Semi- Mountings represent items that do not have a center stone set in them. If pictured with a center stone the center stone is not a genuine diamond and the price reflects such. All stones except the center are genuine and total weight represents the total weight excluding the center stone. Most semi mounts can handle a range of sizes of center stones, or Hoppe Jewelers can make a new piece to accommodate any size stone. For assistance or questions please call our sales staff.
