of the ring as indicated above
