When considering Hatton Garden engagement rings, setting a budget is a personal decision that should feel entirely your own. There is no set formula or expectation for how much to spend. What matters most is finding a balance that feels comfortable and genuine to you. An engagement ring is a meaningful symbol of commitment, and its value lies in what it represents, not simply its price.
The cost of an engagement ring can vary depending on many factors, including the diamond’s quality, the craftsmanship of the ring, and the style you choose. Understanding these details can help you make a confident and well-informed decision.
In this guide, we’ll help you consider how to set a budget that feels comfortable and discover a ring that perfectly reflects your love.

Why the “Rule of Thumb” Shouldn’t Guide Your Engagement Ring Budget
When it comes to planning an engagement ring purchase, many people encounter what is known as the “rule of thumb”. This long-standing notion suggests that an engagement ring should cost around two to three months’ salary. Rather than being a traditional custom, it originated in the 1930s as part of a marketing campaign created to boost diamond sales during a time of economic uncertainty, presenting the idea of a set spending rule as a gesture of commitment.
Although the idea has endured for generations, it no longer feels relevant to modern life. Everyone’s circumstances and priorities differ, and a single rule cannot account for the variety of today’s lifestyles and relationships. What may feel right for one couple could feel completely unrealistic for another.
Ultimately, an engagement ring should embody thoughtfulness and sincerity, not conformity to an outdated rule. Some couples may spend less, others around the suggested amount, and some considerably more. What matters is that the choice feels right for them.
Factors That Affect the Cost of an Engagement Ring
The price of an engagement ring can vary considerably depending on several factors, each contributing to its overall appearance, quality, and craftsmanship. Understanding these elements can help you make confident choices that reflect both your taste and budget.
A diamond’s value is determined by four key characteristics: colour, clarity, cut, and carat weight.
- Colour refers to how white or colourless the diamond appears. The closer it is to colourless, the rarer and more valuable it becomes.
- Clarity measures the presence of natural inclusions within the diamond and blemishes on its surface. Fewer of these characteristics generally result in a purer diamond.
- Cut influences how well the diamond reflects light, directly affecting its sparkle and overall beauty.
- Carat weight indicates the diamond’s size, with larger stones typically commanding higher prices.
Ring Setting
The setting plays an important role in the final cost of an engagement ring. The choice of metal, such as platinum, yellow gold, rose gold, or white gold, affects both the price and overall aesthetic. More intricate settings, including those with diamond shoulders or halo arrangements, require additional craftsmanship and may therefore cost more than classic solitaire designs.
Brand and Design
Well-known brands and large international chains often carry higher prices, reflecting their overheads and marketing costs rather than necessarily superior quality. By choosing a reputable independent or family-run jeweller, you can often enjoy exceptional craftsmanship, personal service, and better value for money. Bespoke designs add a unique and personal touch, though they typically come at a higher cost, so this should be considered when setting your budget.

Setting a Realistic Budget for Your Engagement Ring
A helpful first step can be to spend some time window shopping in Hatton Garden. There’s no need to buy anything at this stage; simply explore different jewellers, browse the displays, and get a feel for what catches your eye. Seeing a range of designs and price points in person helps build a clearer understanding of what influences cost and what you might reasonably expect within your preferred price range. This can be done with or without your partner, depending on your preferences.
Some prefer the element of surprise, selecting the ring themselves while working within a general budget. Others choose to select the ring together, where an open conversation about how much to spend often happens naturally. Both approaches are equally thoughtful, and what feels right will depend entirely on the couple.
The key is to set a budget that allows you to choose a ring you feel genuinely excited about and that reflects the significance of the moment without overextending financially.
