Product Description
Discover this pink ruby cushion cut gemstone and lab grown diamond split shank engagement ring, a statement piece that blends vintage inspired elegance with modern affordable luxury. The vivid 2.90 CT cushion cut pink ruby center stone is held in a secure four prong yellow gold setting, radiating rich color and antique inspired charm against the white metal band. The split shank band gracefully divides into two diamond encrusted strands, lined with 0.70 TCW round brilliant cut pave accent diamonds and crowned by two striking 0.20 TCW marquise cut lab created diamonds flanking the center gemstone. This art deco flair design in 925 sterling silver, with upgrade options in 10K, 14K, or 18K solid gold and 950 platinum across white, yellow, and rose tones, makes it one of the best affordable colored gemstone engagement rings under $400 for buyers asking, "What is the best ruby diamond ring for a romantic proposal?"
The two tone prong setting contrasts warm yellow gold prongs against a polished white band, creating an heirloom quality fine jewelry profile that draws the eye to the ruby's deep pink brilliance. The split shank band style, adorned with channel set round brilliant diamonds and elegant marquise side stones, offers a brilliant diamond border effect without the weight of a traditional halo cluster setting. With a 2.00 mm band width and comfort fit 1.70 mm depth, this ring sits beautifully for daily wear and pairs perfectly with a curved wedding band or minimalist stacking ring. Every lab grown diamond is EF-color, VS clarity, ethically sourced, conflict free, and certified with an Ouros authentic jewelry certificate.
Whether you are searching for a surprise commitment gift, a milestone anniversary present, a promise ring alternative, or the ultimate Valentine's Day proposal ring, this ruby cushion split shank design is ideal for anyone who loves bold colored gemstone jewelry with exceptional sparkle. The cushion cut ruby provides maximum light return and a flattering finger presence, while the marquise and round brilliant accents add over 0.90 TCW of sustainable lab diamond fire. It suits vintage jewelry lovers, colored stone enthusiasts, and modern buyers who want a head turning engagement ring that stands apart from the classic solitaire, a truly luxurious yet affordable celebration of love.
