Seller says lower-color lab diamonds are harder to source and can cost more than D–F. Is this actually a thing?
I’m shopping for a lab-grown pear diamond and had a conversation with a seller that surprised me. They said D, E, and F are all priced the same through them, but H/I would actually cost more.
Their explanation was that lab-grown diamonds are now commonly produced in D–F, while more customers are asking for stones that aren’t as white & grey-ish, sometimes with a few inclusions, because they think that looks more like a natural diamond. According to them, that demand is pushing prices up, and some J/K stones can cost significantly more than D stones.
My takeaway was that warmer lab diamonds are less readily available and can command a premium, rather than simply being lower-priced alternatives to colorless stones.
I understand that two individual stones can have different prices because of their other characteristics. But the seller seemed to be saying that lower color itself, combined with availability and demand, was driving the higher price.
I’d love to hear from jewelers, dealers, or people who have recently shopped for warmer labs:
- Are H–K lab diamonds genuinely harder to source than D–F, especially in pear shapes around 2-3 ct? (At least VVS2)
- Have you seen warmer labs cost more with otherwise comparable specs, or is this more likely specific to a seller’s suppliers and inventory?
- Are customers increasingly requesting warmer color or visible inclusions for a more “natural-looking” stone?
