What Types of Lab Created Gemstones Does Gems N Gems Offer?
Gems N Gems lists lab created gemstones across five main families: diamond, ruby, sapphire, emerald, and moissanite, plus alexandrite and Paraiba. Each product page shows the growth method in the product name (CVD, Czochralski, hydrothermal), the shape (round, cushion, oval, octagon), and a price range that varies by size and quality. If you already know which gem family you want, the method name is the fastest way to narrow the catalog; if you are comparing options, the price ranges below give you a starting point.

What the growth method names tell you
The method is part of the product title, so you can filter by it directly:
- CVD (chemical vapor deposition) — used here for lab created diamond. The listing specifies DEF color and VVS quality.
- Pulled Czochralski — used for ruby, blue sapphire, and blue Paraiba. This is a melt-based pulling method, and the site applies it to corundum-family stones and Paraiba.
- Hydrothermal — used for Colombian emerald and oval emerald. This method mimics the solution-growth conditions of natural emerald.
Moissanite and the rough blue sapphire listing do not name a growth method in the featured block, so treat the method as unconfirmed for those two unless the individual product page states it.
Shapes, quality grades, and variants
- Shapes seen in the featured listings: round, cushion, oval, octagon, and rough (uncut).
- Quality grades: the moissanite listing carries an AAA grade and DEF color; the lab created diamond carries DEF color and VVS quality; the natural comparison stones are graded AAA.
- Variants: most listings show "Select options," meaning size and other variants are chosen on the product page. The price range reflects the cheapest to most expensive variant, not a single stone.
How price varies
Price tracks three things: gem family, size, and quality grade. The spread within one listing can be large — lab created diamond runs from $21.49 to $2,597.01, and pulled Czochralski ruby from $29.15 to $3,980.00. Emerald shows the opposite pattern: the octagon Colombian emerald reaches $1,199.00 while the oval emerald tops out at $245.00, so shape and source description matter as much as the gem name. The rough blue sapphire is listed at a single $90.00 price with no range.
Choosing between them
- Want maximum brilliance and a diamond alternative: compare CVD diamond against AAA moissanite. Diamond has the higher ceiling ($2,597.01) but also the lower entry point ($21.49); moissanite stays under $470.15.
- Want colored corundum: pulled Czochralski ruby and blue sapphire are the direct options, with Paraiba as the rarer blue-green variant.
- Want emerald: hydrothermal emerald comes in two shapes here — octagon (Colombian) and oval — at noticeably different price ceilings.
- Want a natural stone instead: tanzanite and aquamarine are the natural options shown alongside the lab created selection.
Before ordering, open the individual product page to confirm the exact size, grade, and variant price, since the featured block only shows the range.
