Description

Composed of man-made corundum, this round faceted lab-created ruby shares the same chemical composition and durability as natural ruby. Known as the "King of Gems," ruby has been prized since antiquity for its vivid color and rarity. As the birthstone for July, it remains one of the most desirable gemstones in jewelry making. Available in a broad range of sizes from 1.00mm to 8.00mm, these stones offer consistent, predictable quality for professional jewelers and metalsmiths.

Features

  • Durability equal to natural ruby — corundum hardness
  • Vivid medium to dark purplish red color, consistent across the range
  • Eye-clean clarity with synthetic, standardized quality
  • Safe for firing in metal clay
  • Suitable for stone-in-place casting

Great value

Good red color. Not too pinky magenta like some lab grown rubies I've purchased. Excellent cut and true to size.

NOT calibrated

Given these are lab-created stones, I had a reasonable expectation they would be calibrated. They are not, and I ended up ruining an entire piece because (my fault) I didn't bother confirming the measurement before beginning the project. My stones were consistently sized, but a 4mm stone came in around 3.88mm, which, when burring a setting, makes a really big and disastrous difference. Lesson learned, but leaving the review so others don't suffer like I did.
