Gem Quality

Chatham-Created Gems gemstones are gem quality, which means there are inclusions visible to the naked eye。

Weight Ranges

Unlike diamonds, colored stones are cut to maximize color。 The beautiful color of Chatham-created gems is achieved by hand-cutting each individual stone to best maximize color, therefore there is some variance in the cutting depth, pavilion bulge etc。, which translates to a weight range。 Keep in mind, a heavier stone does mean the most beautiful stone。 Let us pick the most beautiful stone we have available for you。

Carat Weight

Carat is a measurement of weight, not size。 All of the Chatham gemstones within a particular size and shape will have the physical measurements specified, ie。 7x5mm or 6x6mm。 Due to different densities among gemstones, it's best to order a colored stone based on the physical mm size you need, not the carat weight。 Ordering by carat weight creates confusion。 For example, a 6。5mm round diamond is approximately 1 carat, but a 6。5mm round sapphire is approximately 1。45 carats。 This carat weight difference is due to the different densities between sapphire and diamond。 It's like comparing a 3-inch ball of lead to a 3-inch ball of Styrofoam。 They are both the same size, but the lead is denser and therefore, heavier。 Again, getting a heavier gem doesn't mean the most beautiful。 Let us pick the most beautiful for you。


To offer you more selection, our orders ship directly from Chatham. Chatham simply does not photograph each individual stone. It takes sophisticated camera equipment and editing time to take photos that accurately capture the beauty and color of a gemstone. Cell phone cameras do not accomplish this. Likewise, monitor settings can affect how a stone looks from one computer to another. The best way to judge the true beauty of a stone is to see it in person. We promise to pick the prettiest stone available when you order. If you need assistance, please call 970-535-4139 to speak to our gemologist.
