What this is

BlueLagoon is our internal buy-price cheat sheet for Ceylon sapphires. It turns the Gemports Q2 2026 ceiling bands into quick USD, LKR, and CZK numbers so everyone on the team negotiates from the same baseline — on the bench, over WhatsApp, or before a wire.

How to use it

• Colour family — pick Blue, Pink, Yellow, Lilac, Parti, or Padparadscha.
• Colour grade — face-up colour tier (vivid down to pale). This sets the Gemports ceiling band.
• Heat / Natural — heated vs unheated. Natural ceilings are higher.
• Carat (CT) — weight band drives $/ct; sub-1 ct stones use reduced reference rates.
• Cut & optics — adjust for window, clarity, saturation, cut, and other real-world deductions.

Reading the price tiles

All four tiles are percentages of the adjusted Gemports ceiling for that stone:

• Max buy (45%) — walk-away ceiling for a normal street negotiation.
• Good deal (30%) — strong buy; use when optics and colour are clean.
• Colombo (90%) — local direct / retail reference band.
• Prague (165%) — EU retail / online reference band.

Padparadscha note

Commercial pad tiers (medium, light, pale) use dedicated pad FOB marks — not blue-sapphire row percentages. Even pale padparadscha should price above yellow and lilac light. Fine vivid/deep pads still use the premium Gemports model.

Team workflow

Use the app to sanity-check a quote before you commit. Agree on family, grade, treatment, and carat first, then layer quality adjustments for the actual stone in hand. Numbers are negotiation anchors — not a substitute for inspecting the stone or your export paperwork.
