6 Carat Marquise-Cut Lab Diamond Three-Piece Bridal Set
This three-ring bridal set features a 6.00 carat marquise-cut lab-grown diamond as the centerpiece. The engagement ring showcases an F color, VVS2 clarity diamond—virtually flawless with exceptional brilliance. The marquise cut's elongated, pointed shape maximizes visual size and creates a dramatic silhouette that enhances finger coverage.
Two matching wedding bands complete the set, each adorned with oval-cut lab-grown diamonds. The bands nestle flush against the engagement ring, creating a unified trio. All three pieces are crafted in 18K white gold with a seamless fit design. The engagement ring features a six-prong setting that secures the marquise diamond while maximizing light performance. The wedding bands feature half-eternity styling with oval diamond accents that complement the center stone's elongated profile.
Center Diamond Specifications
The 6.00 carat marquise-cut lab-grown diamond delivers exceptional quality with F color grade (colorless range) and VVS2 clarity (virtually no inclusions visible under 10x magnification). The brilliant-cut facets of the marquise shape create intense sparkle while the elongated form provides maximum visual impact for the carat weight.
Three-Piece Set Design
The engagement ring pairs with two coordinating wedding bands, designed to sit flush on either side. The oval diamonds on the bands echo the marquise's lengthened shape, creating visual harmony across all three pieces. Each ring can be worn individually or as a complete set. The 18K white gold construction ensures durability and a lustrous finish that complements the colorless diamonds.

Care Instructions:
-
Cleaning: Clean all pieces of the set regularly with mild soap and warm water. Use a soft brush to gently scrub around the prongs of the marquise diamond and along the channels of the oval diamonds. Rinse and dry thoroughly to ensure each diamond in the set sparkles.
-
Routine Maintenance: Due to the multiple components, have a jeweler inspect how the rings fit together during your annual check-up. They will ensure the marquise's prongs remain tight and the oval diamonds on the bands are secure. Professional cleanings for all three rings will keep the set shining uniformly.
-
Safe Handling: When wearing the full set, be mindful that it's a substantial trio of rings. Remove the set (or at least the engagement ring) during activities where it might be subjected to hard knocks or caught on materials (the pointed tips of the marquise deserve extra care). Avoid exposing the rings to chemicals like chlorine or bleach by taking them off before swimming or cleaning.
-
Storage: Store the engagement ring and bands together in a way that prevents them from rubbing against other jewelry. Ideally, keep them in the same bridal set box or a fabric-lined compartment that holds them snugly side by side. This preserves their matched shape and prevents any scratching from other items. Keep the storage area dry and moderate in temperature to protect the metal and diamonds over time.
Certification & Made-to-Order
Handcrafted to order. The carat weight of your center stone is shown in the title and details above. A center or solitaire diamond over 0.50 ct includes its own IGI certificate (natural over 0.30 ct, GIA); colored gemstone centers and the smaller hand-matched accent diamonds (pavé, halo, eternity, and tennis) are not individually certified, as is standard in fine jewelry — what is listed is their carat or total carat weight. Every Irdoja diamond is graded to our D–E color, VS–VVS clarity, Excellent-cut standard, and any certificates accompany your finished piece.
Every Irdoja piece is handcrafted to order — please allow 3–4 weeks for production (up to 4–6 weeks for custom designs).
Shipping is complimentary and fully insured on every order, with no minimum. Your piece ships via insured carrier with signature required for security, and most U.S. deliveries arrive within 2–5 business days once it leaves us — with a tracking number emailed the moment it ships.
