About This Piece
This half-eternity wedding band sets an elegant pattern of alternating marquise and round brilliant lab grown diamonds across the front of the band, totaling 3/8 carats. The pointed marquise stones and soft round brilliants trade off down the row, creating a rhythmic, slightly vintage line that reads as more intricate than a standard pavé band. It layers easily with a solitaire or halo engagement ring and works just as well worn alone.
Each band is made to order in solid gold, available in 14K and 18K white, yellow, and rose gold, with platinum offered as well. The half-eternity layout keeps the diamonds across the top of the finger, which makes the band comfortable for daily wear and simple to size.

Frequently Asked Questions
Lab-grown diamonds are physically, chemically, and optically identical to mined diamonds. The only difference is their origin — they are created in controlled laboratory conditions rather than extracted from the earth, resulting in a significantly lower environmental impact and more accessible pricing.
Bands range from delicate (0.10–0.50 ctw) for understated daily wear up to statement pieces (1.50 ctw and above). The total carat weight listed is the combined weight of every accent stone set on the band.
This band is designed to stack beautifully with engagement rings and other bands of similar profile. Its low-profile setting sits flush enough to avoid catching on adjacent rings, and the prong stones won't snag on a paired solitaire.
Yes. Diamonds are the hardest material (10 on the Mohs scale), making them exceptionally durable for daily wear, and the band itself is solid 14K or 18K gold (or platinum) for long-term durability. We do recommend taking it off during heavy activity — gym, lifting, or anything abrasive — to keep the prongs and finish in their best condition.
Clean your band regularly with warm water, mild dish soap, and a soft brush. Soak for 20–30 minutes, gently brush around the stones and band, then rinse and pat dry. Professional cleaning is recommended once a year. White-gold bands benefit from occasional rhodium re-plating to maintain their bright finish.
