Our Philosophy

Where every diamond is celebrated

At Franklin & Co., we believe an exceptional diamond should never be concealed — it should be celebrated. Guided by this philosophy, we craft rings that elevate the stone above the band, allowing its brilliance to take centre stage.


Each piece is meticulously engineered to create the illusion of a floating diamond, held securely in a refined prong setting that maximises light and radiance. Every creation is not just jewelry — it is a legacy in the making.

Clarity of the Stone

Clarity refers to how free a diamond is from internal inclusions and surface blemishes. Fewer imperfections allow light to pass through more cleanly, enhancing brilliance and sparkle. Higher clarity grades are rarer, but slight inclusions often remain invisible to the naked eye.

FL / IF Flawless / Internally Flawless — Excellent
VVS1–2 Very Very Slightly Included — Very Good
VS1–2 Very Slightly Included — Good
SI1–2 Slightly Included — Fair
I1–3 Included — Poor
Color Scale

D to Z — The Spectrum of Purity

The diamond color scale ranges from D to Z, measuring tint from colorless to faint yellow. Less color enhances brilliance, rarity, and overall visual purity. At Franklin & Co. we source across the full spectrum to match every vision and budget.
