The failure mode is choosing a diamond the week of the dinner.
Insured shipping plus the 3-day look at a returnable stone is the minimum once the diamond is confirmed. Your jeweler’s queue is extra.
A loose diamond can be the proposal object. A finished ring cannot be assumed if you have not booked the setting.
Request the diamond as soon as the USD budget and the shape are real. Carat Mate ships the certified loose diamond and its lab report to United States addresses. Prices on the site are in USD. Wrong-item returns may be considered within 3 days of delivery, subject to review.
