About Private Fine Jewelry
The Private Fine Jewelry Collection is TimeMachinePlus's own house line — a small-batch selection of lab-grown diamond jewelry we source, inspect, and stand behind ourselves. Each piece is crafted in solid gold and set with independently graded lab-grown diamonds — real diamonds, identical in look, chemistry, and brilliance to mined stones, at a smarter value — backed by our 2-Year TimeMachinePlus Warranty, free insured U.S. shipping, and easy 30-day returns.
