Myterra Gemstone Hardware

We are waiting for his next response

This order was for clearance amethyst spheres at $each on hardwareWe had only three, which we made into door knob pulls for himOur retail pricing on these are $each with quality stones. The two on black hardware are the same colorThe 3rd on satin is much lighter purpleHe
asked if they could be changed but the hardware is epoxied so the hardware does not come looseHe did not send us pictures and his last message was "Measured with a cloth tape, the difference in circumference is 3/of an inchThat’s significant considering differences in circumference are magnified more than differences in length."With calipers the difference is 2mm, about 1/thNext to each other the size is so minute that I was fine with them. We started on 5/with cabinet knobs sending pictures, then to door knobs sending pictures. Last response to him was: We had both amethyst spheres that matched in color on black hardware and their may be a difference very little between themThe color on the satin hardware amethyst does not match the others. Don't recall there being a difference that would frustrate you? Screw on the bottom of each of the pulls holds the sphere from rotating, but they are also glued not to move.and nothing from him after this............ We will credit the two for $if he returns them, and I will inform you that he did with the credit. ***

I am rejecting this response because: I have to wait until the installer comes on Wednesday.  If [redacted] is willing to wait, I would like to see how the two variations appear on the doors before deciding.  The installer can put the two different sizes together to see how noticeable it is.  He can also try the two smaller ones and I can determine if that appears better. If size appears OK I'll keep them.  If the two smaller ones are a better match because of size, I'll return the larger Black Matte and smaller Satin Steel for the switch.  If neither option appears OK, I'll take the option of returning the Black Matte for two different stones requiring additional cost.Thanks for the consideration.[redacted]
