History, Types, Cultural Significance Of Solitaire Setting Lab Diamond Engagement Ring
A solitaire engagement ring is the ultimate expression of love and elegance. It features a single, striking diamond as its centrepiece—no side stones, no distractions. The design speaks for itself: confident, classic, and enduring.
At The Karat Store, our solitaire setting lab diamond engagement ring combines tradition with modern ethics. Every ring is made using solid 14K & 18K gold in your choice of white, yellow, or rose gold. The diamonds are lab-grown using advanced technology, offering the same chemical, physical, and visual characteristics as mined diamonds—but with a lower environmental impact and zero conflict sourcing.
Choose from a variety of cuts, including round brilliant, oval, emerald, cushion, pear, and more. You can also choose your preferred setting style—four-prong, six-prong, bezel, or cathedral—to reflect your taste. Solitaire settings are extremely versatile and pair beautifully with almost any wedding band style.
