How ruby is priced

Ruby is priced almost entirely on color. A true "pigeon's blood" red — pure red with a slight blue undertone, strongly saturated, evenly distributed — is the top grade in the trade and commands a significant premium over a stone that's brownish, purplish or washed out. Most rubies sold in everyday jewelry fall into a broad "commercial red" range below that standard; they still have real value, just not top-tier pricing.

Origin matters more for ruby than for almost any other gem. Fine rubies from Burma (Myanmar), particularly the Mogok region, have carried a reputation and price premium for centuries because of their color quality and rarity. Rubies from other sources — Thailand, Mozambique, Madagascar, Sri Lanka — can still be excellent stones, but generally sell for less than a comparable Burmese stone, especially once Mogok origin is documented on a lab report.

Heat treatment is the industry norm, not a warning sign. The large majority of rubies on the market have been heat-treated to improve color and clarity — this is standard, disclosed practice and doesn't disqualify a stone from a strong offer. What does move the number is treatment beyond simple heat: glass-filled or lead-glass-treated rubies (common in lower-cost jewelry) are worth substantially less than heat-only or untreated stones, because the filling is fragile and affects durability. A no-heat ruby with documentation is the exception that brings a real premium.

What people typically bring in

Engagement and cocktail rings, ruby-and-diamond tennis bracelets, estate pieces with a center ruby flanked by smaller diamonds, and vintage rings inherited from a parent or grandparent where the ruby was never appraised separately from "the ring."

1.5ct engagement ring

No paperwork, moderately saturated red with visible heat treatment — appraised on color and clarity in person, offer made same day.

Vintage tennis bracelet

Inherited from a relative, unworn in decades — evaluated stone by stone rather than priced as a single melt lot, since individual stone quality varies across a bracelet.

GIA-certified Burmese ruby

Old report showing Burmese origin and no heat treatment — this is the scenario where documentation adds the most to the offer, since origin and treatment are otherwise hard to verify quickly.

Frequently asked questions

Do you buy rubies without a certificate?

Yes. A lab report (GIA, AGL, HRD or similar) can speed up an appraisal and support a higher offer when it documents origin or confirms no heat treatment, but it isn't required to get an offer. Our gemologist grades color, clarity and treatment in person either way.

Is heat-treated ruby worth less?

Not meaningfully — heat treatment is the industry norm and doesn't disqualify a stone from a strong offer. What moves the number down is treatment beyond simple heat, such as glass-filled or lead-glass-treated rubies, which are worth substantially less because the filling is fragile.

Is it safe to mail an expensive ruby?

Yes — Bizak & Co. emails a prepaid, fully insured FedEx label (through IFS/In4Sure) covering the full value of your piece, tracked door to door with signature required at every handoff, both ways. You never arrange or insure your own shipment.
