A marquise center stone flanked by two marquise side stones, set on an 18K rose gold band. Three stones represent past, present, future — the classic engagement symbolism. Specifications Center stone: Marquise lab-grown diamond center + two marquise side stones, IGI certified Color & clarity: D–F / VVS2 Cut grade: GIA Excellent equivalent Setting: Three-Stone Metal: 18K Rose Gold (also available in Yellow or White), hand-finished Band width: 1.8mm Inner diameter (US size 6.5): 16.9mm Certification: IGI Why this design Marquise is the longest cut profile — 100% length-to-width ratio extension over a round of the same carat. Originally cut for King Louis XV, it remains the strongest finger-elongating shape in bridal. In a three-stone arrangement, the side stones add lateral light return — the ring reads wider on the hand without enlarging the center carat. Made to order Each ring is hand-finished to order. Production takes 12–16 business days, plus 5–7 business days of insured DHL Express shipping. Each order includes the IGI certificate, one complimentary resize within the first year, and lifetime cleaning. Frequently asked How fragile are the points? The two points of a marquise are the most exposure-prone areas on any cut. We always set marquise rings with V-prongs at both tips for protection. Recommended setting check every 12 months. Is this a real diamond? Yes. Lab-grown diamonds are chemically and optically identical to mined diamonds — same carbon structure, same 10 Mohs hardness, same fire. The only difference is origin. Can I customize the metal or carat? Yes. Choose 14K or 18K white, yellow, or rose gold. Center stone ranges from 1ct to 5ct.

After the piece is received and passes inspection, we issue a full refund to the original payment method within 7 business days.

If an engraved or bespoke piece has different cancellation or return terms, we will disclose them in writing before payment. If no exception is disclosed, our standard 30-day return policy applies.
