Is 10 ct diamond suitable for the engagement ring?

10 carat diamonds are a stunning and luxurious choice for an engagement ring — the huge size of the diamond is ideal for creating an engagement ring that truly makes a statement. That being said, the scale of a 10 ct diamond will require wearers to be more careful to avoid knocking it or getting it caught on fabric, which can cause damage to the ring.

Which cut seems largest for a 10 carat diamond?

Round diamond rings are the most popular option for many people, but an oval shape would save you over 30% of the total cost. An Asscher diamond can help you save some 40% on the total cost. Round brilliant-cut diamonds are the most expensive per carat because they require the removal of the most amount of material from the rough.

What is the average price for a 10 carat diamond?

The average price of a 10 carat diamond is $435,611, but 10 carat diamonds can cost anywhere from $185,500 to $1,306,298 depending on the diamond's shape, colour, clarity, and other factors.

Should I get insurance for a 10 carat diamond ring?

Yes, insuring a 10-carat diamond ring is highly recommended. Such a valuable piece of jewellery can be a significant financial investment, and insurance provides peace of mind against potential risks like theft, loss, or damage. Insurance will help cover the cost of repairs or replacement, ensuring you’re protected should the unexpected happen.

How will a 10 carat diamond look like on a hand?

A 10-carat round diamond ring is exceptionally eye-catching, with its size covering approximately 85.3% of the finger’s width.

10 carat diamond

A 10 carat diamond is a truly statement stone — and understanding what goes into choosing one will help you get the best value for your investment.

A round cut 10 carat diamond measures approximately 14×14×8.44mm, though it's important to note that carat refers to weight, not size. Different shapes carry their carat weight differently — a princess cut 10 carat diamond ring, for example, can appear larger than a round cut of the same weight due to its longer diagonal span.

When it comes to settings, balance is key. A thin band creates a striking "floating" effect that puts the 10ct diamond ring centre stage, while a wider band offers a more grounded, secure feel. Certain settings — from a classic solitaire to a dramatic double halo — can also enhance the stone's visual presence. The GS Diamonds team is on hand to guide you through the options and help you design the perfect ring.

10 carat diamond prices at GS Diamonds start from around A$366,944, with a realistic range of A$366,944 to A$1,170,903 depending on the combination of Cut, Colour, Clarity, and Carat. Finding the right balance across these four factors is the best way to maximise beauty without unnecessarily inflating the 10 carat diamond price.

Every loose diamond in our inventory comes with an original GIA Grading Certificate — the most trusted report in the industry — and most are laser inscribed with a unique identification number for complete peace of mind.

GS Diamonds offers free insured shipping across Australia and New Zealand, with stores in Sydney, Brisbane, Melbourne and Perth. We accept a wide range of payment methods in-store and online, and all fully-paid purchases up to $15,000 (excl. GST) are covered by a 30-day money-back guarantee.
