Notes: As gem and metal prices fluctuate regularly, prices received on the final quote may vary slightly from prices shown on our site. Most engagement ring listings, including solitaires and halos, do not include center stone pricing on the listing (pricing seen is for semi-mounts only and noted in the individual listing). Center stone pricing will be included on the final quote.
