Lab-Grown Diamond Engagement Ring

Soft light catches the gentle curves of a cushion-cut diamond, its rounded corners and subtle facets inviting a quiet intimacy. This three-stone semi-set engagement ring in warm 18K rose gold offers a handcrafted foundation ready to cradle an 8 x 8 mm center stone of your choosing.

Each band is shaped and polished in our Williamsburg studio, where the artisan’s touch ensures a smooth comfort fit that sits low against the finger. The three-stone setting balances presence with wearability, designed to layer gracefully alongside wedding bands or stackable rings without catching.

Our lab-grown diamonds bring clarity and brilliance with a smaller environmental footprint, reflecting a commitment to ethical jewelry without compromise. The rose gold’s soft blush hue complements a range of skin tones, enhancing the cushion’s vintage-inspired glow.

Ideal for those who appreciate subtle drama and handcrafted detail, this ring suits daily wear and adapts well to resizing if needed. The semi-set format invites you to select a center diamond that resonates personally, making the design uniquely yours.
