Have a large-carat lab-grown diamond engagement ring design to develop?

Brrin Jewelry supports custom engagement ring manufacturing for jewelry brands, designers, wholesalers and trade clients, with lab-grown diamond sourcing, CAD development, setting and small-batch production.

Large Carat Lab-Grown Diamond Sourcing

We can source large-carat lab-grown diamonds according to your project requirements, including:

  • Oval

  • Emerald

  • Pear

  • Radiant

  • Cushion

  • Round

  • Other fancy shapes

Large-carat oval and emerald-cut lab-grown diamonds reviewed for custom engagement ring projects.

Diamond selection can be based on carat weight, dimensions, color, clarity, certification and overall appearance.

IGI-certified lab-grown diamonds can also be sourced when required.

Custom Engagement Ring Development

Large-carat engagement rings often require more attention to setting proportions, stone dimensions and structural support.

We can develop custom settings based on:

  • Confirmed center stone dimensions

  • Reference images

  • CAD files

  • Technical drawings

  • Existing ring concepts

  • Client-supplied designs

Our CAD team can help adjust the basket, prong position, band width and setting height before production.

The setting structure is reviewed according to the center stone size, shape and finished ring requirements.
