Precious Gemstone Buyer Toronto

GoldAgo purchases all types of precious and semi-precious colored gemstones including rubies, sapphires (all colors), emeralds, tanzanite, alexandrite, spinels, garnets, tourmalines, aquamarines, topazes, and many others. We buy both loose gemstones and jewelry set with colored stones. Fancy colored diamonds including yellow, pink, blue, and other colors are also purchased. Treated and untreated stones are both accepted with appropriate valuation. Single stones and collections are welcome.

We evaluate colored gemstones primarily on color quality—hue, tone, and saturation. Different gemstone varieties have different color preferences. Clarity standards vary by stone type—emeralds are expected to have inclusions while other stones should be cleaner. Cut quality affects brilliance and color presentation. Carat weight affects total value with larger stones having higher per-carat rates. We also identify treatments which affect valuation. Professional assessment ensures accurate pricing based on current market standards.

Yes, treatments significantly affect colored gemstone value. Most rubies, sapphires, and tanzanite are heat-treated, which is standard and accepted. Emeralds are typically oiled to improve clarity. Treated stones are valued lower than untreated equivalents of similar appearance. We identify treatments during examination and value accordingly. Untreated stones with laboratory certification command significant premiums. Both treated and untreated stones are purchased with fair market valuation reflecting treatment status.

We purchase both loose gemstones and gemstones mounted in jewelry. Loose stones receive straightforward valuation based on stone quality. Mounted stones are evaluated in the setting and can be removed for precise assessment if necessary. Some jewelry may be worth more complete than the sum of parts—we assess both approaches and offer the higher value. The precious metal in mountings is also valued when stones are removed. Bring gemstones in any form for professional evaluation.

Traditionally, precious gemstones include ruby, sapphire, emerald, and diamond. Semi-precious includes all other colored stones. However, this distinction is outdated in the modern market. Fine quality spinel, alexandrite, padparadscha sapphire, and other "semi-precious" stones can exceed the value of "precious" stones in lower qualities. We evaluate each stone based on its individual quality and current market demand regardless of traditional categories. Exceptional stones in any variety receive appropriate valuation.

Yes, we purchase fancy colored diamonds including yellow (canary), pink, blue, green, champagne, cognac, and other natural colors. Yellow diamonds are most common in values from faint to fancy vivid. Pink and blue diamonds are exceptionally rare and valuable. Natural colored diamonds are distinguished from treated colored diamonds. Color origin certificates from GIA or other laboratories enhance value for significant stones. Both natural and treated colored diamonds are purchased with appropriate market valuation.

Tanzanite is valued based primarily on color quality—deep blue-violet colors command highest prices. The strength of the blue versus violet pleochroism affects value. Larger stones have higher per-carat values. Most tanzanite is heat-treated to develop the blue color, which is standard and expected. Unheated tanzanite is rare and commands premiums. Clarity standards are relatively high compared to other colored stones. We assess all quality factors and current market demand when valuing tanzanite.

Certification from reputable laboratories like GIA, Gubelin, SSEF, or AGL can enhance value for significant stones, especially those claiming untreated status or prestigious origin. However, certification costs may not be recovered in the selling price for moderately valuable stones. We evaluate uncertified stones using professional gemological standards and provide fair market value. If you have certificates for your gemstones, bring them—we verify certificates and factor them into pricing when they add value.

We purchase damaged gemstones based on remaining value. Chips, scratches, and cracks affect value but don't eliminate it. Some damaged stones can be recut to smaller sizes, while others may only be suitable for commercial uses. We assess damage and value accordingly based on remaining potential. The precious metal in damaged jewelry also has value. Even heavily damaged stones often have some recoverable value. Bring damaged gemstones for professional assessment of remaining worth.

Certified cheques offer guaranteed funds. Cash available for transactions under regulatory limits. No payment method fees—choose what's most convenient.
