How Much to Spend?

Antiquated etiquette guides suggest spending two or three months' wages on an engagement ring, but this outdated idea carries little weight today. The advice is to spend what you can comfortably afford. If you're concerned about cost, lab-grown diamonds offer an indistinguishable alternative to mined stones at a fraction of the price.

Finding Their Ring Size

If your partner has a jewellery box full of rings, simply borrow one and show it to a jeweller to determine the size. Alternatively, inexpensive ring sizers are available online. For those who would notice a missing ring, tracing the inside of a ring onto paper can help. According to a Hatton Garden jeweller, the average ring size for women is M, so going with the crowd and ensuring resizing is possible later is a safe bet.

When to Buy the Ring?

The most popular time to propose in the UK is Christmas, with more couples getting engaged between Christmas Eve and New Year's Day than any other time. Holidays, anniversaries, and Valentine's Day are also popular. Whichever date you choose, order the ring a few months in advance to allow time for design, forging, and sizing.
