The Marquise solitaire. Its shape is stated consistently as a marquise, while the OM-RE listing names round, princess and pear in different fields.
Is the OM-RE ring worth the savings?
If the stone is truly a 2ct IGI-certified VS lab diamond in 14k gold, $749.00 at Walmart as of November 5, 2026 is about $1,000 less than the Marquise. Ask for the IGI report number and confirm the shape before buying.
Which has better diamond color?
The Marquise solitaire, graded EF. The OM-RE ring is graded Near Colorless, a wider range that can include stones closer to J.
Which offers more ring sizes?
The OM-RE ring, listed in sizes 3 to 11.5. The Marquise solitaire is listed only in stock size 7.
Does either ring come with a certificate?
The OM-RE ring is IGI certified. The Marquise listing does not state a lab certificate, so ask the seller for one.
