When you are shopping for loose gemstones and pearls, the decision often starts with form: do you want a polished, faceted stone that can go straight into a setting, or do you want an uncut stone you can keep as a specimen or have recut? In this head-to-head, the two natural, certified options are close on listed price, so the real separators are carat weight, cut, and color effect.
Quick Verdict
If your goal is a ready-to-set fancy cut with a color-change effect, the 10 Ct Natural AA+ CERTIFIED Alexandrite Color Change Fancy Cut Loose Gemstone at USD 22.49 is the one to choose. If you want an unusually large natural blue sapphire in rough form, the 1720 CT Natural Blue Sapphire Certified Rough Uncut Stone Huge Loose Gemstone at USD 24.99 gives you a dramatically bigger stone for about $2.50 more.

Where Each Product Wins
The Alexandrite wins when you want a polished, cut stone that is ready for the creative part of jewelry making. It is listed as eye clean, natural, and multicolor, and the color-change effect is a strong decorative asset. If you want to skip the early rough-cutting stage and work directly with a faceted stone, this is your pick.
The blue sapphire wins when you want maximum rough material in a single stone. It is listed as natural, eye clean, and blue, with an uncut form and a large carat weight compared to the Alexandrite. If you plan to have a stone custom-cut, or simply want a massive natural sapphire specimen, the size is the big advantage.
Product Notes
10 Ct Natural AA+ CERTIFIED Alexandrite Color Change Fancy Cut Loose Gemstone
The Alexandrite is listed with EGL certification and is described as natural, eye clean, and bi-color/multicolor with an asterism and color-change effect. The combination of a fancy cut and a color-change display makes it a strong candidate if you want a cut centerpiece that does not require pre-cutting. The limitation is that you are buying the stone in its finished cut form; there is no opportunity to reshape it as you could with a rough stone. If you need a large, polished loose gemstone that is ready to be designed into a jewelry piece, this one gives you that straight away.
1720 CT Natural Blue Sapphire Certified Rough Uncut Stone Huge Loose Gemstone
The blue sapphire is listed with GIR certification and is described as natural, eye clean, blue, and rough in form, with an asterism effect. The standout feature here is the enormous carat weight relative to the Alexandrite, and the uncut form means you can treat it as a specimen or send it to a cutter. The limitation is that it is not a faceted, ready-to-use stone; if you are looking for a polished blue sapphire you can set immediately, this rough stone will require additional work. For a collector or a custom cutting project, the size and listed price make it a compelling rough option.
Final Choice by Use Case
Choose the Alexandrite if you want a ready-to-set, color-change cut stone. Choose the blue sapphire if you want an unusually large rough stone. For a jewelry piece that needs a faceted center stone, go with the Alexandrite. For a project built around cutting rough material, or for a massive natural sapphire specimen, go with the blue sapphire.
