It is graded \u003cb\u003eEye-Clean\u003c\/b\u003e on Stuller's quality scale — a calibrated stone cut to a standard millimetre size rather than a one-off crystal.\u003c\/p\u003e\u003cp\u003eBecause it is calibrated, we can usually replace or match it — useful for a pair, or if you want the same look in another size. Set it as the centre of your own ring in our ring builder, or buy it loose and keep it for a design of your own.
