The house
We buy where the jewelers buy.
DiaGems Manila — DG-MCM — deals in natural diamonds, colored gemstones and pearls from Quezon City, Metro Manila.
How we buy
We buy on the floor, not from a catalog.
We buy in person at the international jewelry shows — the Jewelry & Gem ASEAN fair in Bangkok, and the Hong Kong International Jewelry Show. Buying on the floor means we choose each stone ourselves and deal with the supplier directly, rather than taking whatever a local wholesaler has left.
Authenticity
Every stone comes with its certificate.
Each piece we sell is supplied with its certificate. Before you pay, you see the piece and the paperwork — on a video call, or in person at a viewing in Quezon City. If something doesn't match what we told you, it doesn't leave our hands.
Seeing beats trusting.
Buying fine jewelry online asks a lot of a stranger. So we don't ask. We put the piece in front of a camera, or on a table, and let you look at it — the stone, the setting, the certificate — before any money moves. Cash on delivery, nationwide, for the same reason.
