Frequently asked questions
-
Is your sapphire real, or is it diffused / glass-filled?
Sapphire is corundum, the same mineral as ruby, with non-red colors classified as sapphire. The disclosure trap to know about in the broader bead trade is beryllium diffusion — lattice diffusion of an external element to alter color, common in cheap yellow, padparadscha, orange, and some blue. Lead-glass-filled, fracture-filled, and synthetic / lab-created sapphire are also separate commercial categories. Treatment status (Heated, Natural / Unheated, Diffused, Filled, Synthetic) should be disclosed — ask before buying if a strand doesn't specify. -
Is the sapphire heated?
Almost all bead-grade sapphire is heat-treated. Heat treatment is permanent, stable, and the industry-standard treatment for sapphire — it's not a quality knock, but it is information you should have. Treatment status should be disclosed; strands marked "Natural" or "Unheated" are the smaller untreated tier and are priced accordingly. Ask before buying if the page doesn't specify treatment. -
What is multi sapphire?
Multi sapphire is a faceted rondelle strand — typically 2mm–3mm microfaceted — with a mix of natural sapphire colors across the strand: green, yellow, blue, pink, plum, orange, and sometimes peach or violet. The colors are not dyed; they are the natural fancy-sapphire range mixed within one strand. Multi sapphire is one of the workhorse formats in contemporary fine-jewelry stacking-bracelet design. -
Are pink, yellow, green, and white sapphire real sapphire?
Yes — all are corundum, the same mineral as blue sapphire and ruby. The trade calls everything other than red corundum "sapphire," with color names attached (pink sapphire, yellow sapphire, green sapphire, white sapphire, padparadscha sapphire). Color comes from trace-element chemistry: chromium for pink, iron-and-titanium for blue, iron alone for yellow and green, and so on. Padparadscha — orangish-pink — is the rarest natural color. -
What's the difference between Ceylon, Madagascar, and Montana sapphire?
Ceylon (Sri Lankan) sapphire is the historical benchmark for blue: cornflower-to-cobalt blue with high transparency. Madagascar has been the dominant fine-sapphire volume source since the 1990s and is the bead-trade's primary source for multi-color and fancy sapphire — it produces the full color spectrum. Montana sapphire is American-origin, celebrated for teal, green, and pale-blue registers, often unheated; Montana production is faceting-rough rather than bead-rough, so Montana bead strands are rare. "Montana-style" marketing without explicit Montana provenance is a common mislabel to watch for — origin should be disclosed.
