Your Fine Gemstone Experts: Nicholas Estate Buyers

Work Directly With a GIA Graduate Gemologist | Nicholas Estate Buyers

Colored gemstone value can be influenced by color, tone, saturation, transparency, clarity, cut, carat weight, geographic origin, treatment, laboratory documentation, rarity and current market demand.

At Nicholas Estate Buyers, your gemstone or jewelry is evaluated by professionals experienced with fine jewelry and important colored stones.

Expert Gemological Evaluation

We evaluate the characteristics that distinguish an exceptional natural gemstone from ordinary commercial material.

Complete Jewelry Evaluation

For mounted gemstones, we evaluate the entire piece rather than viewing the stones merely as material to be removed. Fine diamonds, precious metal, craftsmanship, age, maker and design can all contribute to value.

Strong Market Knowledge

Our experience buying and selling fine estate jewelry allows us to evaluate pieces based on their desirability within the actual secondary market—not simply their metal weight.

Private & Professional

Evaluations are handled discreetly at our Fort Lauderdale location, with no obligation to sell.

What Makes a Colored Gemstone Valuable?

Two stones of the same variety and carat weight can differ dramatically in value.

When evaluating an emerald, ruby, sapphire, alexandrite or other important colored gemstone, we may consider:

Color
Fine color is one of the most important factors affecting the desirability of a colored gemstone.

Origin
For certain gemstones, geographic origin can materially influence market desirability when supported by appropriate laboratory testing.

Treatment
Heat treatment, fracture filling, diffusion, oiling and other treatments can affect value. Untreated examples of certain gemstones can command substantial premiums.

Size
Large fine-quality natural gemstones can become increasingly rare as carat weight increases.

Clarity & Transparency
Clarity is evaluated differently for each gemstone species, but transparency and the nature of inclusions can have a significant effect on value.

Laboratory Reports
Reports from respected gemological laboratories can provide important information regarding identity, treatment and, in certain cases, origin.

The Jewelry Itself
A valuable gemstone mounted in an antique, signed, designer or exceptionally well-made piece should be evaluated as part of the complete jewel.

Before Selling Your Emerald, Ruby, Sapphire or Alexandrite

Do not have a jeweler remove an important gemstone simply because you are considering selling it. We can evaluate gemstones while mounted, and the original jewelry may contribute additional value.

Keep Any Laboratory Reports

GIA, AGL, Gübelin, SSEF and other laboratory documentation can be useful when evaluating significant colored gemstones.

Bring the Entire Piece

If you have a gemstone ring, necklace, bracelet, earrings or brooch, bring the complete item rather than separating the stone from the gold or platinum.

Bring Original Documentation When Available

Old appraisals, receipts, designer boxes, certificates and provenance can sometimes provide useful information.

Avoid Assuming an Old Appraisal Equals Current Market Value

Insurance replacement appraisals and secondary-market purchase values serve different purposes. We evaluate the item based on its characteristics and current resale market.

Selling a Fine Gemstone Should Begin With a Proper Evaluation

Whether you are selling a single important colored gemstone or an entire collection of estate jewelry, Nicholas Estate Buyers offers a straightforward and confidential process.

Our specialty is identifying value that can be overlooked when a gemstone is treated simply as another loose stone or when an entire jewel is valued only for its gold content.

Have You Been Told to Remove the Stones Before Selling Your Jewelry?

If you have emeralds, rubies, sapphires or other fine gemstones mounted in gold or platinum jewelry, we recommend allowing us to examine the piece in its original form first.

A gemstone ring, bracelet, necklace, brooch or pair of earrings may have value because of its:

  • Gemstones
  • Diamonds
  • Precious metal
  • Designer or maker
  • Age and period
  • Construction
  • Rarity
  • Provenance
  • Value as a complete piece of jewelry

Once stones have been removed and the mounting has been melted, that additional value may be permanently lost.

We purchase complete fine gemstone jewelry—not simply loose stones left after the precious metal has already been sold.
