Q. What is “sizing”?
A. Like all jewelry, rings are cast and manufactured to a certain industry standard. To change the diameter or size of a ring, a qualified jeweler must modify the shank. Ring sizes are unisex and are number based, running in ½ sizes.

Available Ring Sizes from Kohinoor Diamonds
Q. What are the standard ring sizes from Kohinoor Diamonds?
A. For Women: Standard in-stock size (depending on manufacturer) is 7; check the product page to confirm the size and its availability. Typical ring sizes available: 5 to 9 for women, including ½ sizes (5, 5 ½, 6, 6 ½, etc.).
A. For Men: Standard in-stock size (depending on manufacturer) is 10; men’s sizes range from 8-12, including half sizes (8, 8 ½, 9, 9 ½, etc.); check the product page to confirm the size and its availability. Wider bands and rings tend to run smaller. You may want to consider ordering half a size larger than your normal ring size for proper fit.
Q: Can all rings be resized if purchased originally in another size?
A. No. Some rings and bands cannot be resized due to their unique metal alloy* or design. Bands in very hard metals like titanium must be cast to the desired size by the manufacturer, while platinum bands are only sizeable to a few sizes above or below the original casting size. Unique ring designs such as eternity bands or channel-set diamond bands are usually manufactured only in the standard sizes; to maintain the strength and design integrity of the ring, the construction should not be altered. And rings with gemstones along the shank or intricate carving and engraving may not be able to be sized down more than one half or full size, if at all. If you need a designer’s ring of this type, you should order one to be cast in the size desired.
Q: Can special size rings be ordered?
A. Yes, in many cases, different sizes are available on many ring styles. However, this depends upon the physical design and the manufacturer. If you know your ring size (or that of the recipient) is much larger or much smaller than the standard ring size, you may consult specialists via phone or e-mail or visit Kohinoor Diamonds store to talk with our in-store specialists to find a suitable style of ring to fit your needs. However, if you have a specific ring style in mind that you need in a different size than is offered on the site, you will need to determine if a larger or smaller custom size of that specific desired ring style is available from the manufacturer.
For a special size, please send us an e-mail at email@example.com and specify the custom size and style you were looking for and we will do our best to accommodate your request by checking the availability and feasibility of rendering this ring in the desired size with the manufacturer and/or expert jewelers, and then returning with a quote and timeframe.
Note that most custom orders will incur additional time both for getting quotes and the actual manufacturing as well as additional cost for custom construction. For example, adding more metal such as gold, silver or platinum or additional gemstones to make a larger size, or reconfiguring the structural design of a piece to make it much smaller takes additional effort and cost for both materials and expert labor on the part of the manufacturer or expert jeweler.
Q. How much additional time should I allow for sizing and special orders?
A. In general, ring sizing to a standard ring can add up to five (5) days to delivery time on most rings. Please check for availability of each product before purchasing. For special size orders, please allow additional time. Custom casting of special size titanium bands, for example, can run up to 10-12 weeks, while other special orders can be ready in a few days, so please contact us for availability with our manufacturer before ordering if time is of the essence.

- Make sure the INSIDE diameter of the ring lines up with the OUTSIDE of the circle closest in size. If the ring is between circle sizes, go up to the next ½ size. This is the approximate ring size.
