Blacknest Select — Lab-Grown Diamonds Ready to Order
Blacknest Select is our curated lab-grown diamond buying path for shoppers who want a luxury shortlist instead of scrolling through thousands of loose stones.
The full Nivoda loose-stone search stays available for clients who want to browse deeper. The public finder supports lab-grown and natural diamonds up to 5.00ct, with public checkout intentionally capped under $9,999.
Any diamond, gemstone, precious metal build, or custom request above the public cap is handled privately through consultation, availability review, and approved payment arrangements before any order is accepted.
