Best Time of Year to Buy Diamond Jewellery: A Practical Buying Guide

Understanding the best time of year to buy diamond jewellery can help you make a smarter purchase.

While diamonds are valuable year-round, certain seasons and sale periods can offer better opportunities to compare prices, access promotions and secure the piece you want.

If you’re planning to buy an engagement ring, loose diamond or special jewellery piece, knowing when retailers typically run promotions can help you decide when to purchase.

Are diamonds more affordable at certain times of year?

Many people ask what time of year diamonds are affordable. Unlike electronics or fashion, diamond prices do not fluctuate dramatically throughout the year because they are based primarily on supply, demand and the quality of the stone.

However, jewellery retailers often run seasonal promotions, which means the best time of year to buy diamonds often aligns with retail sale periods rather than changes in diamond market prices.

Key sale periods in Australia

In Australia, there are several retail events can offer favourable opportunities to buy jewellery:

End of Financial Year (EOFY)

EOFY sales in June are one of the most common times to see jewellery promotions. Many retailers reduce prices or offer incentives before the new financial year begins.

For buyers researching what time of year diamonds go on sale, EOFY is often one of the strongest opportunities to compare offers.

Black Friday and Cyber Monday sales

Late November sales have become increasingly popular. Many jewellery retailers offer online discounts or special promotions during this period.

For buyers exploring the best time of year to buy diamond jewellery, Black Friday can provide a chance to secure a piece before the Christmas rush.

Christmas and Valentine’s Day promotions

Retailers often introduce promotions leading into major gifting seasons such as Christmas or Valentine’s Day.

While demand is high during these periods, some jewellers run early seasonal promotions that allow buyers to secure jewellery ahead of peak gifting dates.

Best time to buy engagement rings

If you’re planning a proposal, timing can matter. Many couples begin engagement ring shopping months before the proposal itself.

The best time to buy often depends on how long you need for:

  • choosing a diamond
  • designing a custom ring or purchasing a ready-made one
  • resizing or adjustments

If you’re planning a bespoke design, it’s usually best to start several weeks in advance so you have time to compare stones and settings.

Best time of year to buy loose diamonds

Regarding the best time to buy loose diamonds, the strategy is slightly different.

Loose diamond prices depend mostly on the quality of the stone rather than seasonal discounts. The best approach is to compare certified stones carefully and purchase when you find the right balance of cut, colour, clarity and carat.

You can explore available stones through our loose diamonds collection and compare options based on the 4Cs.

For those considering alternatives, lab-grown diamonds can provide a larger stone for the same budget.

Timing your purchase strategically

Beyond seasonal sales, timing can also depend on personal milestones.

Many buyers purchase diamond jewellery for:

  • engagements
  • anniversaries
  • birthdays
  • personal milestones
  • personal style

Rather than waiting for discounts alone, the best approach is to prioritise quality and long-term value.

Our guides on how to build a jewellery collection and how to invest in diamonds can help you understand how jewellery fits into a broader long-term investment or collection strategy.

Buy when the right diamond appears

While retail sales can create opportunities, the truth is that the best time of year to buy diamond jewellery is often when you find the right stone.

High-quality diamonds are unique. Waiting for a specific sale may mean missing a stone that perfectly matches your preferences.

The smartest approach is to monitor the market, compare certified diamonds carefully and purchase when the right combination of quality, price and design appears.
