Pink Diamonds, Alexandrite, Tourmaline: Which Loose Gemstone Should You Buy?

Four loose gemstones from $34.31 to $44.53: a 1.5 ct lab-grown pink diamond, a 2 ct lab-created pink stone, a 9.12 ct natural alexandrite, and an 8.90 ct tourmaline parcel.

Last updated Aug 17, 2026

When you're shopping for loose gemstones and pearls, the first fork in the road is the type of project you're planning. A one-stone ring asks for a single centerpiece with enough carat weight and clarity to stand alone; a multi-stone pendant or a jeweler's inventory benefits from a parcel of matched stones. The four listings here show both sides of that decision, with listed prices from $34.31 to $44.53 and very different personalities: a lab-grown pink diamond, a lab-created pink stone, a natural color-change alexandrite, and a faceted tourmaline parcel.

If you only remember one thing: read the stone count and creation method before you compare cut grades. All four list excellent cut, but '1.5 ct loose diamond' and '8.90 ct tourmaline parcel' are not interchangeable projects.

Quick take

  • For a single lab-grown pink stone with VVS1 clarity and an oval cut: the 1.5 CT Oval Cut Loose Lab Grown Diamond Fancy Pink Color VVS1 Clarity Loose Gems at $44.53.
  • For the lowest listed price in this group, with a 2 ct lab-created pink stone: the 2CT Cushion Cut Pink Color Loose VVS1 Diamond Premium Quality 7.50 MM Gemstone at $34.31.
  • For a natural color-change stone with certification: the Certified 9.12 Ct Natural AAA Alexandrite Color Change Round Cut Loose Gemstone at $38.99.
  • For a multi-stone parcel at $42.00: the Tourmaline Parcel 8.90 Ct Mixed Cut Loose Gemstone Lot Faceted.

Decision matrix

  • Choose the 1.5 ct oval lab-grown pink diamond if you want one polished single-stone centerpiece with VVS1 clarity and an oval silhouette.
  • Choose the 2 ct pink lab-created stone if you want a single 2 ct stone and are comfortable with a lab-created option.
  • Choose the alexandrite if color change and natural origin matter more than a traditional diamond look.
  • Choose the tourmaline parcel if you're setting multiple pieces and want a lot of faceted stones in one purchase.

1.5 CT Oval Cut Loose Lab Grown Diamond Fancy Pink Color VVS1 Clarity Loose Gems

1.5 CT Oval Cut Loose Lab Grown Diamond Fancy Pink Color VVS1 Clarity Loose Gems

This oval lab-grown diamond gives you a 1.5 ct single centerpiece in a fancy pink color, with VVS1 clarity and an excellent cut grade listed. The listing indicates IGI certification is available on request, which is useful if you need a stone that can be documented for a custom project. It is the highest listed price in this group, so it may not be the pick if you're assembling a low-cost parcel or experimenting with shape. It's also a lab-grown stone rather than a natural diamond, which matters if natural origin is a non-negotiable for your design.

2CT Cushion Cut Pink Color Loose VVS1 Diamond Premium Quality 7.50 MM Gemstone

2CT Cushion Cut Pink Color Loose VVS1 Diamond Premium Quality 7.50 MM Gemstone

This is the most direct way to get a 2 ct pink stone with VVS1 in the title and a 7.50 mm measurement, at the group's lowest listed price. Attributes describe it as lab-created with a loupe-clean clarity grade and an excellent cut. The listing uses lab-created as the creation method, so natural-diamond buyers should look elsewhere. If you want a pink stone with a smaller listed price and are open to a lab-created option, this one fits.

Certified 9.12 Ct Natural AAA Alexandrite Color Change Round Cut Loose Gemstone

Certified 9.12 Ct Natural AAA Alexandrite Color Change Round Cut Loose Gemstone

The headline feature is the color change: a natural 9.12 ct alexandrite that shifts under different lighting, with color change listed in both the title and attributes. Certification is listed, along with an eye-clean clarity grade and an excellent cut. It also comes from Brazil, which is noted in the attributes. The listed price sits between the two pink stones, so it's not the lowest-cost option, but you're paying for a single large natural stone with a color-change effect. If you're looking for a traditional clear diamond or a parcel of multiple stones, this doesn't match that brief.

Tourmaline Parcel 8.90 Ct Mixed Cut Loose Gemstone Lot Faceted

Tourmaline Parcel 8.90 Ct Mixed Cut Loose Gemstone Lot Faceted

This listing is for a lot, not a single stone: 8.90 carats total across mixed faceted tourmaline cuts. The attributes describe it as natural, eye clean, and not enhanced, and the listing notes that you'll receive the exact stones shown in the photos. If you're making a multi-stone bracelet, earrings, or a small custom cluster, this parcel gives you more than one piece to work with for a single listed price. The trade-off is that you don't get one large centerpiece; you get several smaller stones, so it's not the right choice for a solitaire-style design.

Final recommendation by use case

  • Custom ring with a single pink stone: 1.5 CT Oval Cut Loose Lab Grown Diamond Fancy Pink Color VVS1 Clarity Loose Gems.
  • Lower listed price option for a single pink stone: 2CT Cushion Cut Pink Color Loose VVS1 Diamond Premium Quality 7.50 MM Gemstone.
  • Natural color-change collector's piece: Certified 9.12 Ct Natural AAA Alexandrite Color Change Round Cut Loose Gemstone.
  • Multi-piece project: Tourmaline Parcel 8.90 Ct Mixed Cut Loose Gemstone Lot Faceted.
