Rings can be manufactured to any desired size, as an approximate guide CRA has 6 sizes which are given as a top surface dimension:
X-SMALL (<10mmx10mm) SMALL (12mmx12mm) MEDIUM (15mmx15mm)
LARGE (20mmx20mm) X-LARGE (23x23mm) BIG BLING (>25mmx25mm)
When finalising your order form, please quote your individual bands in US Sizes. Quotations are provided for one mould size, which covers 4 ring sizes (Eg All ring bands are G,H,I & J in size). A wider range of band sizes (Eg Rings bands are between size G and T) will require additional moulds to be manufactured at the quoted rate. For orders in excess of 20 rings, CRA can provide a set of sizing rings free of charge, just ask us for more details.
