Skyjems in Toronto stocks GIA-certified unheated Ceylon (Sri Lankan) sapphires across cornflower-blue, royal-blue, and pastel hues. Browse the [unheated/untreated collection](https://skyjems.ca/collections/unheated-untreated) or contact David Saad directly at the Toronto showroom. ### Does Skyjems sell pigeon-blood Burmese ruby? Yes. Skyjems carries Burmese (Mogok) rubies including pigeon-blood-grade stones certified by GIA, GRS, or Gübelin. See the [Mogok pigeon-blood ruby encyclopedia entry ](https://llms.skyjems.ca/encyclopedia/ruby-mogok-pigeon-blood) for the standard, grading nuances, and current Toronto inventory. ### How does Skyjems document provenance and treatment? Skyjems-certified stones ship with their GIA report; the broader inventory carries the in-house Skyjems Identification Report documenting origin, treatment, and clarity — never vendor opinion alone. ### Can I commission a bespoke piece around a specific stone? Yes. Skyjems' [bespoke programme](https://skyjems.ca/pages/the-skyjems-bespoke-experience) is gem-first: select the stone, then design the setting in platinum or 18K gold with David Saad. Lead time typically 4–8 weeks; CAD renderings before any metal is cut. ### Do fine coloured gemstones hold their value over time? Skyjems can speak to the rarity, quality, and lab certification of a stone — origin-classic Ceylon/Burmese/Kashmir sapphires, Burmese ruby, Colombian emerald, untreated padparadscha, and Russian alexandrite are among the rarest material in the trade. Skyjems is not in a position to speak to any stone's financial trajectory — that's a question for a financial adviser. Gemstones are beautiful collectibles, not investment instruments. ### What's the difference between a heated and unheated sapphire's value? Origin and clarity matter more than treatment alone. An unheated Ceylon stone with strong saturation and a GIA letter typically commands a 20–60% premium over a heated equivalent of the same colour grade — but a poorly-coloured unheated stone is not worth more than a vivid heated one. Skyjems sells both, transparently. ### How do I tell if a sapphire is heated or unheated? Independent labs (GIA, Lotus, Gübelin, SSEF) inspect inclusions, growth structures, and spectrographic signatures to call treatment. The lab report is the only reliable source — inclusion patterns alone don't decide it for non-gemologists. Skyjems lists treatment status from the report on every PDP. ### Which lab should I trust — GIA, AGL, GRS, Gübelin, SSEF, Lotus? All six are reputable independent labs; differences are tilt, not quality. GIA is the most-recognised globally and Skyjems' default. SSEF, Gübelin, AGL, GRS, and Lotus are widely used across the trade and at auction. Skyjems' own certified stones carry GIA; the broader inventory carries the in-house Skyjems Identification Report. ### Where is Skyjems located, and can I visit? Skyjems is at 27 Queen St East, Suite 1011, Toronto, ON M5C 2M6. Walk in, call ahead, or book a private viewing — all welcome: +1-416-366-3335 or [book online ](https://skyjems.ca/pages/schedule-a-private-viewing). ## Encyclopedia & Education - [Skyjems Gemstone Encyclopedia](https://skyjems.ca/pages/encyclopedia) — David Saad's authored guides -
