To some, size matters, and whilst we’d usually encourage you to prioritise the cut and beauty of your diamond, there are a number of ways you can ensure you find the biggest (and still, the best quality) diamond for your budget.

Read on as Queensmith’s top gemmologists share their secrets for finding the biggest and best diamonds in Hatton Garden for each individual’s budgets. Diamonds come in a variety of shapes, sizes and qualities - let us guide you to finding the best diamonds for your preferences and personal budget.

Aside from our usual advice to familiarise yourself with the 4Cs when choosing your diamond, here’s a roundup of our 8 savviest tips for finding the best diamond.

1. Browse & Buy Diamonds In Hatton Garden

Hatton Garden is the heart of the UK’s jewellery scene - meaning we’re spoilt for choice when it comes to finding the best diamonds for you. Whilst searching through diamonds for the perfect stone is no mean feat, there is no better place to search than the UK’s diamond hub - where you’ll find the best range and highest quality diamonds. You’ll need to find a gemmologist to help you navigate the diamonds on offer in Hatton Garden - but fear not, our consultants are highly trained, knowledgeable (and super friendly) gemmologists. Get in touch to meet with a gemmologist and view diamonds at our Hatton Garden jewellers, at a time that suits you.

2. ‘Under’ & ‘Oversized’ Diamonds

Carat weight largely drives diamond price

Finding a diamond in Hatton Garden, or even in the world’s global supply, that is ‘oversized’ or ‘undersized’ is not exactly easy, so manage your expectations - but know that if you find one it’ll be a great purchase. What does it mean? Diamonds are priced to the rounded decimal - the value increments increase significantly with each rounded decimal (whether that’s 0.50ct, 1.00ct or 1.50ct, and so on). An example of an ‘oversized’ diamond would be 1.04ct which, technically is larger than 1ct, but would carry a price tag closer to a 1ct stone. An ‘undersized’, for example 0.97ct, would cost significantly less than 1ct despite a very slight visual difference.

3. Choose Diamond Shapes That Appear Bigger

Oval diamonds appear larger than many other shapes of the same carat weight

Round brilliant diamonds are the most classic, popular and sparkly of diamond shapes. However, they don’t always appear the largest when compared to fancy diamond shapes of the same carat weight. Another benefit of fancy shapes is that they can be a little cheaper than rounds (carat for carat) as less diamond is wasted during the cutting process. Choose a diamond that’s elongated in shape, such as an oval, pear, marquise or rectangular radiant cut diamond.

4. Consider Brilliant Cut Diamonds

Brilliant diamonds, such as rounds, emit intense sparkle

A ‘brilliant’ cut essentially equates to a super sparkly diamond, particularly when the diamond cut grade is ‘excellent’ or at least ‘very good’. Brilliant cut diamonds are faceted to optimise light return within the stone (as opposed to ‘step’ cuts, which showcase the clarity of the diamond). The more sparkle, the larger the diamond looks! View diamonds like rounds, ovals, cushions and radiants to see the majesty of brilliant cuts.

5. Meet With Hatton Garden’s Diamond Experts

Queensmith's consultants are qualified gemmology experts

No one knows diamonds better than a trained gemmologist. Not all jewellers use in-house gemmologists to source their diamonds, so it’s important you find a jeweller that really knows what they’re selling. At Queensmith, our gemmologist consultants are passionate and dedicated to sourcing the best diamonds for each individual client and their budget. If you feel size is an important factor to maximise, let your gemmologist know. They’ll use their intricate knowledge to find the perfect combination of the 4Cs to find the best diamonds for you.

6. Lower Diamond Clarity And Colour Grades

Lower the clarity and colour of your diamond search to reduce the cost

Finding the perfect diamond for you is a balancing act between each of the 4Cs. Typically, the cut’ is the most important to consider - anything less than an ‘excellent’ or ‘very good’ can appear smaller than ideal for the carat weight, or larger but lacking lustre and sparkle. Instead of compromising on cut, lower the clarity and colour grades to boost the size of your diamond. Ideally, choose a colour grade above F and clarity grade above SI1, and instead put your money towards an excellent cut and optimal carat size.

In Hatton Garden, diamonds are sometimes sold without decent consideration of these points, so choose a jewellers with the ability to explain why each diamond will or won’t be a great purchase, in explicit detail. At Queensmith, we’ll always explain each diamond’s characteristics in depth, with the impartial aid of its GIA certification (or IGI for lab diamonds).

7. Consider A Coloured Gemstone

You may be certain that a diamond is the stone for your engagement ring, but if you’re not a total traditionalist, you might want to consider a coloured gemstone. Carat for carat, sapphires, rubies and emeralds tend to cost less than diamonds, meaning the size of the gemstone you choose will likely be larger than a diamond of the equivalent cost. The most popular alternative to diamonds, sapphire engagement rings make beautiful romantic gestures with unique charm and colourful character.

8. Choose A Design To Accentuate Your Diamond

There are certain ways to maximise the look of your diamond, and your ring as a whole, without having to splurge on a diamond beyond your budget. The first solution: choose a halo engagement ring. With halo engagement rings, you can sacrifice some carat weight on the centre diamond and achieve a larger look with melee diamonds set around the centre stone - multiple diamonds of the same total carat weight as one diamond will be less expensive.

Alternatively, choosing a super simple design means saving on the cost of extra metal work: browse solitaire engagement rings for a simple engagement ring and put the rest of your budget towards one diamond.
