In Between Diamond Weights – Getting the Most for your Budget

We will often look at plain and simple advice on how you can gain the largest, and best diamond for your own particular budget. There are many ideas on how to achieve this, but unfortunately many of these ideas rarely make it into the public domain unless a part of verbal or written advice such as this. We never aim to sell a particular diamond, but are pleased when we can guide a client to what works best for themselves. Part of our service is ensuring a client receives the most that their budget can provide. We have decided in today’s blog to provide some ideas that will literally save a great deal of money, or enable a person to afford a little more than they had perhaps planned for. Choosing in between diamond weights can dramatically reduce the cost of any diamond ring design, with very little visual difference.

Carat Weight – Small Size Difference / Big Cost Difference

We have already seen that carat weight and diamond size have a close relationship. Diamonds are priced according to brackets of carat weights. This means that a diamond that oversteps a particular weight, by a miniscule difference, will leap significantly in price by comparison. Look at the list below and see what we mean. You will see that in between diamond weights can offer some spectacular savings to the person buying an engagement ring.

Size Brackets – Sizes in red represent more affordable sizes.

  • 0.30 – 0.39cts
  • 0.40 – 0.44cts – close to a half carat size but significantly less cost
  • 0.45 – 0.49cts – provides the show of a half carat but at less cost
  • 0.50 – 0.59cts
  • 0.60 – 0.69cts
  • 0.70 – 0.74cts – above this size usually results in paying a premium for a full 75pts
  • 0.75 – 0.79cts – more expensive than slightly lesser weights (little impact on size)
  • 0.80 – 0.89cts
  • 0.90 – 0.99cts – a popular alternative at less cost than the full 1.00ct stone

The actual millimetre size of a diamond will rarely make such a great difference  that you will notice the slight drop in carat weight. The cost can make quite an enormous difference to many people. Below we have included a classic example of two diamonds that are physically almost identical in size, colour, clarity etc. You will no doubt notice that the mm. size will have little impact on the overall appearance of the stone. The ring setting itself into which the diamond fits will be identical in size.

Example based on our classic Tiffany style four claw round solitaire – R1D001

0.50cts. Round Brilliant Cut. D VS1 GIA certified. Very Good Cut. 5mm diameter. (Platinum setting)

£2524.00  (at time of publishing this post) 5mm diameter

0.47cts. Round Brilliant Cut. D VS1 GIA certified. Very Good Cut. 4.8mm diameter. (Platinum setting)

£1873.12 (at time of publishing this post) 4.8/4.9mm diameter

Please note that whilst the website shows (by way of limiting the amount of prices) specific carat weights increments, we can supply any such in between diamond weights by request if we are contacted. This is particularly relevant for round brilliant cut diamonds that are more readily available across varying specifications than less widely available fancy shapes. Both Rounds and Princess cuts are popular shapes and are, as a result, more plentiful by way of available carat weight options. Less popular fancy shapes take a little more work in sourcing, but challenges are always welcomed.
