Le Vian produces a good line of jewelry (expensive) but remember that a chocolate diamond is a diamond that may have been enhanced by man. With extreme heat the diamond's brown color can be changed to a chocolate color, so this may effect the overall value of the diamond.
RESPONSE TO "Another Answer" To be clear, LeVian chocolate diamonds are not enhanced in any way. "Chocolate" is LeVian's protected trademark name for the brown diamonds they use in their jewelry pieces. The superior design of the piece, the stone's cut, clarity and consistently rich color are what sets these apart from other brown diamonds. If you want a third party opinion on the value of your gemstone jewelry or loose gemstones, you will need to contact an independant appraiser who is certified by GIA or similar organization to expertly appraise gemstones. Their written assessment will be based on replacement value for insurance purposes not resale value.
