Frequently Asked Questions

A: A 1 carat diamond ring price in Australia typically starts from around $7,000 and can reach $25,000 or more, depending on the diamondโ€™s cut, colour, clarity, and shape. For example, a 1 carat oval diamond ring or a 1 carat princess cut diamond ring may be priced differently, with ovals often giving you a little more surface area for the money. At DDS Diamond Design Studios, weโ€™ll show you actual stones and settings, so you can see how each factor influences the final price.

A: For most engagement rings in Australia, 1 carat is considered the โ€œgold standard.โ€ It has enough size to stand out, especially as a 1 carat solitaire diamond ring or a diamond 1 carat engagement ring, but is still comfortable for daily wear. Some clients prefer a little less for a delicate look, or go higher for a bold statementโ€”but 1 carat remains the most sought-after size for its balance and beauty.

A: Yes, a 1 carat diamond is a substantial stone and is often seen as the perfect size for both engagement and wedding rings. When set in a 1 carat diamond wedding ring or a 1 carat diamond solitaire ring, it has real presence on the hand, without feeling oversized. For many, itโ€™s the sweet spot between subtle and eye-catching.

A: Today, a 1 carat diamondโ€™s value depends on more than just weight. Cut, colour, clarity, and certification all play a part. At DDS, we see certified 1 carat stones ranging from $7,000 to $25,000 or more. For example, a high-clarity, colourless 1 carat diamond in a custom setting will sit at the top end, while a beautiful, slightly tinted or included diamond might fall lower in the range. We break down every detail so you know exactly where your investment goes.

A: Ovals, marquise, and pear-shaped diamonds offer the largest surface area for their carat weight. If you want a 1 carat diamond ring that looks as big as possible, a 1 carat oval diamond ring or a 1 carat oval diamond engagement ring will appear larger than a traditional round or princess cut. Our team can show you direct comparisons so you can see the difference in person.
