{"product_id":"heart-faceted-lab-created-ruby-4x4-6x6mm","title":"Heart Faceted Lab-Created Ruby","description":"\u003cp\u003eCrafted from man-made corundum sharing the same chemical composition and durability as natural ruby, these heart-faceted lab-created rubies offer exceptional clarity with vivid, even coloration. Known as the \"King of Gems\" in Sanskrit, ruby has been among the most prized and sought-after gemstones since biblical times and remains the most valuable variety of corundum, commanding the highest per-carat price of any colored stone.\u003c\/p\u003e\u003cp\u003eThese lab-created stones display a vivid medium-to-dark purplish red hue that is eye-clean, making them an ideal choice for fine jewelry settings, metal clay work, and stone-in-place casting applications. Color ranges across the corundum family run from orangy red to purplish red, with pure vivid red to slightly purplish red representing the most highly valued tones. Because these are synthetic stones, they exhibit the consistency and clarity rarely achievable in natural rubies, where inclusions are common and heat treatment is nearly universal.\u003c\/p\u003e\u003cp\u003eClean with warm, soapy water.
