The price of a diamond ring varies widely depending on factors like the diamond’s size, quality (cut, color, clarity, and carat), the type of diamond (natural, lab-grown, or clarity-enhanced), the setting, and the choice of metal[4].
On average in 2025, a diamond engagement ring in the United States typically ranges from $5,000 to $6,000[1], while in the UK, the average purchase price is around £2,000[13].
For more specific pricing by diamond type and size:
- 1 carat natural diamond ring: $4,000–$5,300[5]
- 1 carat clarity-enhanced diamond ring: ~$3,500[5]
- 1 carat lab-grown diamond ring: ~$1,000[5]
- 2 carat natural diamond ring: ~$15,000[5]
- 2 carat lab-grown diamond ring: ~$3,000[5]
Lab-grown diamonds are typically 80–85% more affordable than natural diamonds, and clarity-enhanced diamonds offer 30–40% savings compared to untreated natural diamonds[5].
Other factors affect the final price, including:
- Ring style and design complexity — designs with halos or many side stones cost more[4]
- Metal choice — platinum is typically more expensive than gold (white, yellow, or rose)[4]
- Brand, location, and retailer — prices can vary by region and store[1]
Ultimately, how much to spend on a diamond ring is a personal decision that should take into account financial comfort, style preferences, and value considerations[4].
