Are raw and rough diamonds real diamonds?

Yes — they are 100% genuine, earth-mined natural diamonds. The only difference from a classic engagement-ring stone is that these are raw, rough or uncut rather than cut and polished into a colorless gem. That natural state is exactly what gives them their organic look and their much lower price.

What is a diamond slice, and what are polki slices?

A diamond slice is a thin, flat cross-section cut from a natural rough diamond, so it is broad and shallow with a rustic, often translucent look. Polki slices are flat, largely unfaceted natural diamond pieces long used in traditional handcrafted jewelry. Both are prized for an organic, one-of-a-kind character rather than bright sparkle.

What is the difference between a raw diamond, a slice, and a rose cut?

A raw diamond is an uncut natural crystal or rough stone; a slice is a flat piece cut from that rough; and a rose cut has a flat base with a faceted, domed top for a soft vintage glow. We carry all three so you can match the look to your design. See rose cut diamonds.

Why are raw diamonds and slices so much cheaper than a polished diamond?

Because they are natural-color, often opaque rough stones sold by the piece or by weight, not colorless faceted gems graded on the 4Cs. You get real diamonds — with all their hardness and character — at a fraction of the price, which is what makes them so popular for handmade and designer jewelry.

Do raw diamonds sparkle?

Not in the bright, fiery way a faceted brilliant does. Raw diamonds and slices have a softer, natural luster and a more translucent, earthy glow. If you want more sparkle, look for our laser-cut, faceted and rose-cut options, which add facets while keeping that natural-stone character.

How do you set a raw diamond or slice into jewelry?

It is easier than many people expect. A lot of our slices and rough stones are flat-backed and laser-cut specifically for easy setting, and a bezel setting is ideal for protecting the edges, while prong settings work well too. Slices are popular for rings, statement earrings and pendants

Are your raw diamonds conflict-free and natural?

Yes. Our raw diamonds and slices are natural, earth-mined and conflict-free. Each product page describes the stone honestly, and if you need specific sourcing details for a piece, just reach out.

Are the colors natural or treated?

Both, and we always disclose which. Many colors are completely natural — such as white, grey, black, yellow and cognac — while some are enhanced for a stronger hue, for example irradiated blues, heated blacks or color-enhanced pinks. The treatment is stated clearly on each product page.

How are raw diamonds and slices sold — by piece or by weight?

Both. Many stones are sold in sets of 1, 2, 5 or 10 pieces, and larger stones and slices are often priced by carat weight (CTW). Sizes range from tiny a few millimeters up to bold 20mm-plus statement stones, including one-of-a-kind pieces. Each listing states the exact size and quantity.

Can I get matched pairs, custom shapes, or wholesale quantities?

Yes. We offer matched pairs for earrings, laser-cut custom shapes and monogram initials, and wholesale parcels for jewelers and designers. Tell us the color, size or shape you need and our team will source it. Start a wholesale or custom enquiry.
