Whether you're marking a moment or starting a new chapter, our one-carat diamonds provide a lasting expression of elegance and intention.

What Are Lab Grown Diamonds?

Lab grown diamonds are real diamonds, cultivated under conditions that replicate natural formation. They possess the same chemical, physical, and optical properties as mined diamonds. The only difference is their origin.

Each of our 1 carat lab grown diamonds is created in a controlled setting, free from the destructive practices of traditional mining. They’re inspected, graded, and certified by leading gemological institutions, ensuring you receive a stone that’s both beautiful and authentic.

Why Choose a 1 Carat Diamond?

The one-carat weight is a classic for a reason. It offers the perfect balance of visual impact and wearability. For many, 1 carat lab grown diamonds are the ideal size: large enough to command attention, yet timeless in proportion.

Benefits of choosing this carat weight include:

• Versatile size for rings, pendants, and earrings

• Excellent brilliance and fire in the most popular cuts

• Ideal for those seeking beauty, quality, and value

• A meaningful gift or statement piece that’s easy to wear every day

With lab-created options, you can enjoy a one-carat diamond that meets the highest standards—ethically and financially.

Shapes That Match Your Style

The shape of a diamond greatly influences its overall aesthetic. Our 1 carat lab grown diamond collection includes a wide selection of cuts, allowing you to choose a stone that suits your personality or occasion.

Available shapes include:

• Round Brilliant – timeless and most light-reflective

• Princess – modern, angular brilliance

• Oval – elongated elegance with classic appeal

• Cushion – soft corners with vintage charm

• Emerald – sleek lines and subtle sparkle

• Pear – a blend of round and marquise with a unique flair

Every diamond is precision-cut to enhance brilliance and maximize its beauty.

Certified Quality You Can Trust

Every 1 carat lab grown diamond in our collection is graded by top laboratories like GIA, IGI, or GCAL. These certifications provide a complete report on the 4Cs—cut, color, clarity, and carat—and confirm the diamond's lab-grown origin.

With your diamond, you’ll receive:

• A certificate verifying the 4Cs

• Laser inscription for identification

• Documentation suitable for insurance or appraisals

You can shop confidently, knowing exactly what you're buying.

A Smarter, More Ethical Choice

Opting for 1 carat lab grown diamonds is a conscious decision. Not only are these diamonds more affordable, but they’re also produced without the ethical issues or environmental damage associated with mining.

Key sustainability benefits:

• No habitat destruction or water pollution

• Conflict-free sourcing and responsible labor practices

• Reduced carbon emissions and energy use

• Transparent production with full traceability

You don’t have to sacrifice luxury for values—instead, you get both.
