How engagement ring spending compares to market averages

According to recent industry surveys, average consumer spending on engagement rings provides a practical benchmark, even when your aim is an investment-grade piece. For example, The Knot’s national survey reflects typical purchasing behaviour rather than the premium segment focused on long-term value. These averages help you see how mainstream choices differ from investment-oriented ones.

Investment-grade rings generally cost more than the national mean. The reasons are straightforward: larger carat weights, superior cut proportions that maximise brilliance, and the use of higher-purity metals such as 18Kt gold or platinum increase both material cost and lasting value. Mainstream purchases often prioritise immediate look within a budget; buyers aiming for investment value prioritise rarity and certified grading  -  larger stones, excellent to ideal cuts, higher colour grades and cleaner clarities  -  which command premiums in market data.

Interpreting averages for your decision

Averages are a starting point, not a rule. Use survey figures to understand how most people allocate their budget, then adapt those benchmarks to your goals. If resale potential or long-term value is your priority, expect to spend above the average and focus on the attributes that influence secondary-market desirability: carat size, cut quality and certified reports. If symbolic value and immediate visual impact matter more, you can achieve a striking result closer to the mean by prioritising cut and setting over maximum carat weight.

Putting data into practice

Treat published averages as reference points when you talk with a trusted advisor. When comparing quotes, ask to see certified reports and request a clear explanation of how each attribute affects long-term value. That way, survey numbers help frame a sensible budget range without dictating the specific investment choices that will determine the ring’s future worth.

Advantages of buying as an investment

The advantages of buying as an investment are multiple. From the value of the piece that increases over time, to the resale opportunities, buying an investment engagement ring is a good alternative that doesn’t necessarily cost more than a regular ring, it just involves making smarter choices.

In investment jewellery we look at 2 main points, the choice of the metal, either gold or platinum; but the main factor is of course the the diamond(s). Ideally the ring needs to be 18Kt gold and not lower, because a lower caratage means a less pure alloy with a smaller quantity of gold so it won’t have the same value as an investment.

Same goes with platinum, it is a precious metal that is actually very rare and therefore expensive and considered a great investment asset.

But the most important part is of course the diamond. It is advised to have a nice white colour without visible impurities. The diamond needs to have some rarity, including a size of 1cts and larger and of exceptional colour such as D, E, F or G and exceptional clarity such as Internally Flawless up to VS2. The cut grade also needs to be at least Very Good, so that the diamond has the best proportions and the ideal fire and brilliance needed.

Budgeting and saving strategies for buying an engagement ring

Start with a clear plan. Decide on a total budget range that feels comfortable, then rank the attributes that matter most  -  for investment rings the usual priority order is carat, cut, colour and clarity. When appearance is the main concern, prioritise cut quality. For long-term value, favour larger carat weight combined with an excellent cut and certified grading.

Practical saving approaches

• Short-term: focus savings on attributes with the largest visible impact, typically cut and setting, while staying within BAUNAT’s recommended colour and clarity thresholds (colour H or better, clarity SI1 or better). Avoid sacrificing cut for size, since brilliance depends on proportion.
• Medium-term: increase the carat target while keeping cut at Very Good or higher and maintaining the recommended metal choice, such as 18Kt gold or platinum.
• Long-term: plan for a higher-tier stone and bespoke setting, saving progressively toward a certified investment-grade diamond.

Avoid taking on unnecessary debt. Financing is an option, but prioritising savings reduces financial strain and keeps the purchase aligned with its investment rationale.

Trade-off examples

If carat is the priority, consider a slightly lower colour or clarity within brand-allowed specs to optimise size without noticeably affecting face-up appearance. Conversely, if you want maximum brilliance per amount spent, invest more in cut quality and a well-proportioned setting rather than pushing for a larger but poorly cut stone.

Immediate action items

• Set a target carat range and acceptable colour/clarity thresholds (colour H+ and clarity SI1+).
• Decide on metal preference early (18Kt gold or platinum).
• Open a dedicated savings account or savings pot for the purchase.
• Schedule an appointment with a BAUNAT expert to align your budget with investment-grade options.

These steps help you save with purpose and make choices that balance immediate beauty with long-term value.

Why this would be a good option for you?

For all these reasons, it would be a wise choice to select an engagement ring that will not only be beautiful and symbolise your love and the new adventure, but it will also be an investment and increase value over the years.

It is true that it is not easy to know what to look for, that is why it is recommended to do some research online and to contact a professional to guide you in the process in order to ensure you pursue the right investment project.

BAUNAT is the leader on the market for investment diamonds, but also in high-end designer jewellery, so don’t hesitate to contact one of BAUNAT’s experts to guide you in the process of choosing your ideal engagement ring that could also be considered a long term investment.

Where to buy: online, local, or vintage/estate

Each purchasing channel has distinct advantages for buyers seeking investment-grade engagement rings. Online retailers often offer clearer price transparency and a wider selection, including detailed grading reports and high-resolution images that make comparison easier. Reputable online specialists provide certified documentation and clear return terms, which are essential when judging investment potential. The convenience of remote shopping should be balanced with careful verification of certificates and seller reputation.

Local jewellery stores let you inspect a diamond face-up under familiar lighting. That tactile experience can be decisive, especially when assessing cut and brilliance. Independent jewellers and established boutiques may offer personalised service, bespoke setting options and local provenance records that can help with future resale. For investment purchases, ensure the retailer supplies full certification and a documented history of the stone.

Vintage and estate rings can appeal to buyers who value rarity and character. Provenance and condition matter; when considering an estate piece, request grading documentation or a recent re-assessment to confirm the diamond’s attributes. Vintage settings sometimes need restoration or resetting into a modern mount to improve value and wearability, so factor a professional appraisal into your decision.
