Explore the 1.5ct Lab Grown Diamond Ring Collection

A 1.5ct lab grown diamond ring gives you a balanced mix of size, shape and design. It’s large enough to carry presence and sparkle, but not so big that it feels oversized. Solitaire Jewellery sources certified stones that meet high grading standards in clarity, colour and cut. The diamonds are certified and graded for cut, clarity and colour. Each ring is carefully inspected before it’s made available online or in-store.

The collection covers a wide range of styles, with options across solitaire settings, halos, and multi-stone designs. To see what’s available now, browse our full selection of lab grown diamond rings, or head to the lab grown diamonds category for additional size and cut options.

Refined Proportions with a Strong Visual Impact

The 1.5 carat size is one of the most versatile. On a round cut, this weight gives you a diameter of about 7.4mm, which is enough to offer strong finger coverage without looking bulky. Elongated shapes like oval or emerald cuts can appear even larger, depending on the setting.

This makes the 1.5ct size especially popular in our engagement rings range, where balance and proportion matter. The size also works well in both classic and modern styles, giving you plenty of flexibility with metals and band widths.

Popular Shapes and Metal Options

You’ll find 1.5ct lab grown diamonds in all major cuts, including round, oval, emerald, pear and radiant. Metal options include yellow gold, white gold, rose gold and platinum. Whether you prefer something minimal or a setting with more detail, we offer designs to suit both everyday wear and more formal styling.

If you're shopping beyond engagement pieces, you can explore our broader rings collection. This includes updated takes on traditional diamond rings and personal pieces like signet rings.

Want to stack or layer your look? Our stackable rings work well with a 1.5ct centrepiece. For a bolder approach, our statement rings provide more visual contrast and styling range.

Certified Stones with Consistent Quality

Each 1.5ct lab grown diamond ring from Solitaire Jewellery comes with IGI or GIA certification. These stones are created under carefully controlled conditions to deliver consistent results in colour, clarity and brilliance. Certification provides clear documentation for grading and ensures that clients can compare options confidently.

We maintain live availability across all lab grown sizes so you can view the most current selection by shape, setting and finish.

Finished Locally, Built to Last

All Solitaire Jewellery pieces are reviewed in-house before shipping. You can request resizing, setting changes or updates to the band metal. Every order comes with full certification, insured packaging and tracked delivery.
