What the Appraiser Is Actually Checking — and Why It Matters
When you bring diamond jewelry to King Cash, the appraisal isn’t a black-box estimate handed to you on a slip of paper. You’ll see the process unfold in real time. The appraiser works through each of the six factors below, explains what they’re observing, and ties each observation back to resale demand before arriving at a number. Knowing what each factor means lets you follow along, ask the right questions, and understand exactly where your offer comes from.
The Six Diamond Grading Factors, Explained
Size
Size describes the physical dimensions of the stone. A larger diamond is generally rarer, which tends to push resale demand — and your offer — upward. That said, size never tells the whole story on its own. You’ll often see an appraiser set two stones of different sizes side by side and explain why the smaller one may carry a stronger offer once cut, clarity, and color are factored in.
Cut
Cut is the most misunderstood of the six factors, so it helps to draw the distinction clearly: shape describes the outline of the stone — round, oval, princess, cushion — while cut describes how well the stone’s facets, proportions, and symmetry work together to reflect light. A diamond cut to strong proportions returns light upward through the crown, producing the brightness and sparkle that resale buyers respond to. An off-proportion cut traps or leaks light, making an otherwise good stone look flat and dull.
During your in-store evaluation, you’ll watch the appraiser examine how the stone performs visually — whether it brightens under direct light and how cleanly the facets align. Both observations feed directly into the resale demand assessment.
Clarity
Clarity measures the presence of internal characteristics called inclusions and surface features called blemishes. In practice, inclusions can look very different from one another: a crystal inclusion might appear as a tiny dark or whitish pinpoint; a feather looks like a small crack or fracture; a cloud is a hazy grouping of microscopic crystals; a needle appears as a thin, elongated sliver. A blemish on the surface might show up as a faint scratch or small chip on the facet edge.
During your evaluation, the appraiser inspects the stone directly to locate and assess any inclusions or blemishes present. Fewer and smaller inclusions generally mean a stronger offer, because the stone is more appealing to the resale buyer standing on the other side of the transaction.
Color
In white diamonds, color refers to the degree of colorlessness. A faint yellow tint, even one that’s hard to spot face-up, becomes much more visible when you tilt the stone face-down against a white background — you’ll see the appraiser do exactly that during your in-store evaluation. Face-up, the brilliance of a well-cut diamond can mask slight color; face-down, there’s nowhere for tint to hide.
Checking color at home under warm-toned or variable lighting produces unreliable results, which is one reason an in-store appraisal gives you a far more accurate picture than a self-assessment. Less visible tint generally means stronger resale demand.
Setting
The setting — the metal framework and design holding the stone — contributes to the total value of the piece beyond the diamond alone. The appraiser reviews the metal type, the craftsmanship of the setting, and any wear, damage, or repairs visible in the metalwork. A well-made setting in good condition adds to the overall offer; significant wear or damage works in the other direction.
Overall Condition
Overall condition covers the physical state of both the stone and the setting together. Chips on the diamond’s surface, scratches across the table, or damage to the prongs all factor into the final evaluation. Bring your piece in as-is — broken, inherited, or simply unworn jewelry is evaluated the same way, with the offer based on what the stone and metal are actually worth at current market value.
| Factor | What You’ll Watch the Appraiser Check | Why It Affects Your Offer |
|---|---|---|
| Size | Physical dimensions of the diamond | Larger stones are rarer and tend to increase resale demand |
| Cut | Proportions, symmetry, and light performance | Drives how appealing the stone looks to a resale buyer |
| Clarity | Inclusions (crystals, feathers, clouds, needles) and surface blemishes | Fewer inclusions increase resale appeal |
| Color | Stone placed face-down against white to spot faint tint | Less visible tint increases resale demand |
| Setting | Metal type, craftsmanship, and condition of the mount | Adds to total piece value beyond the diamond alone |
| Overall Condition | Chips, scratches, or damage to stone and setting | Damage or wear reduces resale value |
How King Cash Calculates Your Offer
Offers are based on item condition, authenticity, current market value, and resale demand — all assessed in-store before you’re asked to decide anything. The appraisal is always free, and loans range from $1 to $50,000 with cash provided on the spot. No credit check is required.
If you’d rather get a sense of what your piece might be worth before making the trip, phone-based appraisals are available at no charge. Call the Lindenhurst location at (631) 991-8866 or the Huntington location at (631) 223-2173.
Pawn or Sell: Your Call After the Appraisal
Once you’ve watched the evaluation and heard your offer, you choose: pawn or sell.
Pawning lets you retain ownership while King Cash securely holds the piece as collateral. Pawn loans are available as short-term 30-day or long-term up to 4-month options. When you meet the loan terms, your diamond jewelry comes back to you. Low interest rates and an easy repayment policy apply, and written transaction details are provided for every pawn loan.
Selling outright converts the piece to immediate cash with no repayment terms — straightforward if you have diamond jewelry you no longer wear, inherited pieces, or broken items sitting unused.
Both options start with the same free appraisal, and walk-in evaluations are welcome at both locations during regular business hours — no appointment needed.
