FROM ₹ 84,000Technical fine jewellery, engineered in Bengaluru. Every piece begins as a drawing; every drawing is dimensioned, toleranced and checked before a single gram of gold is melted.
Drawing MRU-2026-01, front elevation. Peel the build layer by layer, then sweep the section plane across the piece to read its cross-section like a machinist would.
Drag, or use arrow keys · everything left of plane A-A renders as cut section, hatched per IS 10714 convention.

Honest microns. These are the limits every MERU piece is measured against before it leaves the bench, and the instruments we measure them with.
Finger bore turned and gauged against a certified ring mandrel. Digital bore gauge, checked at three axes.
Drawn wire Ø 0.90 mm, micrometer-checked at each prong before setting. Tip pressure verified after stone seat.
Centre stone axis to shank axis, measured on a dial indicator jig. A crooked stone never ships.
Table heights across the 42-stone grid, sampled at 10 points under a calibrated depth microscope.
Every finished piece is inspected under 10x loupe, weighed to 1 mg, and sent for BIS hallmarking at a licensed assay centre (licence no. XXXXX). The stamped cartouche is shown on the drawing above. The inspection card ships with the ring.
Three more drawings currently in production. Each is engineered to the same tolerance sheet as MRU-2026-01.
Every commission starts the same way: a conversation, then a dimensioned drawing with your name in the title block. You approve the drawing before we approve the metal.
