Made to order — crafted for you in about three weeks.
A round lab-grown diamond of 0.75 carats — D color, VVS2 clarity, Excellent cut — carried by six platinum prongs on cathedral shoulders. This is the drawing we refine every year and change least: the proportions that flatter the most hands, in the metal that outlasts every trend.
The craftsmanship
Cathedral arches rise from the shank to meet the basket, transferring knocks away from the girdle — the reason this mounting has survived nine years of daily-wear resizings in our workshop ledger. The 950 platinum is work-hardened after casting so the six prongs keep their grip through decades of re-tipping cycles.
◆ Conflict-free sourcing, verified through our suppliers.
◆ Cast in recycled precious metal.
Cast in 950 platinum reclaimed from industry refining.

Care, warranty & services
Platinum care: Platinum develops a soft patina rather than wearing away. Restore the mirror finish any time with a professional polish — ours is complimentary — or embrace the patina; both protect the metal.
Diamond care: Diamonds attract skin oils, which dull their fire. Soak in warm soapy water weekly and brush behind the stone where residue collects; avoid touching the table facet.
Every Palencia Diamonds piece is inspected by a bench jeweler before it ships and is covered against manufacturing defects. Complimentary prong checks and professional cleaning are available on every piece we make — bring it in or send it to us any time.
One complimentary resizing where the design allows (full eternity bands and certain settings cannot be resized — the product page says so before you order).
Questions, answered
Is a lab-grown diamond a real diamond?
Chemically and optically, yes — the same carbon crystal, graded to the same 4C standards by the same laboratories. The report accompanying this piece states the origin plainly, as we do everywhere on this page.
Can this ring be resized?
Yes — one complimentary resizing within the first year. The workable range is listed in the specification grid; designs with stones set around the full band have narrower ranges.
Why six prongs instead of four?
Six prongs hold the stone if one fails and frame a round outline more evenly; four show more stone. For daily wear we recommend six.
