US guides
There is no rule that a ring must cost a fixed number of months of salary. That line is a slogan, not a budget.
Decide the diamond number in USD first, using live listings. Then the setting with a US jeweler. Then the wedding. Mixing them into one “ring budget” hides a weak cut.
Lab-grown centers are how many US budgets keep a size they like without taking the natural-diamond premium.
Shop the diamond as its own line item. 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.
