Sell Ruby Jewelry · Nationwide, by Mail
Bizak & Co. buys ruby jewelry from sellers across the United States — mail it in on a free, fully insured label. Ruby is priced almost entirely on color: our trained gemologist reads saturation, hue and origin, and sends you the offer in writing — separate from whatever the metal is worth. An established Miami jewelry house since 1996.
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.
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."
No paperwork, moderately saturated red with visible heat treatment — appraised on color and clarity in person, offer made same day.
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.
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.

A gemologist reads color, clarity, origin and treatment, and emails a written offer.
Accept and you're paid the same day by bank transfer — or everything ships back free.
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.
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.
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.
