Sapphires are treasured for their rich colors and timeless elegance, but it s important to understand how treatments affect their value. At Artisan LA, we carefully source our sapphires and work only with trusted vendors to ensure quality and authenticity.
Unheated Sapphires The rarest and most valuable. No laboratory can guarantee unheated, but reports can confirm when no evidence of heat is found.
Low Heat Treatment Subtle enhancements that are difficult to detect. This is a common and widely accepted practice that does not significantly reduce value.
Filling or Glass Injection A low-quality treatment that makes sapphires fragile. We avoid these stones, except in clearly disclosed, low-cost silver jewelry.
Beryllium or Diffused Treatment High-heat processes that alter color. These are easy to detect and considered lower in value.
High Heat Treatment Easily identified under magnification, leaving round inclusions and structural changes. These sapphires are more affordable but less rare.
For clients seeking the highest assurance, we recommend certification through GIA (Gemological Institute of America). Their reports take about 25 days and cost approximately $250.
Every sapphire we offer is vetted with care whether unheated or low-heat treated, your stone will be beautiful, durable, and honestly represented.
