Discover 2ct Lab Grown Diamonds

Solitaire Jewellery’s 2ct lab grown diamond range offers a balance of size, quality and comfort. The 2 carat mark gives noticeable presence without overwhelming the hand, making it a solid choice for engagement rings or a timeless self-purchase.

This collection brings together certified lab grown diamonds with modern styling. Each ring is made with attention to cut, colour and finish. Our local team reviews every piece before it’s sent out, so you can trust that what you see is what you get.

Our Collection of 2ct Lab Grown Diamond Collection

The 2ct lab grown diamond is one of the most requested carat sizes in fine jewellery. It’s large enough to offer impact while staying comfortable for daily wear. This makes it a practical option for people who want a standout ring without pushing into heavier, high-maintenance territory.

You’ll find 2ct options across solitaire settings, halos and custom styles. Explore our full range of lab grown diamond rings to compare shapes and metals, or start with the broader lab grown diamonds category for a full overview.

A Practical Size with Lasting Splendour

The 2 carat range gives excellent finger coverage without losing balance on the hand. Round cuts measure about 8.1mm in diameter, while elongated shapes like oval or pear can give an even larger face-up appearance. This size carries enough visual weight for special pieces without being difficult to wear.

It’s a popular option in engagement rings, especially for those who want something noticeable but still easy to pair with a wedding band.

Settings and Finishes That Work

We offer 2ct lab grown diamonds in all four gold colours as well as platinum. Settings include solitaire, halo and three-stone, all designed to hold the stone securely and bring out the cut’s shape and brightness.

If you’re building a piece that reflects your style, you can browse our full rings collection. You’ll also find related pieces in our diamond rings section, which includes classic and contemporary styles.

Looking to add dimension or wearability? You can layer with stackable rings or go bold with statement rings. The 2ct stone also pairs well with modern signet rings for a custom finish.

Certified Stones You Can Trust

All 2ct lab grown diamonds at Solitaire Jewellery come with GIA or IGI certification. Each stone is lab grown under consistent conditions that allow for traceability in colour, cut and clarity. The certification confirms all key grading details, so buyers can make clear comparisons across shapes and sizes.

We keep our 2 carat listings updated in real time, with full product information available on each ring. If you’re browsing for a gift or planning a proposal, this carat size gives you flexibility without having to compromise on quality.

Designed and Finished in Australia

All Solitaire Jewellery rings are inspected locally before dispatch. Whether you’re buying online or booking a consultation, we focus on making the process clear and efficient. You can customise your 2ct lab grown diamond ring by changing metals, adjusting ring size or selecting a new setting from the same diamond category.

Each order includes secure packaging, tracking and full certification. That way, you can be sure the ring arrives exactly as described.
